The history of the record
The BMST are known for their extraordinary top speeds. The current FIM-recognized world record for motorcycles dates back to 2010 and was set by Rocky Robinson on a Suzuki Hayabusa. At that time, Robinson reached a speed of 376.156 mph (605.697 km/h).
Denis Manning, the designer and developer of the BUB Seven Streamliner, has already broken the record for the world’s fastest motorcycle twice with his machine. In 2006 and 2009, the streamliner took the lead, most recently with a speed of 367.382 mph (591.244 km/h). This record stood for 366 days before being broken again by Robinson.
Technology: turbo power and aerodynamic efficiency
The central element of the new record attempt is the engine: a 2,997 cm³ V4 engine with turbocharging, which was developed specifically for the streamliner. Specific performance figures have not been disclosed, but it can be assumed that the engine delivers several hundred horsepower (kW) and Newton meters of torque to overcome the enormous air resistance at speeds of over 600 km/h. The exact performance has not yet been officially confirmed.
The challenge in such records lies not only in sheer engine power, but also in the optimal interplay of aerodynamics, traction, and driver skill. Rivas emphasizes: “Everyone is looking for four hundred miles per hour. It’s about creating something that no one has done before.”
The approach to driving differs significantly from other disciplines. While in drag racing the throttle remains almost permanently open, on the Bonneville Salt Flats the power must be handled sensitively in order to maintain traction.
