yeh as above, not sure about the yam but cbr is 6spd, 4 stroke twin and weighs about 130kg's. top speed about 75mph and 0-60mph in about 7/8 secs cost £15 a year in rfl, cost less than £10 quid to fill up and our new cbf125 engine is getting 143mpg so fuel economy is wicked to.. and you have honda build quality unlike yam, kwak and suzuki haha!
