Gear Change Revs

GEH007 · Sep 3, 2007

Hi,

I've just swapped from an 04 fe380 to a new 07 fe 450.

I'm going to fit a Vapor unit, partly for temp checking and partly for showing revs.

There is a facility to set "shift lights" at the revs you determine.

Question is, at what revs is a 450 at the top end of its power or torque band?

Any thoughts would be appreciated.

Thanks.

my duke road racer had a 58mm stroke and max power was at 10,500 revs and red lined at 11,000 revs. you have a 1mm shorter stroke so you could add another 250 revs to both those figures if you wanted.

me? i'd stay at say 9k and 10k.

Thanks for your thoughts Taffy.

I believe they have a limiter in place at "about" 10k.

9k and 10k seems incredibly high, are you not past the "useable" power by then or is it really prducing its best between 9k and 10k?

I value your insight, thanks.

the shift light i should imagine is for your redline and knows nothing of 'best revs' or what the power curve is. so if it's already set at 10k then that's 1k below theoretically what a racing engine would go to but sounds right for you and the longetivity of your engine.

clearly you can't have a double lightin that one says 'best revs' and one that says 'redline'. so it's not incredibly high mate.

if you want to see what incredibly high is: go see a 68mm stroke duke that revs to 12-13k. thats high!

Why would you like to go that hi on RPMÃ‚Â´s, Husabergs are all about torqueÃ‚Â¡Ã‚Â¡Ã‚Â¡, no way I am going to 11250 RPMÃ‚Â´s on mine, there is no need to, just hear your engine, when riding hard I would never put my eyes on a rev indicator, come on is just about feeling.

Taffy is right about the numbers but why doing it???
