Motoforce Racing variator kit for Yamaha Aerox/ Minarelli engined scooters.
This is a great upgrade over the standard Aerox variator, the performance and shifting have been significantly improved on this variator and this kit offers superb performance value for money.

NOTE: This variator will also fit Chinese 2-stroke Minarelli style engines which use a 13mm crank, but check carefully before ordering as most Chinese 2-strokes use 16mm crank end.
Due to the differences in Chinese scooter manufacturers check this guide carefully when fitting.

Includes 15mmx12mm roller sets in 5.5g and 6.0g.
