The OS Speed B2105 RC engine has evolved into the fifth generation of the B21 series. It is designed to secure power that gives an advantage in harsh off-road racing scenes and pursues a driving feel that steadily demonstrates performance in any situation. By re-designing the cylinder liner and crankshaft, we have achieved smooth and linear power delivery. Furthermore, the effect of a lighter outer head successfully improves drivability in any situation.
