VS RACING VSB05

The new and exclusive VS Racing VSB05 long stroke .21 off-road engine is based on the very powerful O.S. Speed 21XZ-B specII and is an extraction of the world famous OS Max precision and technology together with some additional ‘Rody’ touch and development, equipped with a VS Spec combustion chamber with o-ring to protect this area from dirt, a 5-port sleeve and additional DLC coating on the whole crankshaft, a rear-cover with “pushplate”. 

The difference between the VSB04 is a new carburetor type OS22E which gives a better response and better fuel-milage.

The VS Racing VSB05 is suited for high competition 1/8scale off-road racing.
