Yes Mr T. I know. Doesn't mean I want to go in one anytime soon.
Maybe bragging rights with a loud hailer outside is the order of the day?

Just go with a smoker - they'd be quite happy outside!
Many years ago I bought a Yamaha XJ550 that was an import from the US - the speedo stopped at 80 mph!
There are very complicated physics that come into play. Aerodynamics become the predominant player over about 130mph IIRC. Over a certain speed the drag is exponentially superior to the power. Not that any of this matters, as I am far too old to travel above 60mph anyway
Yeah like the thinking. Out of interest; why n? Why not X?
Indeed the ///MR will do approx 171 mph and there is no limiter on 5th, that I know of. Not bad for a aging hair salon. Been talked to death over the years on here.Mr Tidy wrote: ↑Tue May 25, 2021 11:17 pmMany years ago I bought a Yamaha XJ550 that was an import from the US - the speedo stopped at 80 mph!
But shortly afterwards I managed to buy a UK model with a knackered engine so got a speedo with 3 figure numbers on it, and might have needed them (on a private road obviously).
My MC seems to be geared for at least 170mph in 5th - maybe one day I'll find out!
Aerodynamic drag is the dominant factor at much lower speeds then 130mph. In simple terms, drag is proportional to the square of the speed (Drag ∝ v2). So basically if you want to go twice as fast you have to work four times harder. e.g. if it takes 10bhp to go 30mph, it takes 40bhp to go 60mph and 160bhp to get to 120mph. This does ignore the drag coefficient of the tyres and the running gear.
