Top drivers including Mark Pavidis and Atsushi Hara can vouch for the victory-taking technology of O.S.® Speed engines. Both have stood in the IFMAR Off-Road World Championship winner’s circle as a result of its powerful edge. Now another O.S. engine offers you the same advantage! The O.S. Speed 21XZ-B engine has a completely new design that delivers instant throttle response and impressive torque over the entire rpm range — all at a very attractive price. Check it out:

  • Fuel efficiency improved by 8% (compared to the 21XZ-B).
  • Black-anodized cylinder head with reduced height (by 9mm, compared to O.S. Speed 21VZ-B V-Spec.II) plus additional holes for improved cooling and less weight.
  • Lowered center of gravity for steadier car handling.
  • Newly designed 21J2(B) three needle carburetor with 6, 6.5 and 7 mm aluminum restrictors.
  • Optimized 3-port sleeve with special Speed version inner head and porting, for smoother, sharper acceleration.

  • Ceramic crankcase ball bearing.
  • P3 glow plug.
