I am running the stock 14/48 on my '94 XR600R and I want to go with 14/53 since I can't find a 13 tooth front on any web sites. the stock chain is a 110 links, I am looking for the length I'll need for a 14/53 setup. I can only find 14 and 15 tooth fronts for the 600R. There are plenty of options for the XR650R but not the 600. Any help would be appreciated.
