There seems to be more and more members appearing that are racing the ZXR400 so i've created a special section just for you to show off results, discuss meets etc etc.
Haven't come across any myself. I've had a mate just stick a thick layer of weld over the danger area on the existing one so it can withstand a couple of crashes before it wears through.
What you do is cut the whole end of your crank off so it stops at the cases, with a plug in the end. then flat plate of Ali and you'll never need crash protection again
