Bimota SB8R Special
Is that Bimota's new model , the one they've been talking about in my local café" ? asked the toll collector at the Rimini Nord autostrada exit as he leaned out of his booth to get a closer look while I fumbled for some change . "It looks pretty fast , and judging by how long this ticket tells me it's taken you to get here from Pesaro , it obviously is - very ! That Ducati engine inside has molto grinta (lots of poke) and it sounds like nothing else on two wheels . The Japanese couldn't make a bike like this , could they - eh!" . For this here is the SB8R , and not only is it the first time anyone outside Bimota has ever ridden it in real world conditions out on the street , it is also - how can I tell you this - an Italian bike with a Japanese heart . Because the SB8R is powered by not a Ducati desmoquattro but by Suzuki's TL1000R engine , the 90 degree V twin Superbike motor that the Japanese company launched alongside it's similarly fuel injected four cylinder GSX-R750 barely a year ago , but in which it now seems to have lost interest after just a single season . That makes the SB8R a haichi balbu eight valver instead of an otto valvole . And as far as Tognon is concerned , Suzuki gave him the handsome present of a leading edge engine design that will allow him not only to bring Bimota back to the World Superbike arena in 2000 but also to rebuild the company the same way it built its prestige the first time around , before the 500 Vdue two stroke troubles sent it off the rails over the last five years . They wont have another chance - and nobody knows this better than its new owner . That's why the customer SB8R's long awaited arrival in Bimota dealership has taken so long , as Tognon's R & D team under new chief designer Francesco Medici has worked had and long to refine the new bike with an attention to detail that no other Bimota model has ever had before . This one has to be right - and from day one at that . Fortunately , my 200 mile day trip from Rimini factory out into the hills of central Italy came up with the right answers . This is a very good motorcycle , and I defy anyone to test the SB8R back to back with a TL1000R and avoiding concluding that this is the V twin sports bike that Suzuki should have made but couldn't or just plain didn't . Because what is on offer here with the SB8R , apart from being the first road bike to feature a carbon fibre composite chassis , is a $23,595 entry ticket to the same kind of no compromise race track technology for the street that Yamaha's even more costly R7 delivers . This frame uses vacuum sealed carbon fibre lower frame spars keyed into the fabricated alloy uppers to increase front weight bias as well as a self supporting carbon sub frame for the seat (just like on Aprilia's World Champion GP racers) . Then there's the engine . Bimota has improved performance from the 90 degree V twin engine via Magneti Marelli EFI , with a single high pressure injector per cylinder , that's part of a system that replaces the TL1000R's stock Japanese engine management system and is equipped with massive 59mm throttle bodies (up from 52mm on the TL1000R) made in house at Bimota . It should be a potent challenger to it's Ducati and Aprilia rivals as the chequebook choice of the twin cylinder tifoso . The result is not just an after market kit part look at odds with the presumed objective of this costly , limited edition (350 bikes in the first '99 year batch) motorcycle , but the black muso (nose fairing) combines with the TL1000R headlamp and large , matched air ducts to create what appears to be a rather wide bike for a V twin . At first sight , it makes it seem a pity that Bimota wasn't able to avoid falling into the same trap that Suzuki did in making a V twin that's as wide as a four . But throw a leg over the Esse Bi Otto , and those first impressions are shown to be false . The Bimota does push a lot of frontal air , necessitated mainly by the KTM made radiators as well as the ram air ducting to those big throttle bodies , so that the view from the bridge is dominated by the big twin carbon fibre air ducts leading to the voluminous airbox between the cylinders . Though large , the air ducts stop seeming intrusive after a few miles , by which time you've also gotten used to operating the switch gear by feel , since the ducts obscure them from your view . Nevertheless , the SB8R feels slim to sit on , with your knees tucked into the flanks of the sculptured fuel tank . It is also agile and responsive to steer , and as nimble as any Superbike when you chuck it through twisting mountain passes or winding cliff top roads . And that's with the adjustable steering geometry dialled in using the most conservative settings , with 24 degrees of head angle rather than 23 and 93mm of trail instead of 87mm . The more radical settings make the bike race track friendly . Yet there a relatively spacious riding position that will suit taller customers , in spite of it's short (for a V twin) 54.7 inch wheelbase , and surprisingly low footpegs that somehow do not compromise Ground Clearance . And my run down the Pesaro autostrada was to show , the biota is a practical road bike that's extremely aerodynamic (even if the mirrors are half useless at any speed) , with such good penetration and rider protection from the pointy screen fairing that I had to do a double take at the Suzuki speedo to be certain I really was travelling at 160 mph - in fifth gear ! It did not seem like it even when I hit the 11500 rpm rev. limiter , which was a good time to hit another gear and discover this is an effortless speed capsule with a top speed of what I'd guess is around 175 mph (there were too many Greek truckies racing each other to the Brindisi ferry to find out) . Yet which is happy to sit at 150 mph in top gear for as long as the traffic will let you , with the tacho needle parked on the nine grand mark . All this in spite of not having seen the inside of a wind tunnel . Two things impress about the Bimota , as it delivers this A grade (as in autobahn quality) performance , the muscular , meaty lilt of the off beat exhaust note issuing through the arrow silencers , which will not just have tollgate attendants confusing it with a Ducati , and it's superb stability at high speeds , coupled with fine ride quality and good suspension compliance from the fully adjustable 46mm Paioli upside down fork and ditto ?hlins rear shock . The shocks placement is novel , as it is set up high and forward , and operated by a long rod directly off the asymmetrical alloy swingarm .
Yet it is also a very light one by the standards of the class , with the Bimota's claimed dry weight of 387 pounds a whopping 46 pounds lighter than the TL1000R in spite of sharing the same 130 pound engine . You feel the benefits of this in the way the SB8R can be chucked around almost on autopilot . And for an extra 3 million lira you can have the SB8R special , available only in black , that saves another couple of pounds that s to the use of assorted extra carbon fibre and aircraft alloy hardware .
And on fast corners , well , you just pick a line and know the bimota will hold it . There's absolutely no power understeer , no deflection from bumps and loads of Ground Clearance - nothing drags . This bike is a lot of fun to ride hard . It stops well too . The big brakes are Brembo's best , with loads of bite giving a huge amount of stopping power , coupled with a high degree of sensitivity . And when you trail brake into a turn , the Bimota holds it's line , even if you overdo the entry speed and have to grab a bigger handful , it does not sit up and understeer away , in spite of the fairly radical geometry . Totally sorted . And that's without fitting any of the trick race parts obtainable directly from Suzuki or Bimota's own promised aftermarket kits ,which should raise output to 160 bhp or more . And once motoring , the Bimota's TL engine has an extra kick at 7000 rpm , when the rasp from the exhaust - slightly higher pitched than a Ducati - hardens , and the engine heads determinly towards the rev. limiter . The only glitch is a slight hesitation if you roll it on hard below 5000 rpm But if you want to just lope along in traffic , the engine's quite happy ticking over at 2500 rpm in fourth gear , ready to come on strong when a gap appears - pickup is strong after the initial stutter .
