Morning all.
As said by Biggles OEM stuff is probably the best, but it aint the cheapest.
Ditto Sideshow & Toonyank r/e B&C & Tsubaki that's the place to get them from (unless you come to me of course, forum dicount nudge nudge
).
I've used Tsubaki for quite a while now, & I reckon you can't beat it, go for SG or SGX grade chain, & JT sprockets. If you want Renthal sprockets make sure you get the hard anodised rear, it really is worth the extra couple of quid.
Lastly, EBC are the pads to have. HH pads in the front, & std rears
Cheers.
