    OE Sprocket ??

    I was doing a bit of polishing at the weekend, felt a bit like I was just getting it clean to get it dirty again  :087: but there wasn't much else to do..

    Anyway, I noticed the sprocket nuts look a bit chewed up (ordered new  :001: ) and wondered why on such a low mileage bike they would have been touched..  :084: so, possibly to change the sprocket, but  why  :027:

    Anyway, please see attached photo, is this an OE sprocket?

    It's a Gen-1 and that's not the OEM sprocket. Do you know how many teeth it has..?? The axle looks further forward than normal so it may be 46 or 47 teeth if the chain hasn't been shortened.

    Cheers Smithy. I didn't check the number of teeth but I have a few photos so I'll take a look and see if it shows up, if not I'll take a look when I get home tonight.  :028:

    I guess I should check the front while I'm at it. Dealer never mentioned that the sprocket/s had been changed, let alone if they went up/down with the number of teeth.

    Looks like a Renthal sprocket to me, I can just make out "4732" just above the swingarm but I couldn't find anything, but from what I've seen, Renthal only offers 520 pitch sprockets for the XR so yours may have had a 520 conversion, though they also only go up to 46T which wouldn't make a massive difference to where the wheel was sitting, who knows, what's more likely is it's a 42T and the chain had 2 links taken out cos that sprocket does look relatively small.

    42T Aluminium sprocket on mine..! Had a bad chain with a couple of sticking links...So I put the 42T and DID ZVMX on after only 5k km in 2017 due to the bad chain and has been there ever since. Now have just shy of 52k km on it and still in good nick.

    Renthal do 525 for the XR in std 45 tooth

    OP it's certainly a Renthal, chain looks new too so guessing it's just had the set replaced. What miles does the bike have? If not looked after the chain could be goosed by 10k. Or the last owner might have just wanted better looking /lighter rear sprocket

    7k miles on the clock.. if the original owner wanted it to look better he certainly should have been more careful with the spanner, or molegrips  :008:

    Not near the bike tonight, I'll take a closer look tomorrow  :084:

    My guess is the previous owner has stuck a smaller rear on to drop the revs at cruising speeds and had to change the chain at the same time. It is a revy bike after all which is a bit of a shock if coming from a GS.

    Personally I like revs, they're lovely.

    You're a perv H, I bet you haven't even attempted to rid the bike of vibrations..  :156: :008:
