'06 tranny ratios

[Transplant2]

This is stuff I wanted to know for a while...so now that I know I will share. If anyone has the 04/05 numbers please post to compare.

Out of the manual:

primary reduction 2.739
final reduction 2.923
~~~~~~~~~~~~~~~~
1st gear 2.230
2nd gear 1.785
3rd gear 1.437
4th gear 1.181
5th gear 0.962
~~~~~~~~~~~~~~~~

Primary reduction 2.739
Final reduction 2.714

1st gear 2.071
2nd gear 1.625
3rd gear 1.333
4th gear 1.120
5th gear .963

Thanks for posting those. I just checked the front sprocket and it's 13 stock. So the 13/38 gives us the 2.923 final. I only got to ride on pavement but it still feels a little tall to me...guess I can get used to it though. :ermm:

I counted also and 13/38 for the 06 still feels a little tall alot better than the 04/05, Once you install a pipe I think it will be perfect.

they had to make internal changes too because 5th gear is about the same as peviously but they made sprocket changes.

guess I ordered a 13 tooth front for nothing. Oh well, I have a spare now.

so, basically this all new gearing for the 06 comes down to honda slapping on a 13 tooth? wow, that was tough.

No...check out the first two posts. The 06 is listed then the 04/05 from colby. The 13 tooth was just an additional change that affects the final reduction.

Anyone have the gearing/reduction #'s on an 04/05 with the 13T sprocket to compare to the 06 stock gearing/reduction?

[cals400ex]

the internal gearing was changed too like i previously said. even with a 13 tooth front on, the 06 has a very very very slightly taller 5th gear. nothing that would be noticable i am sure. the power delivery of the new engine will be noticable though...

This is a little application I wrote -- it will calculate gear ratios, piston speeds, displacement, etc --- and has a lot of data for popular quads preloaded....

Now that is a pretty handy program you have there, Gabe. Thanks.

If someone has primary reduction and individual gear ratio information for a Raptor 700, I'll add that to the program...

BTW, you can run more than one instance of the program for handy comparisons.....
