Athena High Performance Variator
This variator uses larger roller weights (16x13) which improve the 50cc performance
(rollers included are: 16 x 13 7.0G)
The top speed of the 50F should be increased by 4-7mph
Good idea to order extra set of rollers a different weight so you can see what suits you best.(We suggest 5G or 5.5G rollers)
To get the most performance out of your new variator, check your belt....probably need a new one.
