|
|
Hey have been through the local stealerships and cant find a listing for 525 sprockets.
Looks like the sprocket for the output shaft is just used on several Yamahas like YZF750 and TRX.
I currently run a heavy and power sappy 530 but 525 would be just right with a good chain.
I know the race guys go 520 which is easy to get hold of but I'm not doing that.
Although that would save quite a lot of weight for sure.
I went from 530 to 520 on my last bike a RG500 and it lost 1kg which i thought was pretty good combined with other reductions.
For the rear i run a aluminium blank machined so could buy a 525 and sort that ok.
Cheers

Hi Jason,
JT sprockets have a listing for the TRX850, and it runs the 525 chain:
http://www.jtsprockets.com/catalogue/model/2509
15,16,17 tooth are available.
Your local bike shop should be able to get them, or there should be plenty on eBay.
The YZF750 lists a 532 chain, whatever that is. A 520 conversion is also listed and this uses the Z13 spline, the same as the TRX850 so could be the sprocket to use for a 520 conversion.

The YZF-R6 also uses the same spline. There are listings for 530 and 520 conversions (from 532 as well) in the JT catalogue, but nothing for 525. |

hey thats pretty good info.
The YZF600 2006 on uses the same pattern front sprocket in 525.
I can see a slight misalignment happening but i can get a local motorcycle engineer to sort that.
Would just need to move either the rear sprocket outwards slightly from the hub with a spacer/shim or modify the factory front sprocket spacer slightly shorter.
Thanks for that.
Gives me more plans for the money pit _________________ YB8EI |
