Cylinder Metrakit Pro Race 3 70cc Minarelli horizontal LC 12mm pin

"From Metrakit come the new METRAKIT PRO RACE 3 cylinders!!!

The new HighEnd cylinder from Metrakit, maintaining its Metrakit line, continues with exhaust outlets with boosters. They have made some differences in the distribution; the new "Pro 3" consists of 5 transfer ports that are slightly larger than in the previous version.

The Pro Race cylinder is made from a special aluminium alloy, to achieve maximum performance and hardness, thus guaranteeing superior mechanical characteristics. The inner coating of Nickel and Silicon Carbide ensures the best performance.

The cylinder head of the Metrakit cylinder is made up of two pieces, head and insert. The same special alloy as the cylinder is found in the insert, which provides maximum safety for the performance required in competition.

The design of the insert is studied to increase the cooling capacity, and to withstand the high temperatures and high revolutions they reach.

The material of the O-rings is Viton, as it is the one that best preserves its hardness, elasticity and sealing properties at high temperatures.

The piston (d. 47.6mm), with a single ring, designed for a competition cylinder. The ring is made with a special treated graphite alloy and coated with thick, hard chrome, thus ensuring it maintains all its properties in long competitions.

All of this has been studied and tested for the toughest competition at the highest level, ideal for racing.

A true gem of a cylinder that should be combined with competition components.
