Source of Sprockets in Australia
 

I'm looking at changing the sprockets on my XT660R and planning to do this in two steps to check the results - both changes can utilise the standard chain.

Firstly changing the front spocket to 14 teeth - reduction 1 : 3.214
then changing the rear sprocket to 46 teeth - reduction 1 : 3.285

I was thinking about a Supersprox (alloy / steel construction) on the rear but can't seem to find anything for the front listed locally.

Can anyone point me in the right direction ? I'm generally happy to pay a little more for quality.

Pete, I recall reading somewhere that a 14T front sprocket is bad news for chain wear. If you can, you would be better off trying to achieve your chosen ratio by altering just the rear sprocket. Anyone else care to comment?

I have tried most of the different sprocket ratios & found 15/47 to be a good balance for more slow speed throttle control. The 14T is nice for slow speed throttle control but is no good for cruising at 100kph & over.

15/46 is also a good ratio if you do more cruising over 100kph.

I have a brand new 47T rear sprocket in steel if you are looking for one. Depending on how many kms are on your chain you might need to add a link to fit the 47T.
