The Stage6 Streetrace 77cc cylinder kit and crankshaft for Minarelli AM6 represents excellence in the world of scooter tuning. Made of gray cast iron, this sports cylinder is designed to deliver superior performance and an enthusiastic riding experience. With a bore of 50 mm and a five-port design, the cylinder features a single 28 mm exhaust, ensuring optimal gas flow and an immediate throttle response.
The kit includes a piston with two rings, also 50 mm, and a high-compression aluminum cylinder head, which helps maximize the power output. The HPC crankshaft, with original stroke and 12 mm piston pin, ensures excellent stability and reliability, while the SKF C3 polymer cage bearings and seals guarantee exceptional durability even under intense use conditions.
With a displacement of 77cc, this kit not only improves top speed but also offers an overall top-tier performance profile, making every ride an exciting experience. The ease of installation is an additional advantage, as no machining of the housing is required, allowing for straightforward kit installation.
It is important to follow the break-in instructions, limiting full-load use for the first 300 km and using a 3% two-stroke mixture (1:33) to ensure optimal engine longevity. With a discreet design that closely resembles series production, the cylinder is designed to go unnoticed while delivering true champion performance. This kit is the ideal choice for those looking to take their scooter to the next level without compromise.
