NEW! Race-Grade Reliability Where It Counts
BAKER Drivetrain’s Race Grade Primary Chain Adjuster Shoes are engineered for riders who demand performance, durability, and long-term reliability from their drivetrain components. Precision-machined from virgin billet Nylon 6-6, these adjuster shoes deliver greater strength, reduced wear, and a significantly longer service life compared to the original cast components.
Designed as direct replacements for H-D part numbers 39976-65B (1965–2000 Big Twin models) and 39976-01 (2001–2006 Big Twin models, excluding the 2006 Dyna), these adjuster shoes offer a high-quality solution now that OEM production has ended. BAKER fills that gap with a proudly U.S.-made alternative that outperforms both stock cast parts and imported cast copies.
Manufactured using modern CNC technology and proven through real-world use, each adjuster shoe delivers consistent performance you can trust—on the street, at the track, and everywhere in between.

85th Annual Daytona Bike Week
Who’s heading to Daytona Bike Week? One of the most iconic motorcycle events of the year is right around the corner. Daytona Bike Week runs from February 27 through March 8, 2026, and it’s always a guaranteed good time.
The week is packed with warm Florida weather, incredible bike shows, live music, unforgettable concerts, and parties that go late into the night. From sunrise rides to after-dark festivities, there’s never a dull moment.
While BAKER Drivetrain won’t be there in person this year, we’re proud to support and be involved with several standout events taking place throughout Daytona Bike Week. Here are a few shows we’re backing during the week.
Jace's Sturgis 1991 FXR
After sitting dormant since 2008, this 1991 FXR is officially back on the road—and what a comeback it is. Jace breathed new life into this bike with a full ground-up refresh.
We were proud to be part of the build with our 5-Speed Transmission Rebuild Kit, N1 Shifter Drum, and Anti-Overshift Ratchet Pawl. One of Jace’s favorite upgrades? The N1 drum. With neutral all the way at the bottom, missed shifts and hunting for neutral are a thing of the past—just clean, confident shifts every time.
Projects like this are exactly why we love what we do—keeping legendary bikes like the FXR alive, shifting better than ever, and built to be ridden. Big respect to Jace and everyone involved in bringing this one back from the dead.

Winter, Women, and Motorcycles
We’ve been digging through the archives this month, and with the cold settling in here in Michigan, this one felt especially fitting. Check out this article Bert wrote for the January/February 2012 issue of Iron Works Magazine.
