Cylinder Kit AC Top Performance Black Trophy 70cc 10mm Minarelli Vertical

This is the next generation of the Top Performance Trophy. The cylinder has been reworked to maintain its legendary reliability and durability. Performance is very similar, but can be achieved at a slightly lower rpm, thus improving efficiency. The kit remains in the sports category, but when combined with the right exhaust, performance is excellent for an entry-level cast iron engine.
