Modern Applications

34-Tooth Compensating Sprocket Kit
The 34-Tooth Comp Sprocket Kit is the ultimate solution to late model compensator problems. This kit is engineered with an annular oil distribution system that scavenges primary oil and pumps it with centrifugal force to all radial and axial thrust surfaces. This sprocket will deliver quiet operation, relentless durability, and refined function, effectively smoothing out the inherent power pulsations of the second-generation Twin Cam and M8 motors.
GrudgeBox: 6-Speed Overdrive
The GrudgeBox was engineered with a focus on excessive torque capacity and crisp shifting. All gears are straight-cut in a way that ensures maximum power transfer to the rear wheel. This gearset was designed and geared for the everyday highway riders, speed freaks, and even racers.
Cable-Type Side Cover
The BAKER Cable-Type Side Cover is meticulously crafted for maximum efficiency with minimal waste and precision engineering! Machined from certified 6061-T6 Billet Aluminum, this side cover is seamlessly compatible with both OEM and aftermarket transmissions.
Armored Attitude Adjuster
The BAKER Armored Attitude Adjuster is the ultimate insurance for your motorcycle, providing a tougher manual chain tensioner that maintains ideal slack when your bike is cold. Unlike stock auto tensioners prone to tightening, the Armored Attitude Adjuster ensures a consistent setting, preventing costly damage to critical components. With the ability to confidently set your chain to the proper 5/8”-7/8” (cold) freeplay, ride worry-free and safeguard your investment with BAKER's innovative solution.

Classic Applications

OD6: Overdrive 6-Speed

The original and still unmatched 6-speed design that revolutionized the American V-Twin industry—the BAKER OD6. Built to handle today's powerful big-inch motors with a continuous use rating of up to 165 ft/lbs, it comes in various finish options and configurations. Whether as a complete transmission or a builder’s kit for stock case applications, the OD6 requires minimal modification. It's not just a transmission; it's the epitome of 6-speed excellence by BAKER.

Learn more about the OD6

Fine Tooth Adjustment Kit
The BAKER Primary Chain Adjuster Bracket—a game-changer in precision and reliability. Resembling the stock 39990-01 style bracket, it boasts an impressive 28% more adjuster teeth, allowing for unparalleled control over your primary chain slack. The finer pitch teeth make adjustments a breeze, ensuring a seamless and tailored riding experience.
Smooth Shift Kit
With the introduction of the OD6 back in 1998, a concerted effort was made to significantly improve the shift quality over stock. Audible shift noise and tactile shift clunk were reduced and finding neutral was made easier. That same engineering spirit was used to develop all of our shift kits.
DD6: Direct Drive 6-Speed
The DD6, or Direct Drive 6-speed, excels with straight-cut gears for acceleration, helical gears for a smooth ride, and a 99% efficient direct drive sixth gear. Seamless shifting is guaranteed with a fixed spindle radial ball bearing shift drum, chrome-plated forks, and an anti-overshift BAKER shift pawl. Effortlessly find neutral with a redundant detent. Elevate your ride with the DD6—a top-tier transmission.

Vintage Applications
4-speed Complete Transmission
Experience the perfect blend of old-school charm and modern reliability with the BAKER 4-speed Complete Transmission. Inspired by the iconic Knucklehead era, our transmission mirrors the classic design while addressing original shortcomings. Upgrades like a radial ball bearing, caged needle bearings, and provisions for both electronic and traditional speedometers ensure worry-free performance. The shift detent has been enhanced for a smooth 'snick-pop' action. Embrace the best of both worlds with the BAKER 4-speed—an homage to Harley-Davidson's golden age.
N1 Shift Kits
Experience a game-changing shift with the N1 drum. Expertly crafted from solid steel to prevent catching neutral on a 1-2 upshift. The innovative N1 shift pattern transforms the standard 1-N-2-3-4 to a seamless N-1-2-3-4 configuration. Two Teflon-coated bushings ensure smooth rotation during shifts, offering precision and convenience for riders seeking optimal performance. Say goodbye to accidental neutrals and elevate your shifting experience with the efficiency of the N1 drum.
Klassic Kicker Gears
Over a decade ago, we began producing 6-into-4 transmissions with kickers, facing a challenge in sourcing quality gears. Refusing to compromise, we crafted our own right here in Michigan, now standard in all BAKER 4-speeds, 6-into-4's, and kicker kits. Unlike imported counterparts, our Klassic Kicker Gears roll smoothly, offering unmatched performance. While they come at a price, consider them a lasting investment— the last set you'll ever need.
6-into-4 Complete Transmission
The 6-into-4 transmission is a pinnacle of precision engineering and innovation, introduced over a decade ago to meet the demand for reliable 6-speed transmissions with kicker gears. Featuring the Klassic Kicker Gears, this transmission guarantees smooth operation and durability. This transmission exemplifies a commitment to quality and a decade-long pursuit of excellence in transmission technology.
