Not approved for use on public roads, reserved solely for competition such as the MHR GP 80 and the super moto trophy, the races for which this top end was created.
Here is the latest top-end kit from METRAKIT. The PRO RACE 4 80cc is a 50mm bore cylinder designed to work with the stock 39mm stroke MINARELLI AM6 crankshaft. This is the most advanced version from the Spanish manufacturer and is the result of all the brand's racing experience with MINARELLI engines since the 2000s. With 5 intake ports, a booster exhaust, and a cylinder head with a stud, this engine is designed for high performance while remaining robust! Obviously, it should be used with a large carburetor (24 to 28mm), a suitable racing exhaust, a reinforced crankshaft, and ideally a digital ignition like the MVT DD! Note that the exhaust outlet has a 2-bolt flange fitting like the DERBI ! You will need to either use the special METRAKIT PRO 3 exhaust or a DERBI type 2-bolt flange ball joint!
As an option, we offer a Stage 1 preparation. This preparation involves modifying the intake and exhaust ports by increasing the port timing and improving the flow, thus increasing the cylinder's performance. An improved piston and skirt are also included in this modification. Please allow a little extra time for this preparation!
