Description
Metrakit ProRace 4cylinder for Derbi Euro 3 / 4 / 5 engine.
The manufacturer Metrakit surprises us after a long time, releasing this new cylinder improved over its previous version MK Pro Race3 and you can buy it at motoscoot.net. The cylinder is composed of 5 load transfers and a large exhaust with boosters on the sides.
The cylinder is made of aluminium, with a 2-piece cylinder head with high-cooling cylinder head and a 1-segment graphite piston from the manufacturer Athena.
The main difference to the MK ProRace 3 is the bore, the ProRace 4 has a bore of 50mm and a displacement of 80cc.
The kit includes:
- 50mm bore aluminium alloy cylinder with Nickel and Silicon Carbon coating.
- Gold plated cylinder head with high cooling cylinder head.
- Athena single segment graphited piston.
- Kit of gaskets of different thicknesses to adjust it to the correct squish.
- M7x125 studs
- Original thermostat adapter.
The squish recommended by the manufacturer is 0.95 for street use and 0.85 for track use.
