You can never have too many holes in your head. Otherwise the really stupid ideas get trapped inside, forcing you to do stupid things, like owning a BigWheel. But i encourage you to get one anyway.
The new Yamahas are running the 1000cc engine out of the R1. I think they produce 100hp at idle. They are heavy as hell, but since they can travel at low Mach numbers, no one seems to care.
