For a new Mother Clutcher aftermarket primary clutch made as a OE style Kawasaki primary (aka drive) Brute Force 650 and Prairie 650 & 700 clutch. They have also been updated some.
There is more details on that down below after the fitment. This clutch comes pre tuned specific for models above. This comes correct for ready to bolt on and ride with weights and spring already in it!
Upgrades made are that the clutch has the wider weight slots and wider weights in it that Kawasaki only using on some of the 2008 and newer models. I wanted to use the newer wider weights design, but with the grams of them to keep the clutch in the peak rpm range. The weights that come in this keep the rpms at full throttle applications in the peak power band for the 650-700 stock v-twin engines which is a peak HP RPM of 6500 rpms. The low and mid throttle range acts like a new oem stock clutch. Another update made is the spring.The oem springs on these models are a very short spring that barely put pressure on the metal cover when not under a load which made the oem clutches often compress down on the the CVT belt slightly at idle so they wouldn't always 100% disengage which can make it slightly sticky/grabby when trying to shift. For that reason this comes with a slightly longer spring in it for smoother gear shifting.
