The Bimota Tesi 1D is a testament to motorcycle innovation’s pinnacle. Displayed at the esteemed Naked Racer Moto Co museum, this motorcycle is the first of the exclusive 20 units produced. Notably, it has only 800 miles on the odometer, highlighting its pristine condition and the meticulous care it has received over the years. An exclusive signature from Pierluigi Marconi further emphasizes its rarity.

Revolutionary Design and Performance

The Tesi 1D’s innovative hub-centre steering system is central to its design, a significant departure from traditional motorcycle steering mechanisms. This system effectively eliminates the front-end dive during braking, providing a stable and controlled ride. Powered by a 904cc Ducati Superbike engine, the motorcycle delivers 120 horsepower through its four-valve setup, blending high performance with a unique aesthetic.

Advanced Components and Assembly

The Tesi 1D’s assembly includes finely milled alloy plates that hold the engine forward in the frame to avoid contact with the front tyre, enhancing stability and weight distribution. Suspension duties are managed by Marzocchi gas shocks, with a horizontally mounted shock for the front and a vertical shock in the rear, linked directly to the swingarm. This setup contributes to the Tesi’s distinctive handling characteristics, which limit the front end’s dive under braking and provide a stiffer, more controlled ride.

Aesthetic and Functional Innovations

Visually, the Tesi 1D is as striking as it is functionally innovative. The motorcycle features a futuristic LCD dashboard with digital instrumentation—a state-of-the-art feature in 1991. This includes a speedometer, tachometer, and various temperature and fuel readouts, enhancing functionality and rider interaction. The exhaust system also diverges from convention, with twin pipes that split from each cylinder head to individual mufflers, reducing back pressure and improving performance. The bodywork comprises a three-piece structure that cloaks the radical substructure, including a GP-style’ hugger’ on the rear tyre and a colour-matched front mudguard.

Historical Context of Hub-Centre Steering

Though innovative, the concept of hub-centre steering is familiar in motorcycle design. Its origins trace back to early models such as the 1911 Militaire and the Ner-a-car of the 1920s, which experimented with steering mechanisms that diverged from traditional forks. Bimota, a niche Italian manufacturer based in Rimini, chose to refine this idea with a modern interpretation, resulting in the creation of the Tesi 1D. Unlike previous iterations by other designers who viewed such systems as rudimentary, Bimota embraced this complex steering design, aiming for precision and series production readiness.

Legacy and Resurgence

The original production of the Tesi 1D ended when Bimota faced bankruptcy in 2000, a casualty of broader financial difficulties within the company. However, the resurgence of the brand in 2003 brought with it the Tesi 2D and later the 3D, each iteration building on the original’s foundation with significant enhancements. These models continued to push the envelope in motorcycle design, proving that the legacy of the Tesi 1D as a harbinger of future innovations was well-founded.
