Ok, I have been trying to fit ODI grips to my 18 500rr-s for over a year. I was told Cam E for a KTM 65 fits, and it sort of does. The Cam E is the same shape, but the profile (think mohawak) is not as long (think mohawk does not go all the way to the front of your head). I have ran the bike with teh cam installed for a bit, but it was too sloppy for my liking. I am thinking I can adjust my throttle cable to remove the slack.
I have a set of A'ME heated grips and A'ME fits perfectly. I had them send me the beat CAM as they do not include it since Beta's are rare. Anyway, I have confirmed Cam D fits the 2t, but cam E comes up a little sloppy for the 4t.
Anyone have luck with a better fitting CAM? I have a call into ODI and waiting to hear back.
