The Bimota YB9 was a in-line four, four-stroke sport motorcycle produced between 1996 and 1998. It could reach a top speed of 155 mph (250 km/h). Max torque was 49.42 ft/lbs (67.0 Nm) @ 10000 RPM. Claimed horsepower was 103.8 HP (77.4 KW) @ 12500 RPM.
Overview
The “9” has nothing to do with the bike’s displacement and simply indicates that it’s the ninth Bimota powered by a Yamaha engine. It’s a bit down on power compared to its stablemates the SB6 and the YB11, which feature the Suzuki GSX-R1100 and Yamaha YZF1000R “Thunderace,” respectively, since the YB9 actually uses the liquid-cooled inline four and transmission from the YZF600R “Thundercat” with around 100hp and it even uses that bike’s stock gauge cluster, nestled in between the carbon air-intake tubes.
Bimota obviously made its reputation wrapping lightweight frames and sexy bodywork around reliable powerplants from Japan, sexy powerplants from Ducati, and even the occasional German powerplant from BMW… Their early offerings used tube-style frames, but by the 1990s they’d moved on to aluminum beam frames as seen here. Access on some beam-frame models for maintenance and repair can be a bit iffy: the massive-looking part used on the Bimota SB6 and SB6R is designed to connect the steering head and swingarm pivot directly, but makes access to some parts difficult, like the front sprocket that supposedly requires the engine to be dropped when it needs changing… I’ve heard no such complaints about the YB11 that uses a very similar frame to the one seen here, which makes a certain amount of sense considering the fact that both use Yamaha engines. They also produced an SRi model which was fuel injected compared to the carbureted SR model. Just 651 YB9s were built.
