Paul, the only things I could see clearly in the pictures are the lack of number plate brackets on the rear diagonals and the lacke of a rear seat support loop. One of the other really easy ones is if it has the gusseting box on the front frame tubes below the steering head. The street frames had it and the Manx frames didn't. Less obvious, at least at first glance, the Manx frames were all Sifbronze welded (brazed, if you prefer), while the production frames were all electric welded. Even less obvious, the radius at the rear of the top main frame tubes is larger on the Manx than on the production frames. Another fairly obvious one is that Manx frames had a full rear loop behind the seat with a bracket for the fender, which the production frames did not. There are probably other differences, but these are the ones that I recall.

It does have the gusseting boxed in so it is a Wideline Atlas frame, thank you!

What is the good of a 100 BHP motor, if the bike dies the first time it hits a head-wind. Many two-strokes are like that - they have heaps of horsepower but no substance. If you turn into a head-wind, they feel as though they have stopped. Once the heavy Norton crank is spinning high, nothing stops it. It is a different type of power. The problem comes when you try to make it useful If you have tons of torque, the gearbox converts it into top end go. I doubt my motor turns out more than 70 BHP at the rear wheel, yet I can keep up with the methanol-fuelled 1100cc CB750 Hondas. It is a matter of doing more with less. The crank in the Honda is probably fairly light, so they need to be kept revving very high to make good power. That means they are different in corners, where you need to be more careful.

If you want to go really slow with a Commando, try racing with a standard wide ratio gearbox. and a single disc front brake.

I've done both


Ha I wrote that & then I thought I've done all three.
Though mostly like the football pools any two from three.
