Our cheapest clutch bell (from Asian production). Suitable for many 50cc Piaggio, Peugeot, Kymco, SYM and 4-stroke scooters with 139QMB engine (so-called DIY scooters). The clutch bell corresponds in structure and dimensions to the original part. The inner diameter is 107mm. For tuned scooter engines, we recommend higher quality clutch bells eg Malossi, Polini or Naraku, as these are balanced and have a better heat dissipation due to different structure. AI-translation
