Cylinder Metrakit ProRace 3 70cc Derbi Euro 3 / 4

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.
As a novelty, Metrakit Cylinders are now also offered with Vertex pistons (d.47.6mm).
A true Cylinder gem that should be combined with competition components.

It is a Cylinder designed for racing,

The Pro Race Cylinder is made of a special aluminum 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 composed of two pieces, head and small head. The same special alloy of the Cylinder is found in the small head, which provides maximum safety for the performance required in competition. The design of the small head is engineered to increase cooling capacity and withstand the high temperatures and high revolutions it reaches.
The material of the O-rings is Viton. It is the most suitable material for this function, proving to be the one that best maintains its hardness, elasticity, and sealing properties at high temperatures.

The piston, 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 retains all its properties during long competitions.
All of this has been studied and tested for the toughest competition at the highest level.
