The BUB Seven is powered by a custom V-4 engine. This engine is purpose built for motorcycle land speed racing. From a blank sheet of paper this engine was designed for one thing, power the world’s fastest motorcycle. The maximum limit for this land speed racing is 3000cc. The engine also needs to fit in a space 18 inch x 28 inched so part of the initial design is to fit this compact space. The V-4 concept was used for two reasons, one to fit into the packaging and two the unique surface of the salt flats requires a engine with traction control. The engine is a big bang type so that the engine can gain traction then relax and transfer power with the next power pulse. Unlike drag racing one of the challenges in LS racing is that the motorcycle has to make two runs; a down and return that make the average for the record,so the engine has to survive for both runs without any modifications.
