Athena 47.6mm Big Bore Cylinder Kit for Minarelli and Yamaha Zuma
This Athena 47.6mm vertical cylinder kit is an upgrade intended for Minarelli and Yamaha Zuma scooters. It raises engine displacement to 70cc, which can deliver more power and efficiency. It is one of the Minarelli 50cc / Yamaha jog scooter parts available for boosting how your ride performs. Riders who want to get the most out of their scooter will find it useful, and everything needed for installation comes in the box.
Build Quality and Included Parts
The cylinder is made from strong aluminum and has a nickel carbide plated bore that resists wear better. The kit includes the cylinder, cylinder head, piston, piston ring, piston pin, circlips, and gaskets. It also ships with carbon fiber reeds, which help airflow and performance.
Fitting Notes
The Athena kit is built for a fairly simple installation, but the engine cases may need to be modified to clear the larger cylinder. It suits "Pre-Bug Eye" Zuma models made from 1989 to 1990 and from 1997 to 2001. Before starting the upgrade, riders should check their current setup.
