Bimota Tesi

It is distinctive for its front wheel being mounted via a swinging arm arrangement with hub-center steering, unlike the telescopic forks more common in modern motorcycles.

The model line resurfaced in 2002 with the Tesi 2/D, developed by an Italian tuner who marketed it under his name (Vyrus 984 C³ 4V).

The main innovation of the Bimota Tesi is its use of a swingarm and hub-center steering system instead of a conventional telescopic fork.

This design is intended to eliminate the "dive" effect of traditional forks under braking and to provide improved stability.

The wheel hub houses two tapered bearings and an axle, which is connected via a linkage system to a small steering column located against the frame on the left side of the bike.

[5] The frame itself is reduced to two side plates and two subframes—one at the front to support the fuel tank and handlebars, and one at the rear for the seat unit—resulting in significant weight savings.

[6] However, this architecture requires an extensive number of components to assemble the front suspension system, increasing manufacturing costs.

[7] This issue was mitigated in the Tesi 3/D, which features a tubular trellis swingarm, allowing for smaller-diameter tubes without compromising rigidity.

[7] The frame was upgraded to a hybrid structure made from aluminum alloy, carbon fiber, and Kevlar, supporting the engine.

While the hydraulic steering system remained, it severely affected maneuverability, making the bike almost impossible to ride at any speed.
