The engine revs are equivalent to your speed in 5th if you multiply it by 100 (with a 15tooth sprocket)

example: the bike is running at 5000rpm in 5th gear @ 50 mph and 6000rpm at 60mph etc - i put a tachometer on the bike and this is true, unfortunately how many revs are too many revs differs slightly from person to person - though most will say don't push it beyond 65 mph (6500 rpm) for too long

Most of the guys here will probably tell you your shifting a bit early thats very similar to how i shift so that sounds about right to me - i don't like to hear the bike scream

I tend to wait till 30 for 4th and 40 for 5th but it depends slightly on how warm the bike is

the best tip for the highway is probably change your 15tooth sprocket for a 16tooth one - it'll handle the higher speeds better without the engine screaming...but it'll loose all (if it had any to begin with) top end torque

*disclaimer* listen to just about everyone else on here before taking any of my advice.... and yes i see that this statement in itself is giving advice
