BAKER RIGHT SIDE DRIVE TRANSMISSION ASSEMBLIES FOR CUSTOM FRAME BIG TWIN

Used with a right side drive Big Twin frame these transmissions will allow the use of a 250 series wide tire and still be able to run a 1 1/2" wide drive belt. The right side drive was developed to use this massive size tire without offsetting the engine to the left side of the frame. Not only does it keep the weight mass centralized in the frame it separates the gyroscopic effect of the primary drive and the secondary drive to each side of the motorcycle.
Features

The 5 speed version includes standard ratio gears and is best suited for stock through moderately modified engines.
The 6 speed version includes standard ratio 1st through 5th gears with a .86:1 ratio overdrive. The 6 speed is best suited for a large displacement engine.
For strength all gears are full width and are manufactured by Andrews.
To eliminate a weak area normally associated with the 1980/Later type transmission, Baker has incorporated the countershaft and the countershaft's 5th gear into one piece. Chrome plated hydraulic clutch actuator/pulley cover. Chrome plated top cover with 1980/1997 type neutral switch. Fully polished transmission case manufactured by S&S. Chrome plated access door CNC machined from 6061-T6 billet aluminum. Compatible with the OE speedometer sensor. Includes 32 tooth transmission pulley.
Splined mainshaft is designed for 1990/Later style clutch. Smooth effortless shifting is accomplished by several factors:
All gear dogs have lead-in ramps.
The lighter weight of the shift drum reduces rotating inertia and has redesigned for pin grooves.
Shift forks that are made from billet steel then hard chrome plated.
Roller with torsion type spring for the shift drum detent instead of the OE type plunger/coil spring detent.
A Manufacturer's Statement of Origin is included.

BAKER DRIVETRAIN 6 INTO 4 TRANSMISSION FOR YOUR SHOVELHEAD

Baker's 6-into-4 transmission is a direct replacement for the 1970-E84 4-speed, available with or without the time-honored 1936-84 style kicker. In a 4-speed, 4th gear is 1:1. Baker's Shovelhead 6-speed overdrive has a 1:1 5th gear and a .86 6th; good for a 500 RPM reduction in cruising RPM on the highway.

6 into 4 with Kicker ...$3080.00 including shipping*

6 into 4 without Kicker ...$2855.00 including shipping*

6 into 4 pulley 33 tooth (BD-32181S) ...$239.50 including shipping*

INSTALLATION NOTICE: The transmission bolts directly to your stock frame and your stock inner primary bolts right up. Due to the extended length of the transmission on the kicker side the rear exhaust pipe, oil tank and electric starter mounting brackets may have to be modified. Some inner primary covers require modification to clear the main drive nut. Some electric starter installations require modification of the transmission case for clearance. There is no speedo cable provision in the tranny case, but you can relocate the speedo cable to the front wheel. Another option is to convert over to electonic speedometer. An electronic speed sensor provision is in the door and it accepts factory 1994-Later style sensors.

These are special order items, please call to order.  These are built to order and take approx. 2 weeks. No returns on special orders. Toll free order line: 1-866-889-7828.

NEW! BAKER BILLET SERIES TRANSMISSIONS

Baker set out to achieve superior function with no compromises in form AND beautiful form with no compromises in function and they nailed it. The new BAKER Billet Series transmissions for Evo-based Softail applications are very simply the best transmissions that money can buy, period. Here’s why:
TOP cover and trap door profiles perfectly match that of the case.
6-BOLT doweled top cover.
NO mold parting lines or mismatched areas due to casting.
NO circumcised cast case "dingy" profile, near the trap door. The “barrel” of the tranny case blends perfectly into the trap door profile.
THE case is effectively “shrink-wrapped” around the “envelope” of the gears to yield the smallest, tidiest tranny case available.
STRUCTURAL rigidity gains from the billet case and doweled top cover yielded significant NVH (noise & vibration harshness) improvements and a reduction in air born noise. English translation: It is the smoothest and quietest shifting transmission available, period.
AVAILABLE with the speed sensor hole in the door, case, or neither.
AVAILABLE with or without neutral switch.
