I just typed a lengthy response and when I pressed "post", my internet had a hiccup
Lost everything!!!
So, in short:
My wheels were custom made for an S/E, so no clear answer from me.
Anyways, im sure the stock SM's will be close to bolt-on.
And if not, can be sorted with custom spacers, etc...
Rear brake disc NOT interchangeable, SM is 240mm (from RMZ), E is 220mm dia.
Front, you can use the E disc, just wont have the awesome stopping power of larger disc.
Larger front disc requires relocator bracket that slots in between your caliper and fork-caliper mount. (Like a spacer). Moves the whole caliper backwards/outwards towards the motor. Makes a MASSIVE difference in stopping power.
The relocator/spacer is made by Motomaster or Braking, check online.... I think also Talon... Not sure...
Next issue... Most aftermarket front discs are 320mm dia. Stock SM front disc is only 310mm, so if getting a bracket for stock wheel, make sure it is for 310mm and NOT 320mm. Not sure if they do make it for 310mm even... Once again, Braking or Motomaster.
Also, you need smaller rear sprocket for SM wheels, with normal E/offroad gearing you riding a pogo stick, gearing too low/short. Its fun for an hour or so, but it gets tiring...
Also adviseable to use 2 different chains for the 2 setups.
Anything else, just pm me, or get my number from Captain J, and gimme a ring. (Before Sat night, will be out of SA for a month)
And just to wet your appetite a little...
