Only rarely seen outside Japan, the market for which it was exclusively designed, the Bimota YB7 is like a 3/4 scale YB4. The bike is based around the FZR400 powerplant, so it's obviously no real powerhouse, with a claimed 65hp from the 399cc liquid-cooled four. But that just means you get a sweet-handling, four-cylinder exotic with performance you can actually access, seeing redline in multiple gears, instead of just first, without finding yourself in the pokey.
And weighing in at 352lbs dry, it's not like the bike is actually slow: 136mph is plenty to have fun with, and the bike has a reputation for being relatively easy to ride and unintimidating as well, even in everyday traffic.
They're very rare as well, with less than 500 produced and, being Bimota, they're certainly collectible. So these fill a bit of a weird niche: an everyday exotic that won't try and kill you. For me, that's a big plus but, for many speed-junkies, anything less than 750cc's is a complete waste of time.
From the original eBay listing: 1988 Bimota YB7 for Sale
Located in Santa Ana, California. Bike has 5951 km = 3570 miles on it. This Bimota is based on the Yamaha FZR400. These bikes were built for the Japanese market only. Bimota made approx. 321 of these bikes. This bike is in very good condition with low miles. The engine runs very good. There is no crash damage on this bike. I do not have a title for this bike. Bike is being sold with a bill of sale only. Non USA buyers will have to make there own shipping arrangements. I can recommend a very good shipping company in Los Angeles. Bike is being sold as is, no returns. So, ask questions and look at the pictures carefully before you bid. Again, this bike is being sold with a bill of sale only. I do not have a title for this bike.
The seller mentions that he doesn't have a title for this bike, so be sure to check with your DMV if you plan to register it for the road. Caveat emptor: in some states, this will definitely cause headaches, although it may be no problem at all in others.
That being said, it's a really cool little bike that has, so far, generated very little interest. Which is a shame: parts to maintain it should be easy to come by, even if fairing panels are not, and the bike will provide more capability than probably 90% of riders can actually exploit.
If you could locate some pattern bodywork, it might make a very cool little racebike or track-day curiosity. Certainly, it'd be satisfying to run down literbikes and even 600's on a screaming little 400...
