I don't understand the 6 speed in the Dyna for 2006.


Dyna 2006
Gear Ratio (overall)
1st 3.337
2nd 2.313
3rd 1.718
4th 1.391
5th 1.175
6th 1.000

Dyna 2005
Gear Ratio (overall)
1st 10.110
2nd 6.958
3rd 4.953
4th 3.862
5th 3.150

Electra Glide 2006
Gear Ratio (overall)
1st 10.110
2nd 6.958
3rd 4.953
4th 3.862
5th 3.150
6th N/A

Why are the ratios so different and why is 6th gear only "1.00 which is only direct drive NOT overdrive?

I noticed that also. I may be wrong but I think one is the tranny gearing and the other the overall driveline gearing. Have no idea why they would do that????

 

The Screamin' Eagle® 6-Speed Transmission says:

The first five gears mimic today's proven five speed ratios. Sixth gear is a true overdrive at a .89:1 ratio, which allows the engine to run at a lower RPM in sixth gear, equating to less vibration and a longer engine life.

.89:1 not 1.00

Any ideas?

By any chance is it cheaper to make it 1:1 than a true overdrive?

 

Road a street bob with the new tranny today. It works well on the highway.
