DD7: Direct Drive 7-Speed Builder's Kit



The DD7 upgrades any existing 2006-later big twin 6 speed to a full 7 speed transmission.  The BAKER DD7 is more than just another gear added to the mix for the sake of one-upmanship. That 7th gear enables the motorcycle to now make full use, by way of gear ratio management, of the torque and power put out by the new 96 CI and 110 CI motors rolling off the assembly line in Milwaukee. We did not make this transmission a deep overdrive, rather we shortened 1st gear and tightened up the gears to deliver the riding experience that you were after when you bought your bike. The gear ratios leave you the rider, with the experience of smooth, crisp, continuously pulling acceleration from 1st all the way through 4th gear. Then you are able to start getting into the cruising portion of the program in gears 5th-7th. No big drops in RPM from one gear to the next or lugging the motorcycle off of a stop light, just smooth, uninhibited acceleration.

We did not stop at just fixing the gear ratios. We improved the smoothness and crispness of the shifting by reducing the mainshaft mass by only having 1st gear be a part of the shaft, rather than 1st-4th gears like on the stock unit. Reduction in rotating mass for shift quality is a fact that has been utilized in the automotive world for years. We ditched the stock detent arm and spring assembly from the door in favor of a Linear Detent that decreased friction while increasing smoothness when coupled with the all new shift drum design. We have tightened up the dog teeth on the gears to prevent the loud clacking noise that accompanies every shift on the factory 6 speed. Through the use of a billet bearing door, 28% wider bearings in the door, steel bearing retainer plates and full width gears, the durability and strength of our unit is a drastic improvement. By utilizing fully diamond ground, helical gears in 1st & 4th-7th we are able to deliver a much quieter riding experience. While 2nd and 3rd gears are diamond ground, spur gears to handle the peak torque that is reached in that range.

NOTE: To upgrade your older DD7 to the new Tapered Bearing style main drive gear bearing you must purchase PN 740-67. The current kit comes standard with the Tapered Bearing Kit.

    Optional Cruise Drive Pulleys: Along with the launch of the Cruise Drive transmission on the 2006 Dyna models, the factory started using bigger diameter splines on the output gear. This change made us tool up a new pulley to meet the tuning needs of our performance-minded customers. Pulleys are available in 31 Tooth configurations. 
    PN 31T-07 (31 tooth)

    Re-flash ECM: The DD7 has different gear ratios than the stock transmission (except DD7 7th gear is the same as stock 6th gear, 1:1). This changes the input to the ECM. The gear indicator and cruise control may only operate in 7th gear. To correct the gear indicator in all gears and enable cruise control, an ECM re-flash is required. Existing tuners must have an option to modify transmission gear ratios in order to re-flash the ECM.

    BAKER Drivetrain offers re-flash values for Powervision, ThunderMax, TTS, and Techno Research tuners.  Click here for the DD7 Recalibration Values

    Shift System

    The shift drum utilizes many of the same features we have learned over the years, and incorporated into our other designs. Make the shift drum as light as possible, close tolerance design of the drum tracks matched with specific angles of the drum tracks ‘events'; make for smooth and positive shifting. Our specifically designed neutral position on the shift drum detent clover leaf make it easy to find neutral, every time. The close tolerance drum design paired with the gearset lay out, yields tight, repeatable dog tooth gaps that are not possible with mass production, cast shift drum designs used on the stock transmission.The linear detent, a design first used in the OEM car world. We were the first to introduce it to the V-Twin world on the Torque Box transmissions, and we have used it on the DD7 as well. It produces the lowest friction possible, with the controlled nature of using a coil spring in a strictly linear manner. The amount of precise control possible with a linear detent, can not be realized with the stock scissor spring and lever wheel detent design found on the stock gearset. All of these changes along with the billet steel machined, hard chrome plated shift forks, make it the smoothest transmission we have made to date.

    Gearset

    The factory 6 speed has a 1 piece mainshaft with gears 1-4 machined out of one forging. This is easier and cheaper for high volume manufacturing, but yields a mainshaft that weighs over 5 lbs. This heavy one piece design is largely responsible for the clunk heard on every shift. This heavy rotating mass crashes into the gears on every shift. The DD7 has a 1 piece mainshaft (8620 steel) that only incorporates the small diameter 1st gear and weighs 3 lbs less than the stock unit. Whereas the stock gearsets utilizes a straight cut gear for 1st, and helical for 2-6, the DD7 uses straight cut 2 and 3rd gears, with the remainder being of a helical design. The largest amount of torque is put to the ground in 2nd 3rd gear, and straight cut gears handle that power the best. There is a not a lot of cruising going on in these gears, so the strength benefit of straight cut teeth outweighs the noise reduction factor inherent with a helical tooth design. The stock gears have tooth profiles that are cut on a shaper machine after heat treat, the BAKER gears are shaper cut before heat treat then precision ground with diamond coated tooling after heat treat (58-62 Rockwell ‘C’). This extra steps ensures not only a quieter gear pair, but enables much tighter backlash control. Further enhancements have been made to the male-female dog tooth pocket interactions, the tightened up radial gap on our design reduces the on-off throttle lag time and gear clunk noise found on the stock transmission.

    Bearing Door Assembly

    The stock bearing door is cast aluminum, the DD7 door is machined from virgin billet 6061-T6 aluminum.  Billet is stronger and this instance is no different. The stock gearset’s cause a phenomenon we call ‘Ghost Lever’.  Starting from low RPM’s in 2nd or 3rd gear go right to WOT and then get off the throttle.  Watch the clutch lever walk in and out from the handlebar. This is the shafts in the transmission walking left and right in the case due to the flex of the bearing door and the skinny stock door bearings. We use 28% wider roller bearings in the door and used a cold rolled 1045 steel plate to hold them in place, rather than the stock snap rings. No more Ghost Lever and much more power (up to 160 ft-lbs) can be thrown at it without the bearings breaking a sweat.

    Fitment Note: Cruise Control will only work in 7th gear and the Red Line will be 5200 RPM with the DD7 on Throttle-By-Wire bikes equipped with stock ECM’s. No other motorcycle functions are affected in these instances. The 6th gear indicator light will come on when the DD7 is shifted into 7th on all models and all ECM’s. Aftermarket tuners such as Daytona Twin Tec and TTS-Mastertune will allow cruise to function in all gears, like stock, on Throttle-By-Wire bikes when coupled with the DD7 gearset. Dynojet can also flash your stock ECM to adjust the cruise control the cruise and red line, while still allowing the ECM to work with piggy back units like Power Commander. Any questions on this, please give our tech line a call. 

    Recommended Fluid Level

    Picking the right transmission fluid ensures the life and durability of your transmission, that’s why BAKER recommends a fully synthetic GL-5 rated gear weight oil of 75W-140.

    • What model motorcycle do you ride? 07 Ultra

    Indestructible

    I purchased the DD7 and attitude adjuster for my 07 Ultra with stage 1 kit..back in 2010 after destroying the 6 speed twice under warranty. I told the guy at Baker I was going to try and break it , he said go ahead ! I have 90k mikes on my bike 70k on the DD7. Wide open throttle shifts. I pull a small trailer with camping gear often. It is INDESTRUCTIBLE!!!

    DD7

    Easy enough install for this motorcycle shop teacher. Honest review since I have put some road miles on my 09 FLHX. Super smooth shifts, enjoy the lower ratio first gear. Engine feels great pulling with the close ratio spread of the DD7. Enjoy gears 5,6&7 for cruising, never feels like I’m in between gears lugging the engine or over revving. One of the absolute best upgrades I have made to this motorcycle. Others being, Attitude Adjuster, 1.5 plus oil pan, Truss shift lever, high torque bearing and Baker heavy duty clutch release bearing kit. Happy with all Baker Drivetrain Products. Made a nice factory FLHX even a whole lot nicer and more dependable!!

    Lower 1st gear

    Really like my bike now that I installed the DD7. I wanted a lower 1st gear and couldn't be happier. Installation was smooth with very detailed instructions. I also used the spectro oils that were recommended.

    Great Transmission

    This is a great transmission. I haven't had time to put many miles on it yet but having less RPM loss between gears is nice. Also the lower first gear is nice that you don't have to lug it when starting out from a stop.
