Our BAKER DD5 is not just a replacement for the stock 5-Speed. Whether you're going down the drag strip or you're cruising down the road, the torque capacity, long term durability and shift quality are greatly improved over stock. Will handle up to 200 H.P. no problem.

S&S started some shit. A couple years ago they took the classic Shovel, Pan, and Knuckle engine designs and re-birthed them with many modern improvements to address leaks, durability, reliability, and performance. So we took the hint and re-engineered the venerable ratchet top 4-speed with that...

We bought a new 2007 FL to use for 7-speed transmission development work. The first thing we noticed was how hot the damn thing ran. In traffic, we could see those little heat wave squiggle lines (maybe a flashback) coming off the motor. The 4-qt capacity, unchanged since 1993 (when the 80" motor...

From an engineering standpoint, it is difficult to design a machine or mechanism that achieves multiple objectives with minimal compromise. An amphibious car is a good example. A few have been manufactured over the years, and they achieved the goal of navigating on land and water, but did neither...

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...

THE ORIGINAL 6-SPEED TRANSMISSION 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. Our OD6 is built to comfortably handle the power from todays big-inch motors. This transmission is rated...

Our F5K is designed to fit on bikes fitted with our DD5 or Factory 5-Speed bikes. We know bolt on kicker kits are nothing new. Over the years many have come and gone for one common reason: they all relied on a ratchet hub or shaft extension that screwed on to the end of the mainshaft in place of...

The torque output of an engine is proportional to the bore and stroke. Engines make torque and drivetrain components take torque. It is torque, not horsepower that destroys clutches, transmissions and drive belts. The torque capacity of a transmission is proportional to the gear width and the...
