Polini Team 4 Sports exhaust system for Yamaha/ Minarelli horizontal 50/70cc 2-stroke engines.

The Polini Scooter Team 4 exhausts have been developed for Yamaha scooters using technology from the Polini Italian Cup races. Expansion chamber sizes have been optimised and the number of cones increased to maximise performance and enhance the racing look. Based on data from the top-of-the-range Polini Big Evolution mufflers, this exhaust combines track-derived technology with street-legal use.

The silencer features black anodised aluminium construction with a detachable back cover for easy replacement of the deadening material. Designed for passion-driven riders, these mufflers are suitable for both city use and tuned engines.

Features:

• Street-legal homologation for specific models

• Optimised expansion chamber for improved performance

• Black anodised aluminium silencer with detachable rear cover

• Compatible with tuned and original engines

Please note: Yamaha Jog R (A/C) Euro2 (must be fitted with a Polini cylinder kit)
