Stage6 Streetrace 77cc Engine Cylinder Kit and Crankshaft Derbi Euro 3/4

The Stage6 Streetrace 77cc cylinder kit and crankshaft is the ideal choice for those looking to enhance the performance of their Derbi Euro 3/4 scooter. This package includes a 77cc gray cast iron cylinder, featuring a bore of 50 mm and five exhaust ports, ensuring excellent exhaust efficiency. The cylinder head, made from a single piece of high-compression aluminum, guarantees optimal combustion, while the piston with two rings at 50 mm contributes to a quick and dynamic response.

The HPC crankshaft, with original stroke and a 12 mm piston pin, is designed to offer greater strength and reliability, supported by SKF C3 steel bearings and seals, which increase its longevity. This kit not only improves top speed but also enhances the overall performance profile, making it perfect for intensive use.

Ease of installation is an additional advantage, as no machining of the housing is required. It is advisable to follow a break-in period of 300 km, avoiding full load, and to use a 3% two-stroke mixture (1:33) to ensure engine longevity.

With its understated and discreet design, the Stage6 cylinder has been conceived to perfectly integrate with the original aesthetics of the scooter while delivering high performance. This kit represents a significant step forward for those looking to push their vehicle's potential to the max without compromising reliability.
