1994 Raid sprockets/chain
Permalink  
 

Hi

I have just joined the forum and have been having a good look round for sprocket/chain info but haven't found anything that matches the setup on my bike.  It's a 1994 Raid (4GY3) with an 18T front sprocket, 57T rear sprocket and what I take to be a 428 -134 chain.  The chain needs replacing and I guess I should change sprockets at the same time - the question is to what? 

Lots of people here talk about 13/14T front sprockets and 48/52T rear sprockets and 520 chains but I have absolutely no idea what the effects of any change to my bike would be?  Another question may be where can I get an 18/57 sprocket combination from if I want to stay with the original spec?

Thanks for any help

Pete

Hi Pete and welcome to the forum!

What are you going to use the TTR for - road, off road or a combination of both? If you are planning to do a reasonable amount of off-tarmac riding then the investment in a 520 O ring chain and matching sprockets would be worthwhile.

If you retain the existing set up then I am sure there will be some Raid owners on here who have swapped out their original chain and sprocket sets and might have some good s/h ones available.

Otherwise I am sure you will be able to get original spec new sprockets from a Yamaha dealer. 

Brian

I have looked through my "sprocket box" and have a good 57 rear sprocket which you are welcome to for the cost of p&p - about £5. No front sprocket or chain - sorry!

Email me at sales@totallyttrs.com if you are interested.

Cheers

Brian

 Thanks Brian - I think I'll wait to see what general info I get back.  It may be that I ought to think about changing sprocket-sizes.

 

Cheers
