A buddy of mine races the USCC circuit on a 05 MXZ 600 adrenaline and has been breaking chains at nearly every race. He wants to put a TEAM HYVO gear in but TEAM and the race department say they are out until next year. So I was wondering if anyone knows of someone who might have 43 tooth HYVO gear for sale? Any information (phone #'s, websites, etc) would be greatly appreciated.
