Xch
Husqvarna
Researching a 15T front sprocket i find the manual says 520 chain (thought i read 530) so there are several 15T on eBay in both 520 and 530 sizes. Will do some more research and see.
Excellent 13, 14, 15, 16 tooth here and also sprocket and chain sets.

Hot Rod Welding hopefully will be making an X Tank of some size for the Husky if there is enough interest.
Fitted one of these to the X Challenge and it worked great, gave 17 litres all up for over 400 klms.
