I agree putting all the power down is a bit difficult, however there are ways to make it easier...
My mate had a bandit 1200, which for 'environmental' reasons had it's power slightly reduced in 1st and 2nd gear (Apparently), and the GSXR 750 does 70mph in 1st gear, with the main kick of power coming in at 40-50mph, so not such a big problem... =)
