I love mine. On the 07 EC300 with the Marz 45's the fork never hit the unabiker guards, but I just finished the "fork swap" to KYB SSS (48's off an 06 YZ450F), and they hit the top of the unabiker's, so I just notched the top of the front screen. Actually the bolts on the TC hit, not the fork itself...But like I said, they are a perfect fit for the stock setup. And yes, they are tough... I know because my bike spends more time on it's side than upright.
