BAKER Overdrive 6-Speed

This is the ORIGINAL 6-speed design that revolutionized the American V-Twin industry. Yet, it's still the best overdrive 6-speed built to this day...hands down. Like the DD5, our OD6 is built to comfortably handle the power from todays big-inch motors. The BAKER OD6 is available with many optional gear ratios to suit your fine-tuning needs.


BAKER Builder's Kits come fully assembled and ready to install into your existing transmission case with no modifications, shimming, or adjustments required.
