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.

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.
Since 1948, Barnett clutch plates and springs have been made from the finest materials available.
Heavy duty springs help prevent clutch slip in high-performance motors.

The tool contains a pair of pliers, a rasp, an insertion tool and a sharp knife, which is all you'll need to fix 99% of punctures. The repair strings are pre-vulcanized, so they've done away with the "little tube of glue". The repair plugs the hole AND leaves a "patch style" repair on the INSIDE of your tire.
