Hey all, First post. Can anyone give me any advise/direction re; setting up an RM-Z 450 for Motard racing? I'm doing some research for my Bro who has just taken up the sport having raced Pro 250 Moto-X for a number of years. I myself am strictly Road these days. Where would I look for RM-Z compatible hubs to lace up a new set of Motard wheels and what is the best rim spec.? I've been looking around online and it looks like 17 X 3.75" front and 17 X 4.5" rear is the go but the Motards I have seen look to have a wider rear at least. Also, is going to a 320mm front rotor and adding an adaptor for the stock single piston floating front caliper sufficient or is it really advisable to get a 6 pot dual retracting pad anchor for the front? What else is recommended when converting a stock MX bike? Cheers, Arran.
