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 39mm original. Some say that there are already better performing scooters leaving the factory with this version as standard. This cylinder kit will iron out holes in the drive as well as on inclines. Subtle and user-friendly. Kit includes: cylinder, piston, piston ring set, oil scraper rings, gudgeon pin, gaskets and circlips. This 44mm cylinder kit comes with special pistons. The piston has a molybdenum friction-reducing coating on the piston skirt for the run-in period and 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.
