Most motorcycle problems are caused by the nut that connects the handlebars to the saddle.

speed to revs

Post by jonny10 on Tue 27 Oct 2015, 11:04 pm

On the country roads round where I am, very rarely do I get a chance to go over 6k-ish, which gives between 80-85mph. I hate m/way riding and avoid it if I can 'cos of the boredom, so I hardly ever seem to get to that "sweet spot" of 7-8k that people talk about. 
Just wondrin, on a good fast bit of reasonably level road where you can open her up a bit, what kind of speed will your bike do at 6k, 7k and 8k?...and above this? Where does she top out -10k?

Yeah but go over 6k in 2nd, 3rd and 4th on the country roads and see what happens!

They top out at 10.5k (not in 6th, probably, however) but on my bike the torque starts slightly tailing off after 9.5k and is best 7-9.5k so I fairly rarely go that high these days. 9.5k is where peak power occurs anyway. I believe though that for the fastest acceleration possible 'on the drag strip' it's certainly worth reaching redline in 1st, and probably 2nd, because of the gear ratio spacings and keeping it in the band...

Oh definitely. As long as it's got enough oil and is warmed up, rag it all you like. I've put 125,000 miles on one and just under 40,000 on another doing just that, at least half of the time.

You're only really going to use 2nd and 3rd on those lovely twisty country roads. The bike loves the revs!

I run higher than standard gearing but out on the twisties  keep engine revving 5/9 K if working real hard just run it to the rev limiter (11k7) and it drops back close to max power !

I always run my CB500's to the limiter when riding with bigger bikes with fast riders not blown one yet
Last bike had 96k on it when stolen this bike got  65k but the engine was swapped at 18 K  with a 98K used one so engine done 145K Smokes when thrashed :-))

I find if I roll around at Low revs the bike uses more fuel than if I keep it turning at over 6K
