I've been trying to source a 13 tooth sprocket for the DR650 (guess why

). I've searched and found the Honda XR one fits (520 chain though). Has anyone got the part number. My Honda shop haven't been able to help, but should have better luck with a number.

Cheers Dudes.

Which model XR? I havn't found any XR ones that fit.
XR 250's have 17,17.5,18,18.5,22mm inners depending on the year and the DR needs 21.7mm.

There are the ones you want (520 though).

Far Queue down here had an XR650 one if I remember right.

Cheers Nordie. I read it here somewhere that the shaft was the same as an XR650 (as Cooneyr said).

So now I've just got to find a JTF436.13?

Looks like an XR650 front sprocket will do it.
21.7/25/13 is a match for the splines.

But JT only do 14 and 15 teeth...

I'll add this info to the wiki...

Personally I'd much rather keep the front sprocket at 14t and above just for sprocket and slider longevity.

If you're converting to 520 then a 46t rear and 15 front is the same(ish) as a 13t on the stock rear.
14-15-16/46 and a 112 link 520 chain is the biz.

DON'T DO THIS! IT IS WRONG!

Hmmm...

The pre '96 DR600/650 sprockets are quite skinny on the countershaft mating surface.

The DR Big sprockets are 10mm at the countershaft and the XR650 ones are 13mm.

Stock DR are 10mm.

Those extra XR millimeters would give a bit of peace of mind when using circlips to hold the sprocket on.

Just a quick thanks to Jatz and to Nordie for volunteering Jatz.

Needed a bit of advice from the Nelson Bays boys and they came up trumps. Hopefully that favour can be returned sometime, or at least a glass or 2.

Cheers

Thanks! Probably 98% of them are pure drivel.

So far my favourite in the South Island was in Amberly.
I did have one in Nelson recently that would have given it a run for it's money though but I can't remember where it was

Was a few years ago, but the pub down by the wharf was pretty good then there was a place on the left heading to Nelson. Mussel Bouys?? But it was a long time ago. Will have to head there over the summer and have another go.

Was it that pub on the left heading north, almost out of Amberley? Had a real good meal there a few years ago on my last southern trip.

Cheers

The plan is to only use the 13 for short bursts, and switch back to the 14 (or 15). By short bursts, I mean a couple of hundred metres of extreme steepness just south of Martinborough.

Have you got the code for the XR jobby?
