    Baker DD7 Direct 7-Speed Transmission Gear Set for Harley Zoom



    The Baker Dd7, Direct Drive 7-Speed Is Being Developed As A Direct Replacement Of The Cruise Drive Harley-Davidson Factory 6-Speed To Improve It In Many Ways Besides Just Adding Another Gear.

    Stay In The Best Power Range: Many Complain That The Factory 1St Gear Is Too Tall And These Bikes Feel Bogged-Down At The Stoplight. The Dd7 Has A Shorter 1St Gear For Improved Get-Up-And-Go.

    Because Of The Shorter First Gear And Following Gear Ratios, Testers Report That The Bike Feels Like Motor Work Has Been Done. The Shift Quality Is Unheard Of As Well.

    The Harley-Davidson Factory 6-Speed Ratios Are:
    1St (3.34), 2Nd (2.30), 3Rd (1.71), 4Th (1.41), 5Th (1.18), 6Th (1.00).

    The Baker Dd7 Transmission Will Have The Following Ratios:
    1St (3.76), 2Nd (2.75), 3Rd (2.06), 4Th (1.55), 5Th (1.27), 6Th (1.10), 7Th (1.00).

    Shift Smoother: In Transmission Design Low Mainshaft Weight Is Always Desirable For Smooth And Quiet Shifts. The Factory Mainshaft Is A One-Piece Design That Includes 1St, 2Nd, 3Rd, And 4Th Gears. The Audible Shift Clunk In The Factory 6-Speed Is Caused By The Heavy Rotating Weight And The Resultant High Inertia Of The 1-Piece Forged Mainshaft. The Dd7 Mainshaft Is Light Weight And Only Includes The Small 1St Gear As An Integral Part To Keep Weight Down. The Shift Clunk Is Absolutely Minimized.

    Shift Smoother Yet: Shift Smoothness In The Factory 6-Speed Is A Definite Improvement Over The 5-Speed. The Dd7 Is A Big Improvement Over The Factory 6-Speed Because It Incorporates A New Linear Roller Ball Detent As Part Of The Supplied Billet Top Cover. This Linear Roller Ball Detent Is Similar To The Technology First Used In Baker Torquebox Transmissions. In The Baker Dd7, The Shift Drum Is Designed To Help The Rider Find Neutral Every Time, Like With All Other Baker Transmissions.

    Ride Quieter: The Factory 6-Speed Has Straight Cut 1St And 5Th Gears. This Yields Gear Noise In 5Th Which Is A Gear That Riders Spend Much Time In.The Dd7 Has Straight Cut Gears In 2Nd And 3Rd. Gears 1, 4-7 Are Helical. All Gears (1-7) Have Diamond Ground Tooth Profiles.
    &Nbsp;Additional Features Include:
