Engine
Clutch
The Dirt Racer Complete Clutch Rebuild Kit is the ultimate package for your Yamaha, here's why:
'Stack Height' is the all important factor when renewing a clutch and riders are always best to buy a complete kit instead of separate single plates as sold by manufacturers. Replacing just the worn plate (or plates) may not even get close to rebuilding your clutch to its original stack height and all you get is clutch slip and the job has to be done again.
- Complete set of stack height controlled anti-swell friction plates
- The friction plates are forged allow with wide "Ear" construction to spread the load in the clutch basket and prevent "Dogging" (when the ears cut into the allow clutch basket) which causes a rough clutch, promotes slippage plus it ruins an expensive part of your engine
- EBC unique alloy article impregnated clutch facings that wear longer and resist burning
- 15% stronger heavy duty, shot peened clutch springs to clamp those plates together firm and strong for the life of your clutch
From Barnett, the number one name in motorcycle clutches since 1948, we now offer a complete high performance clutch set. This includes Kevlar friction plates, steel drive plates and stronger springs.
Barnett high performance clutch kit includes drive plates, carbon fiber friction plates, and heavy duty springs.
The EXP disk is the magic ingredient behind the functionality and benefits of Rekluse auto clutches. About 10 years ago, Rekluse introduced an innovatively redesigned version of its revolutionary auto clutch technology with EXP 3.0. The years of racing, testing and development since have led to Rekluse’s most refined auto clutch experience yet; Introducing EXP 4.0.
No More Stalling:
Using principles of centrifugal force, EXP technology automatically engages and disengages the clutch based on engine RPM. With EXP, riders can start and stop without touching the clutch lever. EXP automatic clutch technology provides riders precision throttle control, maximum traction and confidence to maneuver any obstacle on the track, trail, or road.
Less Arm Fatigue:
You don’t have to clutch as often, which preserves your arm for longer rides.
Tunable to Fit Your Riding Style:
Each auto clutch is optimized for each bike model as it comes from the factory, and EXP 4.0 has been developed and tested in a wide range of late-model motorcycles. However, everybody rides differently, so they made sure EXP technology can be fine tuned. They offer different spring and wedge options so riders can further adjust their clutch’s performance. Some riders like the clutch to engage just above idle, while others like later engagement.
Clutch Lever Is Still Functional At All Times:
It is possible to fully override the auto functionality at any time. You can pull the lever in, build RPMs, pop the clutch out and raise the front tire just like normal.
Have More Fun:
You don’t have to worry about covering your clutch to prevent stalls all the time. You are free to relax and enjoy the ride, having one less thing to think about.
This kit includes one OEM drive plate retaining wire & one OEM inner steel drive plate.
If you've ever changed the clutch on a DR650 you will be familiar with the extra steel plate at the bottom of the stack that is locked in place by a very thin metal wire.
Generally, when you do a clutch replacement on the DR650, you do not need to remove or replace these items. If you do need to (or if you have already) you will come to realize this wire is not very strong and is prone to breaking if not treated with care during the removal / installation process.
RadiusX is a high performance centrifugal auto clutch combining our TorqDrive and EXP technologies. TorqDrive provides more clutch disks in less space, allowing for maximum performance within your bike’s existing clutch footprint. You retain full control of shifting and use of your clutch lever with no compromise in power delivery.
Features:
- Dead-on clutch engagement every time
- Take off and stop in gear without using clutch lever – no more stalls
- Experience maximum power delivery
- Confidently navigate traffic and slow speed conditions
- TorqDrive® clutch pack delivers higher torque capacity and increased power transfer
- Rekluse sleeves eliminate basket wear and notching
- Standard clutch lever function with full override
- No modification to stock components
- Shifting transmission remains unchanged (clutch lever use is recommended for shifting)
Complete set of friction plates, HD springs and steel separator plates prevent premature driven plate wear, oil muddying and loss of stack height. Built with swaged aluminum carriers that spread the load on the clutch basket and prevent clutch basket "dogging". Anti-swell, alloy impregnated heavy-duty cork-based facings for smooth clutch take-up. Allows modulation, unlike paper clutches which tend to snatch.
The Rekluse EXP employs the same EXP assembly as their premier product; the difference is that it fits into your stock clutch assembly, saving you money! Now you can enjoy the benefits of Rekluse auto-clutch technology on your KLR.
An auto-clutch automatically feeds out the engagement of the clutch using centrifugal force. This allows you to start and stop without touching the clutch lever. The automatic feed is fully adjustable to suit the rider's needs while retaining full manual override with the clutch lever. This automatic feed delivers easier on/off throttle transitions, improved traction, better control, and more confidence.
Since 1948, Barnett clutch plates and springs have been made from the finest materials available.
- 6 Kevlar friction plates
- 5 Steel drive plates
- Clutch springs
- Clutch cover gasket

Here's another item you might want to replace when you are changing out your front sprocket. Because of it's big back tire, the chain is further away from the center of the engine than most bikes. The engineers at Yamaha decided they had better support the end of the countershaft since it is cantilevered out there so far. They also figured they had better feed some oil out there as well. These Countershaft Seals keep that oil where it belongs, lubricating the countershaft outer support.

Our very own version of the popular thermostat bypass for the KLR. Gives faster warm up and more constant engine temperatures. Eliminates the wildly fluctuating engine temperature gauge. A more controlled and constant temperature is easier on your piston and cylinder and may prevent or reduce oil consumption. We use a 180 degree thermostat instead of the stock (too cold!) 160 degree unit. Warmer coolant temperature promotes better fuel vaporization and can increase fuel economy.
Our bypass system mounts the new thermostat in a small billet extension housing right where the stock thermostat is now. There is no bulky external housing to hang off the motor. The bypass hose tees in to the lower radiator hose using a length of quality high temperature silicone hose. It all makes for a clean simple installation.
