baker the f6f™ for 2007-up h-d® cruise drive™

Reduce Noise:
The answer for your Harley-Davidson Cruise Drive to Upgrade that Noisy 5th Gear. Smooth it up and quiet it down.

Add Strength:
Engine builders are finding the F6F is a necessary part of any moderate, or greater, TC96 engine performance work. With increased power output the axial forces from the helical gears, especially in 2nd and 3rd gear, increase significantly to the point of deforming or breaking the snap rings in the door. The F6F uses a steel plate with 6 screws to positively secure the bearings against the axial thrust forces generated by the helical gears

• Smooth Helical 5th Gear Pair
• Billet Door for Strength and Rigidity
• Heavy-Duty Bearings are 28% Wider than Stock
• Steel Bearing Retaining Plate replaces OEM Snap Ring Design
• BAKER Speedo Recalibration Box
Bad Ass 12-Point ARP Fasteners
• 2-Year BAKER Limited Warranty

30-tooth or 31-tooth h-d® 2006-up cruise drive™ pulleys

Get more oomph from a throttle-wick on your 2007 stock Harley-Davidson FL. Our 30-Tooth or 31-Tooth transmission pulleys effectively ‘gear down’ the bike to optimize the performance in two major ways.

First, you’ll get more torque and power from the take-off gears. This remedies the common criticism of the new bikes being a little sluggish off the line for some riders.

Second, you can utilize the 6th gear at a slower, more reasonable highway speed for a more comfortable RPM. These pulleys bring the cruising gears down a notch for finessing your ride.

Performance details are as follow:

• Increase Rear Wheel Torque (30T- 7% Increase / 31T- 3% Increase)
• Cruising RPM 6th gear (75MPH) 30T @ 2830 / 31T @ 2756
• No more lugging the motor in 6th gear at lower cruising speeds (60-70 MPH)

Note: Will require the use of a 1 tooth shorter belt (For example: H-D p/n 40056-07 is for FL) 2 ¼” special Pulley nut socket required for replacement available from Baker Drivetrain. p/n 94660-07BD

2.25" pulley nut socket wrench

For use on 2006 Dyna and 2007-up Big Twins. Visit the tools page for more info:

DD7: Direct drive 7-speed transmission

The DD7 includes a unique Function-Formed Top Cover

The Baker DD7, Direct Drive 7-Speed is being developed as a direct replacement of the Cruise Drive Harley-Davidson factory 6-speed to improve it in many ways besides just adding another gear.

Stay in the best power range: Many complain that the factory 1st gear is too tall and these bikes feel bogged-down at the stoplight. The DD7 has a shorter 1st gear for improved get-up-and-go.

Because of the shorter first gear and following gear ratios, testers report that the bike feels like motor work has been done. The shift quality is unheard of as well.

The Harley-Davidson factory 6-speed ratios are: 1st (3.34), 2nd (2.30), 3rd (1.71), 4th (1.41), 5th (1.18), 6th (1.00).

The Baker DD7 transmission will have the following ratios: 1st (3.76), 2nd (2.75), 3rd (2.06), 4th (1.55), 5th (1.27), 6th (1.10), 7th (1.00).

Shift smoother: In transmission design low mainshaft weight is always desirable for smooth and quiet shifts. The factory mainshaft is a one-piece design that includes 1st, 2nd, 3rd, and 4th gears. The audible shift clunk in the factory 6-speed is caused by the heavy rotating weight and the resultant high inertia of the 1-piece forged mainshaft. The DD7 mainshaft is light weight and only includes the small 1st gear as an integral part to keep weight down. The shift clunk is absolutely minimized.

Shift smoother yet: Shift smoothness in the factory 6-speed is a definite improvement over the 5-speed. The DD7 is a big improvement over the factory 6-speed because it incorporates a new linear roller ball detent as part of the supplied billet top cover. This linear roller ball detent is similar to the technology first used in Baker TorqueBox transmissions. In the Baker DD7, the shift drum is designed to help the rider find neutral every time, like with all other Baker transmissions.

Ride quieter: The factory 6-speed has straight cut 1st and 5th gears. This yields gear noise in 5th which is a gear that riders spend much time in.The DD7 has straight cut gears in 2^nd and 3^rd. Gears 1, 4-7 are helical. All gears (1-7) have diamond ground tooth profiles.

Additional features include:

• The DD7 Shift System has design cues based on our experience in the drivetrain world.
  • Ease of Finding Neutral
  • Smooth Shifting
  • No Clunks or jerky shifts
• Utilizes ball bearing linear detent in the top cover that was originally designed for the automotive OEM (similar to the Torque Box)
• The DD7 Builder’s kits will come ready to slide in the bike, no case modifications, shimming of the gearset or adjustments required.
• 7th Main Drive Gear, Main Drive Gear Bearing, Main Drive Seal,ncluded in Builder’s kit, to replace 6th main.
• ARP 12pt Bolts for Door, Top Cover and Stock Side Cover
• Re-uses stock shifter pawl. Includes new Main drive gear bearing and seal, door gasket, side cover gasket, and top cover gasket.
• BAKER Re-Cal Box and Leads Included.
• Utilizes F6F Door Bearing Retainer Plate.
• DD7 Door Bearings are 28% Wider Than Stock .
• Trap Door is available in Winkle Black at no additional cost.
