Shifting Gears

The Concours 14 uses a return shift 6-speed transmission, allowing smooth and precise gear changes.

When shifting, first close the throttle completely and pull the clutch lever in fully.

This disengages power to the rear wheel. Shift up or down into the next gear using the toe-shift lever.

Shift smoothly without forcing the transmission.

After selecting the desired gear, slowly release the clutch lever while opening the throttle to send power.

Shifting should occur at the following speeds for smooth riding:


1st to 2nd gear at 15 mph
2nd to 3rd gear at 25 mph
3rd to 4th gear at 35 mph
4th to 5th gear at 45 mph
5th to 6th gear at 55 mph


6th to 5th gear at 30 mph
5th to 4th gear at 25 mph
4th to 3rd gear at 20 mph
3rd to 2nd gear at 15 mph
2nd to 1st gear at 15 mph

Warning: Avoid downshifting at excessively high rpm, as this can damage the engine or cause the rear wheel to lose traction. Downshift below 5,000 rpm for each gear.

Clutch System

The Concours 14 uses a hydraulically activated wet multi-disc clutch. No cable adjustment is necessary except for checking the fluid level daily.

If the clutch lever play becomes too great, air bubbles in the line may require bleeding by a dealer mechanic.

The fluid reservoir is marked with upper and lower level lines.

Maintain the correct level for proper operation. If the fluid becomes low, refill with DOT 4 brake fluid and check for any leaks in the clutch line.

Final Drive

The final drive requires approximately 2.5 ounces of oil.

Final drive oil specifications for the Kawasaki Concours 14 are API GL-5 or GL-6 with SAE-90 when riding above 5°C/41°F and SAE-80 when riding below 5°C/41°F.

A well-regarded option for this application is Lucas Oil 80W-90.

An internal c-clip secures the final drive of the Kawasaki Concours 14 and features a sealed o-ring.

The 2022 Kawasaki Concours 14 ABS is equipped with a Tetra-Lever shaft drive for its final drive.

The tetra-lever drive helps minimize jacking in ZG1400/Kawasaki Concours 14.

Transmission Technology

Concours 14 has a seamlessly integrated 6-speed transmission and Tetra-Lever shaft drive.

This combination not only delivers a slick-shifting experience but also eliminates the issue of jacking.

The entire drivetrain is held in place by a lightweight yet rigid aluminum monocoque frame.

Kawasaki has been working on electronically shifted transmissions to integrate into its motorcycles.

The electronic shift mechanism removes the need for a physical link between the rider’s foot and the shift drum.

The patent details a compact and straightforward electronic shift mechanism, translating the movement of the gear lever into a rotation of the shift drum.

The electronic actuator, a key component in this groundbreaking system, rotates the shift drum on an otherwise conventional transmission.

Additionally, the integration of a computer between the rider and the gearshift ensures precise control, minimizing issues such as false neutrals, over-revving, and mistimed gear changes.

Positive Neutral Finder

Between 1st gear and neutral exists a positive neutral finder.

This mechanism prevents accidentally shifting from 1st gear directly into 2nd gear.

To find neutral, shift down into 1st gear from a stop, then lift the lever again. This engages the transmission into neutral.

Gear Position Display

An easy-to-read display shows the currently selected gear, from 1st through 5th gears.

Neutral is indicated by “N” when the transmission is not engaged in any gear.

Overdrive is shown as “OD” on the display.

Riders can use this visual reference to verify they have selected the intended gear and adjust as necessary.

Comparison with other models

Kawasaki Concours 14 boasts a return shift 6-speed transmission, a hydraulically activated wet multi-disc clutch, eliminating the need for cable adjustments, and a positive neutral finder for easy gear selection.

Comparatively, the Yamaha FJR1300 distinguishes itself with a five-speed sequential manual transmission, incorporating a hydraulic wet multi-plate clutch system.

The FJR1300’s transmission stands out for its compact design, contributing to quicker acceleration and sportier performance.

In contrast to its rivals, the FJR1300 includes a 6th gear, enhancing highway mileage and reducing engine speed for efficient cruising.

The BMW K 1600 GT boasts a 6-speed sequential manual, constant-mesh, shaft-drive transmission.

The motorcycle has a multi-plate wet clutch, hydraulically activated, constant-mesh 6-speed gearbox, and helical cut.

Transmission vs Fuel Efficiency

The transmission’s adaptability shines through spirited rides, showcasing a fuel economy advantage over companions like the BMW GS and Yamaha Tracer GT 900.

Many riders report achieving 50 mpg under 70 mph and mid-50s mpg under 60 mph, demonstrating the versatility of the transmission system.

However, it’s essential to note that average fuel economy hovers around 36.5 mpg, with potential drops to the 30s at speeds exceeding 70 mph.

Maintenance Tips

Regularly check the transmission fluid levels and adhere to the manufacturer’s recommended schedule for fluid changes.

Inspect the shift linkage for any signs of wear or damage, addressing issues promptly.

Keep an eye on the clutch system, ensuring proper adjustment and smooth operation.

Stay vigilant about any unusual noises or vibrations during shifting, as they may indicate underlying problems.
