Yamaha TRX850 Enthusiasts Forum

Hi, does anyone know if the TRX rear sprocket is the same fitment as the YZF 750.

Cheers

Is it dished? as standard TRX was.

The rear sprocket carrier for the TRX and YZF is exactly the same so yes the sprockets are interchangeable BUT the standard YZF item has a few more teeth than the standard TRX one.

Early TDM sprockets will also fit.

If you want advice on bigger or smaller sprockets for the TRX, speak to B & C express.

Also search the forum...

When is was looking for sprockets i found this website www.jtsprockets.com it has a good catalogue with drawings so you can mix and match different models , I was looking for a 525 rear sprocket to fit a r1 rear wheel on my trx. I have also used bandc and talon in the past. Talon will make you an alloy rear one to order if they haven't got it in stock (very helpful) .

Cheers for the info, I can now put my gearing back to standard.

Mate, dunno what you're up to, but if you are fitting your TRX sprocket on a newly-fitted YZF rear wheel maybe, dont forget the YZF runs a 180 tyre which had a bigger diameter.

Hi trixynut, i am just trying to get the gearing as close to standard as possible. The bike is currently running a 42 rear 17 front with a 180/55 tyre. if i run a 39 tooth rear sprocket i won't be far away according to gear commander.

The gear commander is a good little site, I have been playing with my gearing lately, ive got a 16 /17 teeth front and 41/43 rear . currently running 16/43 i think its about 125 ish in top.
