Hey guys, the title says it all. Above say, roughly 50 mph or so, on any hard surface (road, dry field) I get a terrible headshake. This isn't normal on a 1st gen 450f, right? On a soft surface, it wont do it. I find it pretty annoying that some of the guys I ride with, on CRF230's, will blow by me going through a long straight away if it hasn't rained in the past week. Any other suspension tidbits you guys might wanna add would be wonderful. I admit, I know nothing about it. My bike's suspension was 'set up' for a guy just about my height and weight (thankfully), but that was for motocross. It has a little sticker with some of the settings on it.
