Title: The dredded KX500 subframe
Post by: Ramski on March 27, 2004, 04:54:13 PM: Well, I'll be replacing my third subframe here. The last two were AC Racing aluminum units. The fit great but don't fare well when looped. There is a guy here in SoCal that makes nice steel ones for the Team Green guys that are much stronger and under $200. (OEM is $400 :shock: ). As soon as I get my hands on one of these I'll post it.

Post by: Rick on March 30, 2004, 02:25:30 AM: So, where exactly is everyone bending their subframe? I have never bent a subframe, and only cracked one on the top over the airbox.

The first aluminum subframe I had got bent up and to the right (looking from rear) and cracked around the pipe loop. The second, I'm not sure yet as I havn't seen it. I rode it, bent it and gave it to my brother to store while I went to Korea and he said he'd take the bike apart while I was gone and let me rebuild it when I get back. This weekend I start the rebuild and I'll see how bad and where it bent.

(And as Rick knows...)

Team Green re-welds the stock part and adds a piece of steel (via two to four rivettes) where the chain rubs.

Been there...
Done that...
Have bent sub's due to some interesting get-offs...

Post by: 99KX500twofast on April 16, 2004, 04:03:41 PM: OH YES, this last 4th of july I bent mine on the left side where it supports the fender, was able to bend it back into line and it works fine. However i was delayed in starting the repairs due to the little get off causing me to have to get 2 screws in my kneecap and a new acl in left knee. Had a heck of a time getting the K5 started so I could ride back to the house. I'm doing ok and the 99K5 is still awesome.
