O.S. Engine MAX-21XZ-B v2 Off-Road Race Engine
We are pleased to introduce the MAX-21XZ-B Ver. II for drivers who demand performance close to that of our flagship model, the O.S. SPEED 21XZ-B spec. II but at a more affordable price. Many top drivers around the world choose O.S., relying on the renowned linear acceleration to get the best power at the right time. We developed the MAX-21XZ-B Ver. II based on the O.S. SPEED 21XZ-B Spec. II but adopted a single-needle carburetor for easier adjustment. We use the same piston/liner and connecting rod from the flagship model, the O.S. SPEED version, in the new MAX-21XZ-B Ver. II. The crankshaft has the Tungsten counter weights similar to the O.S. SPEED, but without the ultimate DLC coating, offering superb value for money.
