If you can drive a motorcycle with a 150HP engine thousands of miles, for months at a time, without needing to touch the drive belt, then I think we are safe with the same belt system on our 2HP robots, running a couple hundred 2 minute matches throughout the season.

The big difference though is that the motorcycle isn't subject to the same forces that a robot is when it's on a field in competition. You don't see too many motorcycles getting side impact crashes and still running properly. Robots get hit a lot, so they need a system that is more likely to still run properly after being nailed in the side while running.
If a robot wasn't subject to bumps and bruises that come with moving around on a playing field, I'd have no doubt that they'd be able to run for a long time. But they are subject to those forces so things are more likely to break.
