Has anybody used Niche rear sprockets or know of any problems with them? Can anyone tell me what is the design difference between Yamaha sprockets 248-25445-10 and 248-25445-11. They both show to fit the CT3 but the last numbers designate a design change?

A -10 is black and a -11 is silver in color?

 

No there is -00 after each number which designates the color code . The first 2 numbers after the part description tells how many redesigns there have been. so the -10 had 10 design changes and the newer -11 has had 11 design changes. I'm not sure if anyone with a ct3 has used the -10. Not sure what the last design change was. Looking for some info on this. Thanks for the reply. The part codes I believe are listed in the library.

There is an article under " Decoding Yamaha part numbers" which tells us the meaning of the codes. It is posted in the  - How to Articles. Hopes this helps-
