2005-2009 Honda CRF250X Close Ratio 6 Speed Gearbox 

<< back to products

The immanent demise of the 2 stroke engines in the smaller classes has identified the need for engines such as the Honda CRF250 which could provide an ideal replacement, especially in the up-and-coming Moto 3 class.  With this in mind Nova have designed a 6 speed road racing gearbox.  Comparison of the percentage drop figures clearly illustrates the need for a purpose designed transmission to obtain the optimum performance from this type of engine when put to use in an entirely different application.

 

This kit includes two assembled shafts, a new selector drum and three selector forks.

 

Available With Superfinish
