Easy to tune variator from Top Racing. The variator can be used with original belt. Supplied with unrestricted vario sleeve and 3 sets high quality weights (16x13mm) 8.5g - 7.5g - 6.5g and you should never need any more weights than are offered here. This variator provides increased acceleration and top speed. Our conclusion: This part is as good as famous brands such as Malossi Multivar. The build quality is generally very good. Lots of kit for a good price.
