We are Bagger Drivetrain
We’re just going to get straight to the point: all 1999-2006 baggers ought to have a BAKER DD6 transmission. It’s specifically designed with these bikes in mind. Harley acknowledged the need for a 6 speed with the release of their Cruise Drive a few years ago. There are millions of bikes of this vintage on the fast-moving modern highways that can have a brand new existence with the installation of our Direct Drive 6-Speed.
Our DD6 is finessed for touring model bikes, especially for the later Twin Cam powertrains, as the DD6 mitigates noise amplified in the hollow space between the motor and the tranny. It is the perfect blend of gear ratio, gear type, noise reduction advancements, shift system technology, bearing upgrades and ease of installation. Since the release of the BAKER DD6 in 2003, there have been thousands of satisfied customers world-wide with American touring Big Twins who will attest that it is the premium transmission of choice.
We’ll sell you our normal BAKER Overdrive 6-Speed (OD6) and you’ll enjoy it, but we’d be doing you a disservice as the Drivetrain Authority if we don’t convince you that the DD6 is the best value for your buck. Check out the 6-Speed Builder’s Kit Fact Sheet on the other side of this page to see for yourself how the BAKER DD6 beats the competition hands down. Comparing the cost of time, labor, and additional accessories and factoring in our 5 year warranty, proven dependability, the number of years on the road and our reputation the choice will be clear.
What you get with the DD6:
Pre-assembled gearset, ready to easily install. Install on a Saturday and ride on Sunday!
Helical 4th, 5th and 6th, for a smooth and quiet ride in your cruising gears.
Note: For better get-up-and-go, a 27-tooth compensating sprocket is available as a no-cost option.
Overdrive is obtained through the primary, so this ratio reduces strain on the starter with 14% more torque. The lower RPM in the primary drive reduces resonant noise found in Twin Cam transmission cases at higher primary RPM’s.
Roller detent shift drum, with fixed spindle, eliminates shimming and misalignment.
Finding neutral is very easy with a redundant neutral detent. It also makes installation simpler and less risky to screw up.
Inner primary race/spacer included.
3-point contact shift forks, hard chrome plated for extended life.
Shifter pawl assembly with improved geometry for a perfect response. Includes a built in overshift protection for smooth, precise shifting.
Primary chain included with kit.
1st, 2nd, and 3rd gears are straight cut to prevent lateral tension in those high torque, short-used gear ranges.
Stiff, precise billet aluminum bearing door that offers more bearing-protecting lateral rigidity than any other helical gearset available.
Proprietary fork rod made to bearing grade specifications which eliminates hang-ups.
What you get from the DD6:
The feel of a new bike: The end-all,proven and perfected helical gear design for smooth and silent operation in the cruising gears (4th-6th).
The option to ride hard: Conventional gear shape for strength in the high-torque ranges (1st-3rd) so you can get on it and wick that throttle!
Optimized use of horsepower: 99% efficient in 6th gear with a 400-500 rpm reduction depending on application.
Certain and positive shifting: Fixed spindle shift drum for smooth, low inertia, drum indexing. Anti-overshift ratchet pawl prevents mis-shifts.
Confidence in the ride: Full width BAKER ground gears finished on diamondcoated tooling are strong and dependable.
A good feeling about your investment: 5 year / 50,000 mile BAKER limited warranty keeps you worry free!
An American soul: It’s made in the USA! It’s designed here too. You’ll have a leg up on those riders with cheap, foreign junk.
Easy installation: No grinding to the case required (with very, very rare exceptions). Many competitors’ 6-speed builder’s kits do require grinding.
No exhaust clearance issues: The trap door is the same width as stock.
