How dare they've ridicule the M45, its a fine piece of tarmac especially the bit between Kilsby and Barby, slight downhill and straight for about 2 miles. I definitely didn't see 145 (mph or kph can't remember) in my V6 Cavalier;terrifying I must admit Don't know about the CB at all but do know my old 600 Diversion would run out of puff when I got above 80 or so.Most of the time it was adequate but I did find myself with the throttle wide open and nowt in reserve on occasion when overtaking.That's why I went to a litre bike, for safety... Run out at 80 how many pies did you eat, the original had a half decent standing 1/4 for size of it and top speed well over a 110 It was a memorable occasion overtaking a Honda S2000 that did it, went to go by him about 70 and he accelerated, I was on the wrong side of the road with the divvy pinned and only just scraped by seeing 3 figures when I finally passed him. It was a half decent bike otherwise. I bought the FZR thou soon after and celebrated by eating a couple more pies,
