My AR125 did 90mph on the clock, once, on a flat, wind behind me....

I miss my AR...

i just refuse to believe that a 50cc roadbike will do 90mph two up. its completely outside the capabilitys of the machine. a de restricted 125 with 25-30 ish bhp might pull a genuine 90-95mph with a long runup, and theres no way on earth a ped, even with an 80cc big bore kit is putting over 20 ponies on the road.
never said it was two up. When i bought it the lad i got it from said it did 85/90 i just laughed at him, was laughin at other side of my face when i had a go on it lol. I know what ur saying i wouldnt have believed it either but there ya go lol.

i went o college with simon beck (former manx gp winner, now sadly dead , killed on the island a few years back) and he used to race a kriedler, it had i think he said, either 12 or 18 gears and a real razor blade thin powerband, that could crack the ton regularly, but it was a full on race bike, albeit one that was light enough to be picked up with one hand, a jewel like tiny little bike, but as for a 90mph road bike? nahhhhh i still think not.
as for the first uk tested ton up 250, if we arent talking japanese, then we must be talking about something italian perhaps? or even one of the highly tuned eastern european strokers? but i think italian, ducati or even a morini, in fact i think i recall a morini with an unpronounsable italian name springs vaguely to mind, but dont ask me to spell it!!
