OS SPEED B2105 + EXHAUST PIPE TB02 + EXHAUST MANIFOLD MB01-75 COMBO OFF ROAD BUGGY ENGINE 1/8 1EK01 

O.S.SPEED's off-road racing engine has further evolved.

The B2105, which has evolved into the fifth generation of the B21 series, 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.

Novelty : 

The newly designed cylinder and liner applies 3 ports.

The port shape has been changed and the air-fuel mixture flow has been reviewed to achieve more torque from mid to high end.

The modified crankshaft has undergone O.S.SPEED's traditional DLC coating and the internal shape has been revised to improve not only power characteristics but also easier to use than B2104.

Drivability is improved by reducing the weight of the outer head.
