drive belt Polini Aramid Belt for Aprilia, Gilera, Piaggio long version P.13685 fitting for Aprilia SR Racing 50 MZC 1997-1999,

The most durable v-belt Polini offers has additional aramid fibre inlays that make this belt extremely resistant to tearing. This is not Polini’s top choice for the race track for nothing. The grip is so good that, despite the high Kevlar content, the belt slip is heavily reduced when cold. This product is at home on any race track, but can be used in a standard engine where better performance is demanded.

Dimensions: 805-18.5-30. OEM number for reference: 436864
