The Attainable Superbike

With ride, traction and acceleration approaching that of its award-winning carbon brethren, and a price that's far more approachable, the F-Si Alloy is World Cup DNA for the rest of us. 

Smartformed Alloy Frame

Each tube in the F-Si Alloy frame has been tweaked and refined to reduce weight, increase strength and maximize ride quality.

Short Chainstays

A curved seat tube and SmartFormed alloy shaping permits shorter chainstays for race-winning traction and exceptional lateral stiffness.

Fit-Focused Wheel Diameters

The best possible fit for riders of all sizes, with 27.5 wheels used on size small, with 29" wheels on medium through x-large sizes.

System Geometry

A progressively-slack 69.5 degree head angle gives stability, while longer rake forks reduce trail to deliver snappy, responsive handling.

Save Stays

Optimized seat stay and chain stay shaping delivers a smoother ride without sacrifice to lateral stiffness.
