Slider Yamaha T-max 500/530 Polini

Slider Polini to allow the rotation of the spring and for it to work much better.
Especially designed for T-Max pulleys. With a slider, the response of the transmission will be more direct and progressive and the behaviour of your bike will improve in many aspects.
Includes a rubber, a high-resistance plastic guide, and a fitting for the spring.
Combines perfectly with Polini springs but can be used with the original or others.
