900 sprockets & chain on a 600...?

[Johnnyrob]

I've sourced an all but new 520 Gold DID chain & sprockets from a M900.

However, I've discovered the front 15t sprocket is incompatible fitment on the M600 (Doo'ooh) and the rear is a Renthal 38T item.

Will the chain and rear 38t work on the M600 with the correct 15 or 14t M600 front or will the gearing be wrong due to the 38t on the M600?

What is the difference in the front sprockets?

I thought you just turned them the other way around because of the offset of the rear wheel!

Waiting to be enlightened.

Cheers Yorkie - I thought I read on here that the 900 was a differing fitment? If I can turn it around to align it then that's great. Certainly looks like B&C express supply the same part to both bikes 8)

Any ideas about the rear sprocket? 38t instead of 46t? Will this totally bog the bike down due to a lack of low range?

46T down to 38T is a big drop & I think the 600 motor will be overgeared. The stock 15/38T gearing is too tall for a 900 TBH, and that engine's got an extra 25 horses. Would recommend sticking to near standard if possible
