For all those who do not want to mount a performance tuning a`la 47mm or 51mm and yet do not want to do without that certain extra power, there is a 63cc cylinder kit with noticeably better pull compared to the 50cc original cylinder. This cylinder kit can help with starting difficulties and problems on the mountain. Included in delivery are: Cylinder, piston, set of piston rings including oil scraper rings, piston pin, gasket set and circlips for the piston pin. The original cylinder head can still be used here. The piston has two CNC-turned oil grooves in the piston skirt to stabilize the oil film. From racing, the lubrication of the piston pin was taken over by additional oil holes and grooves.

Also suitable for other scooters with new SYM 4-stroke engine (bore / stroke: 37mm x 46mm) eg:

SYM Mio 50
SYM Fiddle II 50
SYM Orbit II 50
SYM Jet4
SYM Allo 50
SYM Cello 50
SYM Symphony 50
Peugeot Vivacity 4-stroke
Peugeot Speedfight 3 4-strokeAI-translation
