Nova Racing 2009-2017 Aprilia RSV4 Close Ratio 'B' Gearset

$ 2,086.06

A set of close ratio gears for the Aprilia RSV4.  We supply the loose gears 1st to 6th output and 2nd to 6th input.  These should be built by the customer onto the standard input and output shafts using genuine Aprilia circlips, washers, bearings, etc.

All engagement dogs are undercut to promote positive and rapid engagement, and backlash angles have been optimized for each gear.

All gears are superfinished as standard
