POLINI Roller Set 25 x 14.8 mm – 13 g (8 pieces) - Manufacturer Ref. 242.225
Optimized for the primary transmission of scooters, these POLINI rollers form a complete set of 8 pieces designed for the variator. Designed for urban use and daily riding, they allow for fine-tuning the engine behavior by modifying the variator settings: acceleration, rev range, and usage range can be adapted by changing the weight of the rollers.
Easy to install during variator maintenance, these rollers are suitable for technicians and DIY enthusiasts looking to optimize the scooter's response without replacing the entire transmission. Notable compatibility: YAMAHA T‑MAX 530 (models SJ09, versions 2015–2016, including ABS and Iron Max). Follow manufacturer recommendations for installation and balancing to ensure longevity and performance of the transmission.
