Check your swingarms to avoid this... and sell me your spare!

[2001-400ex'er]

Went riding some MX yesterday and was checking over my 400 when I noticed this.. It cracked the entire way around. So make sure you check yours for cracks if you ride it hard before it breaks off and rips the back half of your quad off. Oh yeah, I'm looking for a stock or aftermarket stock length swingarm if anyone has one laying around, thanks! PM me or text (920) 960-3759

I think this is a known issue. If not, then it should be. I am currently on my 4th OEM swingarm. Each one has failed in the same exact place as yours.

Wow, guess an aftermarket one would be worth the money then if it's just going to happen again

yep i destroyed mine but from not changing swingarm bearings untill they were gone lol. Aftermarket is the way to go the price hurts though but try not to think about it lol

I've busted a Houser and a Lonestar too (not on my EX, but a Honda 450R). The OEM swingarm is stronger than the aftermarket companies would have you believe.
