Tiger 800 Roadie front chain sprocket replacement help appreciated

[Bikertone7]

Just bought a replacement chain and sprocket kit and discovered when I removed the front sprocket the new part was much thinner and also appears to be a very tight fit over the splines (I've not forced it on yet). The original sprocket is just over 7mm thick whilst the new one is 6mm and when offered up to the chain there is loads of side movement on the chain links. Before I go back to the supplier would appreciate comments if anyone else experienced the same issue. I certainly don't feel comfortable about fitting the new sprocket. There's a good video on youtube showing how to do the job that shows the same difference in sprockets but he doesn't seem to have picked up on the thickness.

When I did mine I thought there had been the same mistake but turned out it wasn't.

I ordered the chain I wanted from M and P as a kit as it was on a special deal which was cheaper than anywhere else including sprockets.

However the rear sprocket was an unmarked make and the supplied front JT one non-cush drive.
I had already decided on JT sprockets and bought them (cush front) elsewhere. As mentioned in the above link due to an incorrectly supplied chain splitter I negotiated a free spare front sprocket. All 3 supplied front sprockets were/are 520.16 size and the cush one looks bigger but isn't and matched the removed factory sprocket.

Spares - The non-cush (from M and P) and the cush - both 520.


JTs catalogue lists the 520 front, 525 rear and 525 chain for Tiger 800 .... probably designed to allow for better tolerance on sprocket misalignment and wear.

Thanks Stevie.P, I got mine from M & P and have already emailed them. The one supplied has far too much side play and I certainly won't use it. It's a 'Choho' sprocket with no identifying part numbers. The one I removed fits the chain perfectly so hopefully M & P can supply the other cush sprocket. Have to wait for their reply. The rear is fine. Cheers

Would be a good idea to replace the tab washer.

I have the same problem from M and P.
Thinner Chineseium front sprocket won't fit on the splines.
Phoned to complain and they're posting out a JT one.

M & P replaced the incorrect thinner one with a JT cush sprocket straight away for me as well. As it happened two people at M & P dealt with my email and I also received a plain JT sprocket which I will return. The plain replacement would also have been fine. Couldn't fault the service from M & P.
