POLINI Ø43 CYLINDER KIT FOR VESPINO F9 AND GILERA GSA AND ALX

Polini introduces the new Ø43 mm, 65cc cylinder kit developed for Gilera GSA, ALX and Vespino F9.

The cast-iron cylinder has been updated in its port timing, transfer ports and exhaust port design, with the aim of improving overall engine performance. The result is quicker throttle response, increased power and improved over-rev capability. Compared to the previous version, the new cylinder kit delivers an additional 1 HP and increases the engine speed range by 1000 rpm.

The kit is supplied complete with a cylinder head specifically designed to work in perfect harmony with the Polini cylinder kit. The cylinder head will also be available separately and is fully interchangeable with the original component, providing dealers with a double commercial opportunity: completing the Polini kit installation or offering it as a technical replacement part for standard engines.
