43 mm tuning cast cylinder with 63 cc and 12 mm KoBo suitable for your Piaggio Si, Bravo 2 and 3 as well as Grillo moped / moped.
All necessary parts are included in the scope of delivery, including the matching cylinder head for installation.
Notes: We recommend using this tuning cylinder in conjunction with a larger exhaust and a larger carburetor. This racing cylinder may still have residue from the manufacturing process. The cylinder should therefore be cleaned with compressed air or brake cleaner before installation. This should be between 0.15 - 0.4 mm to prevent the piston from jamming.
The set includes the following fixed parts:
