You would need to have been a diehard fan of mid-to-late ‘90s AMA Superbike racing to recollect Harley-Davidson’s VR1000 Superbike. There are a selection of causes for that, however the actuality is that after Father Time marches on, individuals don’t keep in mind who completed second or third; racing followers solely keep in mind the winners and champions. As Ricky Bobby stated in Talladega Nights, “When you ain’t first, you’re final.”
Sadly for the sake of historical past, the dearth of success that the VR1000 achieved, and the huge quantities of cash that have been poured into the venture, imply that The Motor Firm itself has largely tried to neglect concerning the bike’s legacy by quietly sweeping it beneath the rug. In that regard it positively got here in “final.” And the truth that solely the minimal variety of 50 homologation bikes have been ever constructed, and weirdly registered in Poland, implies that seeing one in particular person is akin to seeing Bigfoot. Really, we’re fairly certain there are much more experiences of the latter than the VR.c
I usually surprise if this was additional exacerbated by the truth that as one of many largest motorbike corporations on the planet, H-D had little to indicate for its efforts, whereas at roughly the identical time John Britten and his tiny crew not solely constructed their very own motorbike from scratch (in a New Zealand storage workshop), they then principally cleaned up in many of the races they have been eligible to compete in on the Britten V1000. There are eerily fairly a couple of similarities between Harley’s VR1000, and Britten’s V1000. Each featured 60-degree DOHC eight-valve V-twins with digital gas injection. At a time when such gas supply was simply beginning to be thought of by motorbike producers for manufacturing (Honda’s NR750 and Yamaha’s GTS1000 to call a couple of).
The fact is that the VR1000 was all however forgettable as a racing machine. How else are you able to clarify the truth that Harley employed the perfect of the most effective racers of the period, after which managed to fade into historical past with no single win.
Excessive-profile riders who piloted the VR throughout this system’s existence included Miguel Duhamel, who’s credited with 86 AMA Nationwide wins together with titles in Superbike (1), 600 Supersport (2x), System Xtreme (2x), and 5 Daytona 200 wins. He was adopted by Scott Russell who additionally gained 5 Daytona 200s, the 1992 AMA Superbike title, and the 1993 World Superbike title. Whereas three-time AMA Superbike champ Doug Chandler rode the bike for a single winless season in 1995. All three of these riders had additionally hung out contesting the 500cc Grand Prix collection in Europe.
Harley’s longest-serving rider was former AMA Professional Twins champion and AMA Superbike race winner Canadian Pascal Picotte. He rode the VR1000 for 4 seasons, finally scoring a pair of podiums in 1999. One other massive title to sit down within the H-D’s saddle was seven-time AMA Grand Nationwide Flat Monitor champion Chris Carr. He discovered restricted success, however took the AMA Superbike Rookie of the 12 months title in 1995, earned a pole place, and had a high 5 end the next yr. Clearly the expertise within the seat wasn’t accountable.
Again within the March 1994 concern of Cycle World, our tech guru Kevin Cameron penned a characteristic titled “America’s Superbike,” through which he took a deep dive into the VR1000. He was granted unique entry to the bike’s first check at Grattan Raceway, the place check rider and former AMA 883 roadracing champ Scott Zampach threw a leg over the bike for the primary time, previous to Duhamel getting an opportunity to check out his new machine.
On the time, after years of preliminary engine improvement, it was time to truly put the bike on observe and begin the method of refinement previous to attempting on the Daytona 200 and the AMA Superbike Championship. The intent of the venture was to construct an all-American racer with sourced elements coming solely from the US when attainable. From Cameron’s story: “The machine has US-made Wilwood calipers and discs. On the entrance, a machine-sculptured Penske inverted fork. The dual-beam body is easy, direct—and US-made. The heads disappear up beneath the black gas tank, and I do know there’s a twin-bore Weber-USA fuel-injection throttle physique beneath there.
“From the head-gasket surfaces downward, the VR is the work of H-D employees engineers. The heads initially have been farmed out to Jack Roush’s consulting agency, well-known for its NASCAR connections. Steve Scheibe was a Roush worker till two years in the past, when he moved to Harley to turn into racing supervisor. He’s chargeable for the adjustments since then—the redesigned cylinder heads, the lighter chassis, the brand new gearbox, the chassis, the works.”
Bore and stroke for the VR measured 98 x 66mm, it used titanium Carillo rods which have been positioned aspect by aspect on the one crankpin. The crank itself utilized curler bearings whereas the rods used plain bearings. Cast three-ring Wiseco pistons have been used and sat in Nikasil-lined cylinders. The compression ratio was 12.0:1. As talked about, Weber-USA gas injection was used with a single injector per cylinder. Cameron provides: “Proper now, the VR has dirt-track energy traits; peak torque comes comparatively early, adopted by a large area of almost fixed horsepower.”
Greater than a yr into the VR’s racing profession, success had but to return, and all indications pointed to the truth that the bike was approach down on energy in comparison with the competitors from the likes of Ducati and Kawasaki. Particularly its high velocity. “At Brainerd final yr, Scheibe reckons it was 6 mph on high,” Cameron stated within the August 1995 concern of Cycle World. “At Daytona this yr it was extra like 10 mph. Energy requirement rises roughly with the dice of velocity, so this interprets to between an 11 and 20 p.c energy distinction. If the highest Superbikes make 140 or so rear-wheel horsepower, this may be 15–28 horsepower. That will put the VR down at 112–125, rear-wheel.”
Cameron continued: “All that is very perplexing, as a result of the VR has, bodily, all of the makings of success. It has a chassis of excellent stiffness, whose dealing with has been praised by everybody who has ridden it. It has the total 1,000cc that the foundations enable, with confirmed mechanical energy to achieve aggressive rpm within the 11,000 vary. The engine is a compact, inflexible design that matches a race chassis higher than the wide-Vee Ducati engine. Above all, it’s backed by a affluent firm with the means to fund quick, efficient improvement.
“The place’s the meat?
“Okay, how a lot beef ought to there be? We are able to estimate this by utilizing the engine’s rpm functionality, its displacement and generally attained averaged combustion strain. After we put within the numbers, we discover that there was nothing flawed with Jerry Department’s [airflow specialist who worked on the design early on] preliminary 1987 estimate that an engine of this kind may make 165 horsepower. And if the stroke have been shortened in F-1 GP fashion to boost revs into the twilight zone, this expectation may rise to the neighborhood of 180 horsepower. These are crankshaft horsepower, so subtract 10 p.c or so for transmission loss—160 and 180 then turn into 144 and 162 rear-wheel prancers. That’s beef, all proper, however imaginary.”
Wanting on the output from the aforementioned and really related Britten V1000, John Britten’s machine produced a formidable 170 hp. It’s additionally vital to notice that Britten had far much less assets at his disposal. Making the New Zealand–constructed machines all that extra spectacular.
Just like the engine, the twin-beam aluminum chassis was American made by a store in Portland, Oregon. The swingarm pivot had adjustable inserts to change geometry. Initially, the primary variations of the bike have been fitted with American-made Penske shocks and gas-pressurized forks, however by the point they lined up for the Daytona 200 in 1994, it was fitted with Öhlins suspension. Later down the street, when Russell and Picotte have been on the bike, the VR had moved on to Showa models entrance and rear. Out the door went the all-US-made mantra. If you wish to try and win in an area as aggressive as Superbike racing, it’s important to supply elements with a confirmed observe file.
Just like the suspension, the unique braking setup didn’t final very lengthy. Initially, the VR was fitted with the American-made Wilwood six-piston calipers, however in a while used Japanese-made Nissin six-piston equipment, and likewise at factors AP Racing six-piston calipers. Because the bike developed, so did the polish of the bike. Lovely machined rearsets, appeared extra akin to models off of a Bimota, whereas ample use of carbon fiber fashioned the sprint and housed the shows.
However all of this meant little because the bike couldn’t carry out the one activity it was assigned, profitable races. Sadly even way back to 1995, a full 5 years earlier than the venture was canned, the writing was on the wall.
In Cameron’s 1995 article, he wrapped it up saying: “So, what can we conclude? Is VR success simply across the nook? Most likely not. Is it coming, slowly however certainly? The observe outcomes say no once more, however Steve Scheibe believes the VR is seen inside the corporate as being on-track, making passable progress. Seething discontents, if any? Take your choose. Racing is engaging, so individuals wish to be a part of it. As a venture grows, some concepts are chosen, others are dropped. Egos swell and shrink. Turf is claimed, and fought over. There are inner winners and losers. Cash needs to be accounted for. Sturdy emotions reverberate, then turn into coverage. The customary thick layer of PR Bondo is troweled on in hopes of creating the human drama look as well-controlled as a studio picture shoot. It by no means does.”
Wanting again now, Cameron was appropriate. The VR1000 venture was at all times a couple of too many steps behind, and the group regardless of all their appreciable efforts and high-profile riders simply couldn’t discover the magic steadiness to make the bike succeed. By the early 2000s, with the bike out of the highlight, the VR quietly pale away from most followers’ recollections. Winless. However its unicorn standing positively earns it a spot among the many Coolest Sportbikes of the ‘90s.
