Rider Profile

Best ForThis is a boutique exotic sportbike best suited to experienced riders who already understand aggressive, race-bred handling.
PurposeBuilt as a light, high-performance canyon-carving and track-day machine derived from a supersport donor engine, not a commuter or all-rounder.
Rider FitThe low, forward-leaning riding position and tall, firm seat demand a fit, flexible rider comfortable with wrist and back load.
CharacterA rare, hand-built Italian special with razor-sharp steering and a high-revving four-cylinder heart, rewarding precise, committed inputs.
Not Ideal ForNot a good fit for new riders, tall touring distances, passengers, or anyone wanting plush comfort and low-maintenance ownership.

1998 Bimota YB9 SRI Rider Ergonomics Assessment

Calculated in your browser only - your height/inseam are never sent to our servers.

Feet:

At 810mm, a rider of 175cm with a 79cm (estimated) inseam will reach the ground with both feet flat on the 1998 Bimota YB9 SRI, with a cramped knee angle of around 70 degrees and a forward-leaning riding position.

Data quality: estimated (wheelbase estimated from this category's typical bike, not this model's own spec). Assumes about 30mm of suspension sag once seated (a typical street-bike rule of thumb - stiffer or softer suspension will vary). This is an approximation from category-typical geometry and generic body proportions, not a measurement of this specific bike or you - sit on it before you buy.
