For racing and tuning fans: Metrakit Cylinder Kit 77cc Pro Race 4 d.50mm Derbi Euro2, the 4th incarnation of Metrakit's "Pro Race" cylinder. Metrakit improved their Pro Race kit again, this time they achieved their goal by increasing bore / piston from 47.6mm to 50mm and displacement from 70cc to a whopping 77cc. Here are the details:
- aluminium cylinder with 5 transfer ports and boost port supported exhaust
- cast piston Athena 50mm with 12mm pin, 1 chrome ring 0,8mm
- modular cylinder head, gold
- cylinder gaskets (head and base)
- 4 stud bolts, long
- water connection
The 77cc Pro Race 4 is easily one of the most powerful racing cylinders. More power, improved torque, better acceleration, and it is definitely the higher rpms where this kit will show its full potential.
We recommend adding a top-of-the-line reinforced crankshaft with standard connecting rod and standard stroke, a 28mm carburetor, a reinforced clutch and a racing spark plug index 10.
