Trans-Canadian Customized: Michael Ritzker’s 1976 BMW R90S…
In 2015, a minimum of Peter Egan of Cycle World declared that the BMW R90S, launched in 1974, was “the BMW that invented sport-touring.” The bike was meant to compete in opposition to the likes of the Honda CB750, Kawasaki Z1, Norton Commando, and different such machines.
Nevertheless, in true BMW style, this 900cc Hans Muth-designed flagship supplied an aesthetic and using expertise fairly not like anything available on the market:
“You may say the BMW’s secret was—and nonetheless is—a fragile steadiness, proper on the hyphen between ‘sport’ and ‘touring.’ The bike has barely rearset pegs and a low handlebar, nevertheless it places you in an all-day-comfortable ahead lean with first rate leg room and never an excessive amount of weight in your wrists…Nevertheless it isn’t simply consolation that invitations long-distance journey. The R90S, like most BMW boxer twins, has a well-earned status for reliability together with a easy and reassuring engine cadence that whispers into your helmet, ‘I can do that ceaselessly.’”
Our new pal Michael Ritzker — previously from Ontario and now a resident of Vancouver Island, British Columbia — definitely put his personal R90S to that take a look at. He purchased his ’76 from a vendor showroom in 1978 and set forth on the highway of journey:
“I rode it throughout Canada, departing on October 16, 1979, outrunning the snow. I rode it round Toronto within the winter and the cops pulled me over simply to speak to the nut on this bike. I used to be 22. I rode it dwelling throughout the States in the summertime of 1980; it was so sizzling that I developed a cooling system of leaping into ponds in my denims and jean jacket and using soaking moist till dry, about 45 minutes. “
After that pair of transcontinental rides, he bought the bike to a pal who let it rot for some 30 years. Michael purchased again his R90S and “went kinda overboard.” He labored out of his carport, dodging flying ants and chilly winters, and enlisted the assistance of trusted craftsmen to create the R90S road scrambler you see right here.
Whereas a scrambler may appear to be probably the most anticipated path for an R90S, Michael’s personal historical past with the bike speaks to its suitability for the position:
“After I rode the R90S again within the day, I generally would take it on grime roads and easy trails and it went together with aplomb, in order that figured into it as effectively. The present development for retro scramblers can be a pleasant sort of backdrop for this bike, as if to say, no, that is the way in which.”
We don’t wish to say an excessive amount of, as Michael’s personal story of his bike and construct is among the most entertaining tales we’ve learn in fairly a while. Suffice it to say, it generally appeared future or a better energy was at work within the course of…and generally not. Earlier than we hand over the reins to Michael, we’ll depart you with a few of our favourite phrases of knowledge from his story:
“Bikes are distinctive…in that they’re chosen for what emotional appreciation they generate, as an alternative of practicality and efficiency alone. However you can not have the previous with out the latter, that’s the trick.”
BMW R90S Avenue Scrambler: Within the Builder’s Phrases
Please inform us a bit about your self, your historical past with bikes, and your workshop.
I’m basically nonetheless a 15-year-old child who learn each bike journal there was throughout the late 60s and thru the 70s, and on, even till in the present day, considerably (therefore BikeBound). So my sensibilities have been shaped round The Ten Finest Bikes of 1975, or the then Cycle World annual Purchaser’s Information. Bikes like the assorted ultra-cool CCMs that have been featured, the Suzuki Titan successful greatest bike, the alluring Italian beauties and the trick Spanish purebreds — that type of factor. It wasn’t till my sixteenth birthday (1973) that I may get on a motorcycle; I signed up for the “British Columbia Security Counsel Rider Coaching Course” on the Delta B.C. airstrip, solely as a result of they’d bikes. I’d scream up and down the runway on the Kawasaki K100 as a result of it went the quickest. They solely had small bikes there. You could possibly additionally do your take a look at with them in your licence. I credit score this for making me a protected rider all these years.
Finally I had my very own bikes, starting with a clapped-out DT250, a brand new RD400, and this BMW R90S, simply because it was so fairly. It was in a vendor’s showroom. The store belonged to the quirky and irrepressible Phillip Funnell, with a membership foot who had toured the world aboard a BMW. The bike had been crashed and repaired however I didn’t care. It was repainted in an exquisite cobalt blue / silver smoke copy of the inventory sample by “Boots,” who was the customized man of the day. I rode it throughout Canada, departing on October 16, 1979, outrunning the snow. I rode it round Toronto within the winter and the cops pulled me over simply to speak to the nut on this bike. I used to be 22. I rode it dwelling throughout the States in the summertime of 1980; it was so sizzling that I developed a cooling system of leaping into ponds in my denims and jean jacket and using soaking moist till dry, about 45 minutes. I thereby found the way it was prefer to experience within a garments dryer.
I ultimately bought the R90S to a buddy and bought an R80GS the primary yr they got here out. After just a few years I traded that for a BSA B50MX (and money) that was licensed for the road. It seemed robust and went as quick because the BMW, up to some extent. It obtained me hooked on BSAs. I now have 5, together with a uncommon 1967 VGP, and a ’72 Rocket triple that I modified right into a Hurricane tribute. Through the years I developed numerous particular high-end abilities like fixing cantankerous BSAs on the roadside utilizing stuff I discovered mendacity round and what I introduced in my software package. I can do stuff like clear a carb jet, set factors, repair damaged brackets with wire and tape, and hint damaged wires. However that’s the extent of my abilities in that division. I may also clear elements, sand, buff, and paint. So I pay guys who know how you can assemble equipment and that type of factor. My fundamental expertise is my eye for cool-looking designs, which I attribute to the aforementioned magazines, of which at a critically impressionable age I learn a whole bunch, all of the completely different ones they’d again then, principally all gone now.
Why was this bike constructed?
About ten years in the past I purchased the R90s again from my buddy who had crashed it and let it rot for 30 plus years. So as an alternative of paying to revive it, and it wanted virtually all the things, it was in such poor form, I ultimately ended up going full rogue. The carbs had one way or the other fused themselves to the cylinders, and crumbled from the stress of attempting to dislodge them. The suspension was shot. There was rust contained in the engine, and so forth. So ultimately after some unintentional occasions I made a decision to take a valuable R90S and make it even sportier. I’m not gonna lie, I additionally loved the considered annoying the usual crowd who give likes to all the next R90S posts of their FB teams, even though every one among them are precisely the identical. My bike was going to be a lot better and really cool, that was the restricted extent at the moment of my imaginative and prescient.
I don’t have a workshop. I’ve a carport. So portray up right here in Canada is a seasonal affair. Finest to keep away from flying ant time in August, FYI. However I’ve realized the exhausting means about who will do an sincere job on the work I contract out, and after about six years of up and down outcomes, I lastly discovered the connections that helped me.
The primary mechanical man is a extremely expert Dutchman who was BMW manufacturing unit educated, now in his 50s, however sadly is also deeply infused with autistic tendencies, to the extent that once I first introduced him the bike 5 years in the past, it resulted in him disassembling it proper all the way down to the final washer. As a result of he discovered grime. Or rust. Or one thing. The charging system drawback I had initially wished him to repair was far down on his listing of priorities. So now the construct grew to become a bit extra complete, as, because it was now all in items, albeit properly organized in numerous tins, yogurt cups, and so forth, I made a decision to make one of the best of it — might as effectively put it again along with spirit.
Therefore the polished crank, all new bearings and seals, lightened flywheel, beefy u-joint, trendy upgraded charging elements, the Siebenrock 1 L package (must out-run all these requirements, proper?). Plus, since I do know that the legendary Kenny Roberts made the Lectron carbs well-known, as I had learn again then, so I needed to have them. They’re attractive, with the shiny shiny silver alloy and the clear floats and the flat-slide slimness, they appear pearl-handled six-gun severe. And so they work so effectively, no idle velocity / combination screws! The mechanic was barely baffled by that. However they certain make easy energy, the bike additional benefiting additionally from the fashionable light-weight pistons, and the right fueling. The Motogadget system Herbert Von Karajan type orchestrates all of it.
I’m a giant fan of the location VFT.org (Classic Flat Monitor), and from there I scored a Benelli Mohave NOS tank. You possibly can learn the break-in instruction sticker on this tank, which I initially purchased simply because it’s so uncommon and I preferred its form (the vendor thought it was a “Ducati or one thing”). You will note some very cool bikes and elements on VFT and the way in which that website is offered simply makes it appear as for those who can scent the bikes and gasoline and oil when you are there. So legit.
When it got here time to ascertain the search for the R90s, that tank hit the spot, as in the remainder was going to comply with. I used to be going to do one thing no one had carried out so far as I may see, and that was I used to be going to make use of an R90S to duplicate a type of 70s type scrambler, and imagine it or not, one among my fundamental influences was the Harley/Aermacchi Baja 100 scrambler — one of many coolest bikes I ever noticed. I’m an enormous fan of Italian motive design sensibilities, or ethos, or no matter it’s. The strains and proportions and textures are sometimes beautiful. Additionally, once I rode the R90S again within the day, I generally would take it on grime roads and easy trails and it went together with aplomb, in order that figured into it as effectively. The present development for retro scramblers can be a pleasant sort of backdrop for this bike, as if to say, no, that is the way in which.
This bike has a Ducati entrance finish off an 848 Monster, which I discovered from a salvage website. I actually didn’t know precisely what sort of Ducati it got here from till I needed to discover brake pads, and the thriller price me an incorrect buy and quite a few telephone calls, emailed pictures and so forth, till Island Ducati in Victoria B.C. had a mechanic with sufficient expertise to establish it (thanks!). The entrance finish was overhauled and lengthened by an ex-racer who ended up in a wheelchair after a motorbike race crash and remained hands-on bikes with a customized suspension store. Exceptional man.
The entrance wheel was a nightmare. I wished spokes on alloy rims, 21″ entrance tire, so I sourced a spoke hub off of a 1000 GT Ducati and tried to suit with that. Catastrophe, nothing lined up. I ended up with a customized machined-from-billet hub and an odd configuration the place the hub may be very slim and the rim is much away, so it resembles a bicycle wheel. Like the remainder of this construct it was a fluke that simply appeared to make it higher. This was now revealed to be an on-going theme as I started to note. A few of this construct was like following a imaginative and prescient quest, so much was sheer dumb luck, some not so good, however ultimately good.
The rear is a inventory hub mated to an alloy 19″ rim, all from Central Wheel within the UK. One of many few simple sections of the construct. As have been the Öhlins shocks, which have been made for this mannequin. One other fluky consequence was that the black anodized spokes have fairly large-ish shiny stainless silver nipples, which in opposition to the black anodized rims and spokes give a powerful distinction and a jewel-like impact.
Dumb luck strikes once more, identical to the paint on the body which is one other catastrophe that turned out stellar. What occurred is that I watched too many Youtube movies and created a hodgepodge with silver metallic, silver flake, Dodge B5 blue (God’s Cobalt) and Rat Fink sweet gold. All rattle-can. It was all going alongside okay till I offered the gold sweet a little bit an excessive amount of, as in hardly in any respect, and now a lot of my blue was extra inexperienced than I had wished. However Youtube taught me how to do that loopy darkish ghost impact on high so I used to be not too involved, because the preliminary thought was a sort of black with hidden hues.
Nevertheless, the ghost was truly an evil spirit and a cataclysmic battle erupted. All of the paint started to seeth and squirm, and ultimately settled right into a weird electrified crackle motif the place each component was randomly expressed all through the body. I let it treatment, afraid to disturb it lest the battle escape once more, nevertheless it settled down and took the clear coat passively. I buffed and polished it and now I’ve witnessed that it reacts to daylight as if blessed by a benevolent paint God. Portray is a really non secular expertise, so I’ve realized. Painfully sure. However generally I’m rewarded in trusting in a better energy.
Due to one other of my obsessions from my early life, with the mythic Maico Sq. Barrel 501, the fenders and seat appeared. I don’t take into account anybody who shouldn’t be impressed with that bike, the profile, the inherent brute menace, as ever being able to actually being moved by something. Somebody as soon as stated of the 501 that it actually had no motive for present, so that’s exactly why it made its technique to my bike, which could appeal to the identical commentary. However Airtech is aware of. And so they made the fenders for me in carbon fibre.
I sourced a seat pan and foam from DC Plastics, who’ve the great sense to make them, nevertheless it wanted some trim and re-shape to suit the body and tank, however not a lot. To get it blacker than black, I used suede. An area upholstery tradesman by the identify of Chuck Constable put all of it properly collectively, together with the tank fitment. That is yet one more instance of a random affiliation I made in choosing these items. However subconsciously, the work was being attended to, because the shapes all appeared to draw each other, like the ultimate scene from “The Iron Large.”
One factor for certain is that I knew precisely what I didn’t need. I dislike the BMW inventory tanks, (all besides the toaster type, in Dodge B3 blue, ideally.) Bing CV carbs, no. They’re the smart orthopedic footwear of carburetors. Any saveable weight — gone. I used titanium or nylon fasteners all through. Antigravity LiPo battery, which loves its dwelling within the former air field. Positive, the Mohave tank is metal, however it’s smaller than inventory, and is Italian metal, which is quicker.
The tail mild weighs a couple of gram. It’s by Kellerman and it’s possessed with irrational brightness. The R90S was mild to start with, the body noticeably so, as a result of I used to be going to make use of a later mannequin single-shock body at one level, however observed it was far heavier than the R90S, which had residual crash injury from lengthy way back. It was repaired by an knowledgeable welder from the Australian Outback, the place repairs go to reside lengthy and prosper, and whose eyesight collapsed quickly afterward. Discuss unhealthy and good luck. However general, my concentrate on making the bike lighter, sportier, sooner, sexier aka extra Italian, was paying off. The headlight is from Australia’s Goal Constructed Moto and it compliments the opposite components, abrupt, all enterprise, however sparse and slick. As are the indications from Kellerman.
The inventory R90S handlebars, so pretty and ideal, they needed to stay, however they required slight lengthening to suit the controls, that are Thomaselli and Magura. Darren Church buildings, (a kidney transplant survivor following 10 years on dialysis) who’s an Englishman and journeyman mechanic, whom I recruited from our native Sunday morning espresso rider congregation, took on a thousand small jobs to suit all of it collectively, together with widening the bars.
Plus an epic expertise with Flanders Co., who constructed the gorgeous race-spec, cut up throttle cables. I made a decision to verify of fitment and size, and so I despatched one carb and the Thomaselli throttle all the way down to them in California, however the postal system appeared to have eaten the mission on the way in which down, and on the way in which again, disgorging it solely after digesting for over 4 months. The cables, in spite of everything that, turned out to be a couple of awful 2 mm too quick, so Darren needed to be taught cable soldering. In fact he did.
I discovered an OEM rubber entrance fender mounting gasket on eBay, which was uneventful however nonetheless wholly satisfying. You possibly can’t see it however I warrant that it’s there. My pal Invoice Beekman gave me the complete stainless Supertrapp system, simply because it was mendacity round in his good tidy, retired plane mechanic’s store, and he loves bikes, and builds 1920’s Indian Scouts. You already know, that sort of man.
I painted the fenders, which as I stated got here from Airtech in an exquisite carbon fibre clear coat, regardless of the opportunity of demonic interference. I candied them with, you guessed it, Dodge B5 blue sweet rattle can and re-cleared them. It produced a beautiful clear blue hue upon the carbon fibre seen beneath, so I’m significantly pleased with that and the great fortune of no flying ants that day or two, or three. Loads of buffing and sharpening ensued and I solely dropped one as soon as, to no nice disastrous impact, such that one other spritz of two-part rattle-can clear coat couldn’t repair.
I’m additionally pleased with the way in which we eradicated the engine air consumption castings, which developed by one among innumerable conversations I had with Darren (the bike was not in-built my carport, however in Darren’s little Englishman-sized work-shed). I despatched the airbox circumstances to a retired 83-year-old pulp mill machinist in Crofton B.C. named Bob Higgins who has a store in his home. I knew he was the best man since you may eat off the ground of his store, it was so effectively rigged. He shaved them down, made the plates and holes and wire mesh for them.
I employed my distinctive high-end abilities by making use of a mix of outdated paint and used engine oil to soiled them as much as match the remainder of the engine. I had beforehand concocted a vile mixture of gear which gave the opposite numerous engine coverings an “enhanced” patina as an alternative of the Fb lovers’ desire for vapour-blasting perfection. It is a secret proprietary method, which I most likely may by no means replicate in any occasion, identical to most of this bike. The result’s beautiful, I imagine, in that the strains of the engine circumstances are thus improved with the elimination of the air ducts. No one else has tried this so far as I do know. Credit score to Darren for saying “nice thought!”
So to sum up the design plan (which is non-existent), this bike is a product of my creativeness, the just about random involvement and contribution of some very attention-grabbing folks and experiences, and coincidence. However — was it truly coincidence? Or was it future — that some 50 years after some child from the suburbs developed lifetime obsessions with the aesthetics of bike kind, design, and the particular coolness of bikes the-likes-of-which we are going to by no means see once more, randomly assembled this bike? Or is that this bike simply a solution to a query which no one requested?
Are you able to inform us what it’s prefer to experience the finished bike?
Remarkably easy, agile, fast, handles nice. Steady. Spectacular sound, not too loud, however racy. The primary impression nonetheless revolves across the shocking results of how all these pretty disparate components so cohesively managed to mix right into a strong experience. Built-in, I suppose. The tires are Bates Baja, so that could be a very apt connection to the Harley Baja, plus they’re nice tires.
The suspension and brakes are particularly spectacular, and are an entire success. I’ve owned many bikes because the authentic R90S, together with a KTM 950 Journey. After that one, I made a decision that trendy brakes and suspension have been crucial, so I’ve integrated them on the bikes I’ve constructed, because the trendy entrance ends in my view truly look nice on traditional bikes. One axiom about motorbike design is that you just can not spoil a glance with beefy entrance ends (hi there Harley), you simply can’t. However wimpy spindly ones look crummy. That’s my view.
Additionally, trendy electrics are an crucial which I’ve accepted resulting from my numerous forays dwelling behind a sketchy BSA headlight, that’s, if the bike truly determined to start out. The R90S begins and idles simple, it has no flat spots. The lights and indicators perform to an virtually extreme diploma. The swap buttons resemble to me the ornaments on the wrists of a fairly girl. The bike, like once I first noticed it so way back, is simply very fairly, and that’s vital to me.
Bikes are distinctive in that respect, in that they’re chosen for what emotional appreciation they generate, as an alternative of practicality and efficiency alone. However you can not have the previous with out the latter, that’s the trick.
It happens to me that the crew of misfits who contributed, with all their numerous illnesses, setbacks and challenges, had in a way helped to realize an occasion of “perfection” whereas transcending their very own imperfect selves. I suppose that to be related to the emotional issue and the ability of aesthetics.
