The VS Racing 2101B Competition Off-Road Buggy Engine is a super long stroke .21 off-road engine is based on the powerful O.S. Speed 21XZ-B Spec II. By combining the experience, precision and technology of world famous OS Max engines, with additional tweaks and changes from the mind of legendary Rody Roem, the 2101B delivers a balance between high performance, reliability and cost.
The biggest changes can be found in the crankshaft and the combustion chamber. The 14mm turbo crankshaft and turbo head button have been "Rody Modified". This includes balancing, porting, lightening and silicone ramping the crankshaft intake.
