Did the bike explode in a ball of flames? You're not suppose to go over 3k as it wears out the tacho.

You don't need a redline, that's what the rev limiter is for ::)

So you are going to tell you're insurance company that " I was just wheel spinning away from the traffic lights when it gripped unexpectedly...." I think I know what they will say, probably along the lines of "no" but with more F's involved.  :lol

You can even go 15 posts back to my first guess  :D


Oh, and my gears don't clunk from 1st to 2nd, mainly neutral to 1st.

In case anybody wanted slightly more accurate information/speed at different revs or gears, this website is pretty great:
http://www.gearingcommander.com/


Just chuck in your bike's make, model and version, switch is over to mph, then put the rpm in the m.p.rpm box - easy!

It's all here on a nice sheet which also shows the effects of changing sprockets.

That says a standard 155mph, that ain't right?

Its entirely possible that IF the bike were to ever reach 12,500 RPM in 6th it would be travelling at 155mph... it just won't ever get there because it doesn't have the power...

A rather pointless figure then?

I think its there more for consistency - besides, there may be other bikes that the gearing also represents which have the extra power to achieve such a figure?

Also, if you change the gearing enough, the 12,500 RPM in 6th can come down to below Yamaha's quoted top speed for the bike - not a useless figure then ;)

Don't forget the added turbo and the 1:3 gradient down hill as well  :lol

also dont forget the wind - because at 12,500 rpm and 155mph I will be making quite a lot of it !

Wind and gradient don't make a different to gearning ratios... they make a difference to the maximum speed achievable under those conditions as they are a function of power, but it won't affect the RPM for a given Speed and Gear

I have seen on the speedo just under 150 mph on the 600 so about about 135 mph true speed, i dont think a half faired 600 would pull a true 155 mph ( did get 168 mph on my R6 speedo reading ( 1999 model) :evil

I've had 135mph with a passenger on as well, and if it wasn't for a pesky car changing lanes about a third of a mile up ahead i'd have gone quicker.
Bloody thoughtless these car drivers.  :lol

Yeah, I'm not good at judging internet humour unfortunately... sorry :P

I will generally always go with "There is no accounting for human stupidity" and just assume the worse case scenario :P
