Description

This is my beautiful little Bimota YB7. Only 320 units made for the world wide market it is believed that less than 20 were delivered to the United States making this a very rare jewel. Most of the production went to Japan where the 400cc motor capacity was the largest bike you could ride at the time. This is a wicked cool little bike. It features thehand welded huge aluminum beam frame that Bimota is known for as well as the top quality Marzoochi/Ohlins suspension, assive Brembo brakes and Bimota spec OSCAM wheels. Fo power you got a screaming 14,000rpm Yamaha FZR400SPpower plant. Cool thing about this bike is you can sit on it and touch the ground flat footed if you are under 5'5". My wife and daughter both rode this with no problem. I'm 5'11" and it fit me perfectly. It's so dam light at about 325lbs. It flicks from side to side so quickly its amazing. Probably the most fun bike to ride in my whole collection. This particular bike came to me a few years back from it's first owner. It's inreal nice condition. It has not ever been crashed but a couple scratched on the left side motor cover and the bar end say it did fall over once. That is more than likely due to the suicide Ducati styleretracing side stand. (stupid design!) Anyway the bodywork is very nice with no breaks it has a few stress cracks but certainly completely showable. I would rate it a 8 out of 10. Not museum quality like my other listed Bimota's but very very nice. This bike was recently serviced and runs perfect. The battery is still good in it. Wit the low miles and real life fun to use factors this is a must for amy Bimota collector or someone who wants a amazing little bike that No One else has at thew Rock Store, lices' or Marcus Dairy! I can help ship thisbike but it is the buyersresponsibility for all expenses. I have a special deal with Daily Direct and I can get it to your home anywhere in the United States for $500 or less.

Thanks for looking!Pete

160/60-17Considering how important the Japanese market has been not only in Bimota's recovery from bankruptcy, ut also their long-term profitability (over 50% of their annual production goes out East) you might wonder why it has taken so long to make a bike like the new YB7. Conceived as a direct response to the Japanese Importers request for a baby Bimota with sub 400cc engine but with all the allure of bigger Bim's, he FZR400 Yamaha powered YB7 is a perfectly scaled down replica of the bigger YB4 and YB6 road burners, own to identical paint job and replica racer styling based on the YB4EI racer that so nearly won the inaugural World Superbike title.

As such the YB7 slots into a unique marketing niche, ne that is likely to remain the sole occupier of for some time now that Ducati's proposed 400cc eight valve V twin has been sidelined, or the time being at least. In other words, t is an expensive, igh tech. European roadster with race bred handling and Italian flair, onceived in order to the vital Japanese markets 400cc class table in terms of price and exclusivity.

All the first batch of 160 machines currently being built in Italy are destined for Japanese customers, ho either don't want, ant afford, ren't licensed or cant get insurance for the regular Bimota range of 750/1000cc machines. But in the case the idea of a baby Bimota appeals to anyone living outside of Japan, hink again - at least for the time being.

This is the first Bimota for nigh on a decade designed and built on commission (though of course that is how they started out in the seventies, uilding one off frames to house almost any engine the customer wanted), nd the Japanese importers have the exclusive on it till their market is satisfied, ot to say exhausted.

Only at that stage are Bimota free to sell any bikes remaining from the projected 500-unit production run elsewhere. So my day excursion into the Italian countryside on the YB7 prototype was a taste of forbidden fruit for those of us outside Japan (well just about any Bimota is, iven the number of zero's at the end of the rice tag). But the more I rode this exquisite motorcycle, he more I became convinced that it should be sold elsewhere, nd that bikes like this really do have validity on non Japanese roads and away from their massively competitive F3 racing class - for which the YB7, y the way, s ideally suited. I ended up rather glad that I'd been obliged to miss the press launch at the Vallelunga race track a couple of weeks beforehand through injury,

because other wise I'd never have had the chance to ride the YB7 on normal roads in everyday traffic - for which, nlike almost any other Bimota ever made, ts perfectly suited. Riding the YB4 or YB6 in town or from one traffic light to another along the traffic clogged Via Emilia, s like going shopping with a Porsche 956 or going for a trot on a Derby winner - not really what it was developed for. A bike that can break the speed limit in bottom gear acts like a thoroughbred racehorse, training at the reins and urging to break loose.

When you are out in the open and can give it is head, hen it comes into its own, ut then lets face it Bimota's aren't meant for commuting, ll except the YB7 that is. Apart from the serious lack of anywhere to strap a tank bag or briefcase (designer knapsack anyone?), his could be the ultimate Yuppie bike of the 90's. Just the thing to roll up to that business meeting on, hen the weather is dry enough to leave the BMW 325 in the garage and venture out on the Bimota to cause a bit of a stir. At low speeds the Yb7 is docile, ractable and well balanced, deal for pottering through traffic on and not even too uncomfortable, hanks to the low seat height and relatively high set handlebars.

To my surprise, t may look a small bike when you see it parked next to something else, ut it does not feel small or cramped to sit on, ven for someone of my height. But it does feel light, esponsive and easy steering, oth at low speeds and somewhat faster. But when the road opens out and the traffic lights thin, he YB7 will display all the legendary poise and sure footedness of its bigger brothers, et with one vital difference - that incredible evocative little engine. I admit it I've never ridden a road bike with a 14,000rpm redline before, or one that positively sends shivers down your spine from the howl of the four in one, xup equipped exhaust as you nail the throttle wide open and watch the rev counter needle rocket effortlessly into five figures.

The 56 x 40.5 mm, our valves per cylinder engine is fitted to the YB7 in standard form as received from Yamaha, part from the addition of a Bimota silencer and air filter, nd some re jetting of the four 32mm downdraught Mikuni carbs to compensate. These alterations raise the output on Bimota's dyno to 68hp at 13,000rpm (2hp more than the standard set up gives, ccording to Bimota chief designer Federico Martini, hough Yamaha rather surprisingly claim only 60hp at 12,000rpm for the stock FZR400), hich combined with a dry weight of 352lbs is quite enough to give exciting performance, s opposed to the frightening type that the YB4/YB6 can deliver if you are not careful with your right hand.

But on the YB7 you can wind the engine up to the redline in every gear, r else change up at the five figure mark and let the extra torque on offer (thanks to the computer controlled EXUP exhaust power valve, ocated in a painted aluminium box just where the four Yamaha headers meet the single Bimota tailpipe) pull you through to the next gear. With a top speed of 136mph the little bike has the performance of a 600, et the docility of a 400, oupled with the peerless handling of a Bimota chassis. This is a slightly downsized version of the YB4/YB6 design, till made from Anticordal aircraft alloy, rom which the in line engine is under slung, ith the cylinders inclined at 45 degrees.

The wheelbase of 54 inches is 2 inches shorter than the YB4/YB6, nd with ahead angle of 23 degrees (static, ully extended) and only 97mm of trail (compared to 24 degrees / 105mm on the bigger bikes), his is bound to be exactly what it is - a nimble, ltra fast steering little bike that nevertheless gives the feeling of controllability you might not expect after reading those figures.

The 17 inch wheels shod front and rear with Michelin's new Hi Sport radials (though I wouldn't care to ride very far on the rear one in rain on a bike whose fibreglass costs as much as Bimota's) probably help in eradicating the unstable steering of Bimota's last little bike the DB1S with its 16 inch hoops. Much to my surprise, he only word I can find to describe the Marzocchi front forks is "Superb". Matched with the Ohlin's rear unit, hey gave really good handling over some very bumpy roads up in the hills behind Rimini, ever bottoming out or juddering as the M1R's have been known to do on other bikes, nd making the little YB7 a truly pleasurable companion over all kinds of terrain. It really is a useable, ulti purpose mini Superbike, ore so than any other Bimota ever. Beneath the fibreglass shroud is the plastic fuel tank, hence fuel is pumped electronically to the carbs just as the FZR400. The fuel warning light is actually the also the reserve switch, ounted on the dashboard which you punch as soon as it starts to glow. Too bad Martini omitted to warn me of the neat and vital wheeze.

Never mind it was not a long push. I suspect we will be seeing the YB7 Bimota in circulation in Europe rather sooner than many people expect, ut not on the street. For some time now the Japanese factories, specially Honda, ave been pushing the FIM to adopt the Formula 3 class that is so popular in Japan for Worldwide application- and not only at the Isle of man TT, hich is after all where the idea of a formula matching street derived 400cc four strokes against 250cc two strokes was first dreamt up. With spiraling costs and slimmed down fields resulting there from in the European Championships, specially the 500cc class, here's a good chance that the F3 category may come to Europe in a big way in 1990. When that happens, imota will be ready - but in the meantime "La Piccolina" (the little girl), s everyone in the factory calls the YB7, s strictly for Oriental consumption only, hat a shame.
