Fits all model 250cc up to 1977. Most models will need the piston modified for your application. These pistons fit 1973-1975 Pursangs and 1975-1976 Frontera and 1975 Astro without modifications. Standard bore on most models is 72mm but on 1976-1977 Alpina & Sherpa T the standard bore is 71mm so using the 72mm would be 4th over. 


  • Please include your cylinder # or model # to help get your order out quicker as some models need modifications to the piston.
