[QUOTE="lwsmithjr, post: 1233310, member: 35074"] I think he meant down on the front.....going smaller on the front decreases the bend radius on the chain and causes it to wear faster. 13/50 was stock on the '02 - '04 CRF450's. In '05 Honda dropped two teeth off the back without changing internal ratios. On my '06, I preferred the 50 rear. Made 3rd gear more useable on the track and didn't have to shift as much. As for sprocket ratios, if you go [B]UP[/B] one tooth on the front, that would be like going [B]DOWN[/B] 3 1/2 teeth on the rear. I'd take BSWIFT's advice....... [/QUOTE]
