Has anyone tried, or know somebody who has done the DD7 upgrade? It looks like its around $3400. My over the road tractor only had a 10speed!

 

Do you need a new trans or are you just looking to "upgrade"?

Reason I'm asking is that I "upgraded" my 2000 Ultra T/C 88 from the stock 5 spd to a Baker DD6, mainly because the bike was cranking 3,500 RPM's in 5th gear at 80 MPH (which I thought was too high).

Looking back, I don't think that was a good idea.
With the DD6 installed, the stock T/C 88 didn't have the guts to pull it in 6th under 65 so I "upgraded" the engine with a "1550" big bore kit and that really made a huge difference!
The downside to all of this was that I started riding faster (as the bike ran so much easier) but then I used more fuel!
The upside was that I could manage to keep up with my wife who rides a Heritage Softail.

In hindsight, I would have been better off with the stock 5 spd cruising at 70 MPH and running 3,000 RPM's.

 

$3400.... are you freakin kidding me? Mighty pricey for a tranny. Is that the off the shelf price or is that installed?

 

Search this forum under DD7 , you'll find out what ya need.

 

....and Baker is a site sponsor who contribute in the Tech section, if you have any queries.

 

Not sure why you would need a DD7, but for 3400 bucks you could do a hell of a big bore kit

 

Those kind of upgrades are really just for peeps with more money than they know what to do with. And that's all good if you've got it but in my mind, there is no rational reason for it. It would take a zillion years to realize any payback from gas mileage, you are spending big money to reduce wear on an engine when you could replace the engine for less, if it's comfort on the road you could take that money and your current bike and buy a new one that does what you want. Other than bragging rights to a seven speed I just don't see it. But if it makes you happy and you have the bucks then, hooah!

I agree its too high! If I was going to do it, it would be a up grade, my B6 is doing fine. $3400 was installed but still too high.

 

Yeah, Baker is real proud of their stuff.

 

$3400......Wowza.
