Is there a place I can find the tranmission ratios of most dirtbikes. I want to compare my 99 400f to a KTM 450exc or Husky TE450. Is there anyway I can find this or do I have just ask in all the forums?

You might try to see if the online service manuals at Yamaha will let you find that info for your YZF. For the Husky, search that forum and then post your question.

Re: Specs...
The KTM site has nothing on it you may have to try the ktm forum and someone could look up thier manual. For the husky check your manual or find an online copy of that manual, again go the the husky forum and they will help.

Heres the yamahas the ktm 4 50 sxwould be very similar and the exc would be taller again.
Check the WR on yamaha for a comparison to the exc if no one can help.

and in the manual

The 2004 revs to 11000 rpm

The top speed you can get an approx by doing the maths

11000rpm
Primary reduction 2.818
Secondary reduction 3.429 with 48/14 sprockets

1st gear 1.929
2nd gear 1.563
3rd gear 1.278
4th gear 1.050
Tyre Diameter 19 110/90 stock, depends what your running

Then deduct 10% or so for slippage and knob distortion

For most setups its around 90-95mph

This will give you an approx top speed.
Any one who tells you top speed is less is a *****.

I was going by:

...and so, I saw no reason to bring up the ratios on the YZ450. I could be tired, it was a long morning. But when I posted, it was about 11:00 am in Southern SoCal on a Monsoon Monday. If you'll forgive me for being tired, I'll forgive you for spelling tire with a "Y" :cry:

That's a British thing, you know.. :cry: :cry:

I will forgive you. But you neednt forgive me as that is how it is spelt in the advanced parts of the western world.
You say tire we say tyre
you say specialize we say specialise
etc etc etc bla bla bla

I convert as much as I can bear back into olden day imperial language but every now and then some twenty first century language or heaven forbid metric numbers slip through to the keeper..

All the best.
