My one piece clamps turned into 3 piece after going over the bars in the whoops section yesterday, happened on lap one of a 15 min + 1 lap race, and I finished the race and got back up to my best finish of the day! But the bars were held with the left side of the clamp only, the right side has split where it clamps the bar, could have ended much worse than it did, all i did was chomp on my tounge really hard when I landed on my head. Bike is a 2011 rm250

As much as I love Suzuki RM's & owning 3 of my own in the past I've never seen a bar clamp break like that? It must have been a really hard landing to break like that! I would take the clamp to the shop you bought the bike @ and show them & see if they could possibly replace the clamp. :)

Fast whoops/rythem section, 7 in the set, i tried to go triple triple single, but cased the second triple, the front dropped into the dip really heavy and went straight over the bars, the bike landed on the bars on the upslope of the last one, i know why it broke, its because the clamps are rubber mounted on the upper triple, so they tried to move more but the solid square piece clamping the bars wouldnt let them, ive ordered some different clamps that have 2 separate bar clamps, rather than one, if any of that makes sense lol

I almost purchased a pair of rubber mounted upper clamps when I had my "08" ktm 300xc but went ahead & spent a little extra $$$ on a set of fasst flex bars which I love for the places I ride on the Eastern U.S. Mostly tight woods & GNCC style riding. Those bars are a bit on the heavy side for MX though imo.. :)

The rm came standard with rubber mounted bar clamps, on my kx85 I had a few years back the bar clamps were all part of the casting of the upper triple, and after a big crash I got back on with what I thought were bent bars, but later discovered the bars were straight and the steering stem was out of shape, that was with renthal 7/8 bars, so a set of £30 bars cost me £200 in a set of new yokes, I always trust everything from renthal now, there stuff is often stronger than the bike its bolted to ;D
