TJT Variator for Derbi and Honda mopeds. Pair this with the DOS ramp plate for a boost in all around performance. Don't forget to add the guides if you don't have a set already. Better acceleration and top speed with a bolt on part is pretty hard to beat. Comes with tuning weights and a new contra spring.
Uses 16 x 13 roller weights. Reuse your variator slide from your stock variator.
These have the good bushing.
