I got this for my son on his CRF150R. He just moved up to this bike and had trouble with the stock clutch pull - couldn't finish a 90 min hare scramble. He absolutely loved it, use the clutch lever to feather it for more power if needed, or just downshift and twist the throttle. No more clutch arm fatigue at all. IMPORTANT NOTE: if installing on crf150r, make sure you include the needle bearing and stock washer on the throwout rod, then the Rekluse spacer washer and spring. The directions weren't clear on that - the rest of the install was a breeze.
