• Polini Performance Big Bore Kit (165cc); Stella 4T Manual

Take your Stella 4T Manual to the next level by strapping on this 165cc big bore kit.  This kit will make the bike go significantly faster and have extensive more power through the middle gears.  It's a must have for any 4T that is pulling a sidecar or riding hillly terrain.  You will need to replace your stock air box upgrade your carburetor.  We recommend our Scooterworks Racing Air Filter, and the Polini 22mm Carburetor.

The Polini Exhaust also goes well well with this kit. 


*NOTE*  This cylinder kit will not work on 2-stroke and Automatic Stellas.

Not legal for use in California on pollution controlled vehicles. Check local laws before installing.
