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.

Features:
  • Performance that rivals that of the acclaimed Speed 21XZ-B Spec II
  • Shares the same piston, liner and con rod as the (now discontinued) Speed version
  • Lightening holes in the cylinder head reduce overall weight
  • Other enhancements include a lower CG and improved cooling
  • A 22B2 single needle carb makes tuning a breeze
  • Optimized power band
  • Silicone filled crankshaft with tungsten counter weights
  • Blue anodized head
  • Incredible throttle response
  • 7mm carb reducer is included

  • Displacement: 3.49 cc
  • Bore: 16.27 mm
  • Stroke: 16.8 mm
  • Practical RPM range: 3.000-41.500
