Malossi Sport 70 strong torque cast iron cylinder kit with robust piston and 2 rings. Easy to tune and original carb is retained. Supplied with all necessary mounting parts, instructions, gaskets etc. Our Tip: Water-cooled versions have something in reserve, so experienced tuners can tickle more power from the cylinder. Original carb may be retained, but a larger carb will mean increased performance. Sports exhausts such as Leovince ZX, Turbokit R, Tecnigas Next R or Metrakit Handmade are a great choice too.
