A road race bike that weighs 100kg, and makes 80Hp will easily run rings around one.
But most road race bikes (bar 125s) weight heaps, and make very little power to weight ratio.
And if i put long forks and a extended swingarm on my RS, with some Dirt tyres, and a really low ratio gear box.. It would probably do pretty weill against the other 125 MX bikes.
For lap times, An RS125 ridden well, will/should smoke any motards on the tarmac
