Nova supply all 10 loose gears for both shafts (2nd to 6th input and 1st to 6th output), and two selector forks.  Assemble using standard Yamaha input & output shafts and selector drum.

Benefits

  • Faster gear changes both up and down the gearbox in 1st-4th gears.
  • Engagement dogs with varying undercut on drive and overrun sides to give lighter downshifts.
  • Ratios optimised for track use to make the most of engine characteristics, maximising speed and performance on the track.
  • Engagement dog angle optimised for racing to give positive shifts, les backlash and stronger dogs.
  • No shimming of gears required and increased fork life.
  • Billet material increases fatigue strength.
  • Comparable cost to kit racing parts.
  • Can be used as an upgrade from an existing full Nova CR box for reduced cost.
