The 50mm 80cc METRAKIT PRO RACE version.
Not approved, prohibited on public roads, reserved for competition and closed, private circuits.
A small powerhouse, a direct competitor to the MALOSSI MHR TEAM 80cc, but significantly more advanced, this is one of the best 80cc cylinders for stock 40mm stroke crankshafts on DERBI EURO 2 engines. The 50mm bore cylinder features 5 intake ports and a well-designed exhaust port with boosters. The exhaust port and transfer ports have been meticulously crafted. The cylinder head is a two-piece design. The cylinder head cover is gold-colored, reminiscent of the heyday of METRAKIT in the 2000s and 2010s! It uses a 50mm graphite-coated ATHENA piston.
As an option, we offer a Stage 1 preparation. This preparation involves modifying the exhaust port by increasing the port timing and improving the flow, thus increasing cylinder performance. Skirt modifications are also included in this service. Please allow a little extra time for this preparation.
This top end is compatible with 50cc motorcycles with gearboxes equipped with the DERBI Euro1 and Euro2 engine:
