Nigel, My RD250LC Yamaha was too fast for the traffic in our town. I could never find anywhere I could ride it properly. The only guys who ride really fast around here are the drug-runners. When the police see them., the druggies just do 300 KPH, and say good-bye.Some truth in that IMHO.
Its why I’d never buy a 200bhp+ sports bike, I got tired of riding super fast sports bikes cos I just seemed to spend all my riding time trying to slow the things down. And as soon as I let that focus drop, I’d be doing silly speeds without really realising. Not my idea of fun.
You were obviously not riding motorcycles in the 1960s. In those days, the most advanced four-stroke vertical twin was probably the Hannah Paton. It would he been possible to build a 750cc version, but extremely expensive. And it would have been a pig in a poke, financially And in any case, the two-strokes were always going to be faster. The Commando was probably as good as it was possible to build using the old technology. It was a development of what went ahead of it. Many of the bits were from the Atlas, so the tooling was still relevant. For what it is, the Commando is excellentTHIS is somewhere in the realm of what Norton SHOULD have done with the new Commando. DOHC vertical twin, water cooled, like the rest of the known universe. Sticking with the VERY old pushrod design was doomed before it ever turned a wheel...
When I built my Seeley 850, I never believed in it. But it is amazing - that motor can do so much with so little going for it. I am not bragging when I say I am much faster around the slower parts of race circuits that most others. However it is more the bike which is fast, not me. Over the years, I always raced uncompetitive bikes, so I know how to get a slow one going fast enough to be up in the lead bunch in races.
Have your ever seen a Suzuki SEAR motor which is used in Japanese Autorace events ? It is a four valve DOHC, 500cc vertical twin four stroke. A 750cc version would not be difficult.
