Gear ratio chart

Gear ratio chart - UPDATED

Hi KDX'rs,
I made a gear ratio chart (Excel spread sheet) if anyone wants to download it you can find it at:

http://www.visualize.co.nz/kdx200

And! it has no viruses, how cool is that :nod:

Feel free to download it, use it, and send it to people if you like.

If you think it sucks, or has any mistakes in the math let me know, but i think it's all good.

You can input your own front and rear sprocket sizes, your own revs, and your own tyre/tire rolling circumference and it will give you the speeds in each gear for those revs. It has a chart in Kmh and Mph.

Very nice if you want more bikes to do that with I've got the ratio for several.

I have added a couple of extra pages showing the rev differences which are probably more important than the speed difference. Quite cool how 1 tooth on the front can drop hundreds of revs.

If you have info for a 2003 cr250 or a 2006 yz450f I'd appreciate it if you could post them. thanks

I really only made it because someone was asking about gearing on the KDX.
I may make a generic one in the next few days if I have time, then you could input your own gear ratios and it would show you the speed differences at certain revs and rev differences at certain speeds. Check back in a couple of days.

Is this right? Seems crazy! 35mph at 8000 rpms in 3rd??!?!?! There's no way I am going that fast through the woods.

 

[pdiddy]

Well, playing with this a little more, it makes a little more sense, but wow, I am going a lot faster that I thought I was! 27mph when the KIPS opens in 3rd.

 

[Joburble]

Yea, I am pretty sure the math is good.

What rpm does the kips open?

 

[sr5bidder]

6000rpm +/- ???

Ok for those who wanted a generic chart to work out the ratios of any bike here it is, just go to http://www.visualize.co.nz/kdx200/ and download it. It is much improved, it still has the KDX pages (improved) and it has pages to input your own data for other bikes. It can be used for 5 and 6 gear bikes. If anyone still wants the old one you will have to email me through this forum.

I obviously have too much time. Only five more months until I can ride again! YAY!
