Made by the racing legend Kübler Tuning, who have made almost everything that has anything to do with scooter technology faster and stronger.
The completely redesigned combustion chamber, with a greatly increased compression, produces a noticeably impressive increase in power over the entire speed range.
The dome is milled from the solid, the spark plug position is unchanged from the original head, so the original outer water cap can still be used.
Right easy to implement tuning which offers an impressive increase in performance within only 1h working time!
