The most robust Polini belt has an insert made of aramid fibre, which makes it extremely durable. There are a number of reasons why this belt is Polini`s first choice for the race track. Due to the excellent grip, the slip is reduced to a minimum when cold. This product is at home on the track but can also be used in the original engines under high loads. Dimensions: 28 ° 970x26.5x10.5mm
