Heavy duty clutch springs by Barnett are included it this kit which will significantly decrease wear under high stress conditions.

• Complete set of friction plates, steel plates, and springs
• Heavy-duty springs help prevent clutch slip
• Restores proper stack height, fixes clutch slip caused by wear and tear

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.

Hinson Clutch Plates available as a set of just Fiber Plates or just Steel Plates or as a complete set including both.

Hinson Clutch Components sells the best clutch components available in the world. Hinson equipped machines have won 224 National and World Championships in our 20 years of business.

• Optimum hook up with minimum heat build up provides high performance
• Developed with and recommended to enhance the performance of Hinson clutch baskets, inner hubs, and pressure plates
• Exceptional production tolerances and flatness
• All fiber plates use organic non-abrasive materials to avoid damage to rest of motor as plate materials break down and are circulated through engine by oil
• Can be used with OEM baskets, inner hubs, and pressure plate

Barnett high performance clutch kit includes drive plates, carbon fiber friction plates, and heavy duty springs.

Replace your worn clutch plates and springs to reduce fade and slip.

• Complete set of friction plates, steel plates, and springs
• Heavy-duty springs help prevent clutch slip
• Restores proper stack height, fixes clutch slip caused by wear and tear

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, and allows engagement modulation, unlike paper clutches which tend to snatch.

This is an extended version of the stock DR650 clutch release arm that is manufactured by Suzuki.

Upgrading to a longer clutch release arm will lighten the pull of the clutch lever through means of increased leverage. This means less fatigue, quicker clutch engagement, easier clutch modulation and longer rides.

The extended clutch arm will not offer a drastic change in clutch pull. If you're looking for a major change in clutch pull at the lever, we recommend getting a Magura hydraulic clutch kit.

In this kit you will get 4 factory replacement bolts to replace any broken or damaged clutch pressure plate bolts on your DR650.

It can be easy to over torque these bolts if not done properly. If one of these bolts is damaged on your DR650, we highly recommend replacing all 4 to prevent any future failures down the trail.

Since 1948, Barnett clutch plates and springs have been made from the finest materials available.

The EBC DRC kit is the best way to reset your bike’s clutch to the exact as new standard sizing. Replacing just the plates can work but new clutch springs are always better and springs get tired and can cause slippage plus the separator steel plates from EBC are pin-planished, forming tiny indents in the steel which improves the spread of oil around the clutch surfaces.

Includes:

• Friction plates with EBC unique alloy article impregnated clutch facings that wear longer and resists burning.

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.

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.

• Rekluse sleeves eliminate basket wear and notching
• Proven in racing at the highest levels
• Made in the U.S.A.

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.
