Is there any diff in power between the 160bhp R1 engine and the 180bhp R1 engine? Thanks

Probably not, but the torque may differ. Don't quote me on this though, don't know much about bike engnes >_<

Depends where it makes those 20 horses if it doesn't rev more then it'll likely be proportionally more torque throughout the rev range.
Considering how much bike engines rev the difference won't be a lot till you really get it spinning.

Why not? I change gear when the valves bounce.

The only way it gets to make twice as much power as an A series is to run to twice the revs.

find some power graphs from the different year of bike and compare at what revs the engine makes its power there must be plenty or proud r1 owners on the internet posting up jpegs of there graphs... oh and i doubt any r1's make what yamaha claim they make

Coming more from a bike background than mini one. On a bike twenty bhp is a huge difference especially when its on/in something that weighs around 170kg, there will be more torque from lower in the rev range and a smoother power delivery all the way upto the 14000 rev limit and you will use it cause these things start to pick up after 9000. Most bikers rave about power comanders and race exhaust systems when in reality they are only gaining about 10bhp extra, but this 10bhp can definatley be felt.

The manufacturers measure the bhp from the crank and not the wheels and also include the ram air effect into a preasurized air box, which most of us threw away, so were down on the bhp straight away. I assume the 180bhp engine is a later one with revised and lighter internals, fuel injection etc...get the 180bhp.It will be more powerful, but it wont be 180 nooooo waaaay.
