bloody hell lads i did 100 in my van on my way home from work this week! ive done the ton on my 550 f2 and it was not pleasant. i only did it so i could say i had but to be honest apart from being a bit of a white knuckle job (and uk roads are v,busy) it didnt feel like the thing to be doing on a 30 odd year old bike!!! the old bugger has earned a bit more respect than that...
