I was doing laps at the MX track when my RPM steering stem broke completely through at the upper weld. It looked like the thickness of the stem wall was not equal all the way around. Calliper measurements confirmed this. I was also surprised how badly the rubber O rings in the bushings had worn grooves into the stem. I thought this chromoly steering stem was supposed to be stronger than stock.
I also had to grind a handle bar mount because that was not machined correctly.
I do like the anti-vibe setup it has.
Anyone else have one break?

 

I had alot of problems with their bearing carrier fitting in my 400ex it was not machined properly I had a local shop fix it wasnt even close to being right
