I just bought PGR4 for Xbox 360. One of the first few vehicles you're allowed to drive is a Buell motorcycle. I hope more Buell models will be available once I get further into the game. [up]
The driving is pretty sweet. You can drag your knee in tight turns. It's pretty realistic IMO. If you wreck a car you can correct yourself and get going sooner, if you wreck your bike you actually fall off and it takes a minute to get going again. I would like to see a realistic death wobble situation, but it's still cool.
The death wobble and the tank slap are closely related terms. I first learned about the death wobble racing my scooter/moped (49cc) when I was 14. I drilled out the exhaust and added octane booster to race other kids around the block. One day I beat some kid on a Tomos and as I passed him I ripped the front end up only to land with my front wheel crooked. The wobble started and next thing I knew my scooter and I were sliding on the concrete.
