Chanfge out that POS stock exhaust and you will see a huge decrease in the wear pattern. What were they thinking? 50 extra pounds on one side of the bike?

By having all that extra weight on the right side, you have to "lean" the bike towards the left side to balance that exhaust weight on the right. Thats why the left side wears more, you have it leaned slightly to the left to compensate for the exhaust weight. This is also the reason that, to keep your bike tracking straight down the road if you are riding no-hands with the throttle locked, you have to shift your weight to the left, to better balance the bike., If you are riding straight ahead without hands, the bike wants to track right. You can either shift your body mass to the left or countersteer by pushing on the right side of the bar, which rides the tire more onto the left side. That is what really does it. Try carrying about 40 extra pounds in the left saddlebag... when you let go of the bars with your throttle locked, your bike will track straight, without needing to countersteerwhich would put more weight/angle on the left side.
I'm not saying that the left turn theory is totally invalid and does not account for some of the wear...I believe it adds up to a little of the increased wear, as does the crown theory. But since I do know how much countersteering effort is required to "right" the bike to go straight because of the added right side weight, and since that throws the tire into a left angle, making the bike ride on the left side, I believe this is the primary reason.
