41mm everyday tuning kit with 55 cc displacement and reed valve intake, suitable for Swiss mopeds / mopeds with Sachs 50/2 (502) engine.
Ideal for beginners and anyone who prefers an unobtrusive and quiet performance increase.
With a larger displacement and optimized timing, this tuning kit turns your oldie into a powerhouse. In addition, this racing cylinder is visually indistinguishable from the original cylinder when fitted.
In addition to the cylinder, the kit also includes an exhaust with 28 mm flame tube and a 13 mm racing carburetor. The square intake flange with 13 x 13 mm opening corresponds to an area of a round 15 mm tuning carburetor and gives your bike plenty of steam under the saddle.
The set includes the following fixed parts:
