The latest spec 475 kit used in conjunction with JL pipes & standard bored carbs is now giving up to 80bhp at the wheel! With bored carbs (28mm / +2mm) and Zeeltronic or Ignitech programmable ignition 80bhp plus is achievable.

The 2018 CRMC Post Classic 750 championship was won this year by Joe Barton on a 444cc big bore kitted NS400R tuned by ourselves with a reliable 76bhp at the wheel, taking many circuit lap records on the way.
