cylinder kit Naraku 63cc 42mm for SYM 50cc 4-stroke, Peugeot 50cc 4-stroke NK101.65

For those who do not want to go radical with performance tuning such as 47mm or 51mm, but fancy a little more grunt, there is a 63cc cylinder kit with noticeably better drive than the 50cc original. This cylinder kit will iron out holes in the drive as well as on inclines. Kit includes cylinder, piston, piston ring set, oil scraper rings, gudgeon pin, gaskets and circlips. The piston has 2 CNC-machined oil grooves to stabilise the oil coverage. Lubrication of the gudgeon pin is taken straight out of motorsport and is aided by additional oil holes and grooves. Also suitable for other scooters with new SYM 4-stroke engines (bore/stroke: 37x46mm) e.g.:

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-stroke
