TUNING SPORT – high-performance Product description
In contrast to conventional variators:This design of variator uses gliding weights, instead of rolling types, which facilitate the variomatic to open linearly, which has proved to be a very simple but effective technological development! Its linear design is the secret of the ‘turbo effect’ provided by these pulleys. Compared to original items the J.Costa units offer a shorter transmission ratio at lower revs, which leads to a quicker acceleration. Simultaneously, when the weights have reached the end of their travel (pulley fully opened), they also possess a taller ratio at higher revs, providing an increase in top speed.
Conclusion:
The unique Variomatic technology employed in the function of the EVO range has been once again improved and proves it with even more performance throughout the rev range! Do not forget a new ‘V’ belt. A performance orientated clutch and clutch bell completes the set up!
