Racing variator with noticeably better traction and more top end speed from Top Racing. The Portuguese tuning specialist uses a special rough alloy surface to for less slippage. Even the brass liner of the variator sleeve has self-lubricating properties. Very good variator, which is better than the competition from Italy. Set includes: vario weights, 20x17 at 13.5g included. Our experience has shown 9.5 g weights are ideal in 125cc - 150cc engines. The included 13.5 g are optimal for 200cc. Also fits 150cc and 200cc Kymco / Malaguti LC engines.
