Malossi aluminum cylinder with 3-ring sport piston
Nikasil-coated aluminum cylinder for better heat dissipation.
The sport piston with a very compact 3-ring design ensures perfect sealing against the cylinder bore. The piston itself has a very high silicone content, which results in a very low expansion coefficient under load. The piston has been reinforced at the critical points and is even lighter than the standard pedant.
