Several of us running ZR 900s, 800s and mod versions of both are experiencing a high occurance of belt failure. I expect to munch one or two when running the big bores--over the course of a season, but we can't even get through a day of hard riding without violent belt erruptions. When they go at high speed, they usually punch a hole in the belly pan as well...which is ugly. So far we have been running only the stock Cat belt.
Has anyone tried any other belts? I am hearing good things about the Dayco Ultimax 2. Does Cat offer a "high end" belt that might be a bit tougher?
