RONDA DRAKE, wife of the world's top professional 1/8 OFF ROAD racing driver ADAM DRAKE, who competes in the ROAR National Championships, the premier OFF ROAD event in the USA, is also a TOP driver. He participates in the main races with his Model MUGEN and ADAM by his side. We are pleased to announce the release of the OS SPEED B21 RONDA DRAKE EDITION 2 with an impressive and redesigned cooling head (this time dominated by black with pink accessories) and aluminum interchangeable diffusers, in what else but pink color.

The OS SPEED B21 RONDA DRAKE EDITION 2 engine impresses with its high torque in the medium to high speed range with linear power development and low consumption. The DLC-coated crankshaft has two tungsten weights for perfect balance and maximum smoothness. OS SPEED B21 RONDA DRAKE EDITION 2 has a lower and mainly lighter cooling head for the best possible cooling at high ambient temperatures and maintaining a low center of gravity. The O-ring between the cooling head and the combustion chamber insert reduces vibration and protects against contamination in the best possible way. The 22E carburetor guarantees perfect response and maximum power development.
