Fits: BMW C GT 650 ie 4T LC euro 4 2016-> BMW C Sport 650 ie 4T LC euro 4 2016-> (652EA) The variator is very easy to fit and very easy to personalise. It is designed specially, down to the smallest detail, separately for each application. With a variator like this the scooter runs at higher revs with more zip and more willingness when you open the throttle than you would ever have had with the genuine variator. That is exactly what Malossi's engineers set out to achieve.
