I'm looking at buying a chain and set of sprockets for my ZXR at the moment and I'm considering this Renthal kit (http://www.mandp.co.uk/productinfo.aspx ... rl=Renthal) which has an aluminium rear sprocket. From what I can tell aluminium is better because it's lighter but then it wears faster because steel is stronger. Does anyone have any thoughts of which brand chain/sprockets are best? And the best material for the rear sprocket? Any help would be greatly appreciated

Jack.
