I recently installed the BPX360 balancers on my Husqvarna TE 300i. I figured it would help out with the shake at top speed. But this product greatly exceeded my expectations. It not only helped with the shake, it increased my top speed and acceleration. It has helped every aspect of my riding, hill climbs, rocks, desert, motocross and fire roads. Makes my bike feel so much smoother. I am going to highly recommend this product to all of my friends, and I encourage everyone to put this on their bike.
