I'll never get this thing about silly speeds and massive power on public roads with all the dickheads and old ladies in the way    

I've always heard good things about CB500s

An oil cooled engine won't pull 10800 in top.....unless it's very low, they drop away after 10k.

The point of mph/1000 revs is that you can work out what would work for your engine, where the torque is, revs at cruise speeds etc. Our engines are vibey around 5,500 rpm, so it's good to avoid that. A 16 mph per 1000 top gear gives 80 mph at 5000 revs - relatively relaxed and away from the worst of the buzz. Road gearing is a compromise and depends what you want, acceleration,  or more relaxed cruising.

I'm well in my 50s and still a hooligan at heart, more considerate these days, but my bike is a bad influence

Just for fun, here's a side by side comparison of the 5 speed and 6 speed through the gears. Not so relevant on a street bike but very beneficial on a track bike. Same tyre size and same top speed at 10,8000 in kmh. I can't get my head around mph . Can clearly see what the motor is doing through the gears
