You do want the swingarm to be centered. But on a properly setup bike, the rear tire will not track exactly along the line of the front tire. It's just the design of the bike. BMW did this to offset the rotation affects of the crankshaft along with the coriolis effect when riding in the northern hemisphere to the west of the meridian line. What for it......jjwithers wrote:However, Are you saying that a /7 and up has a front and rear tire that is not lined up? That seems very un-BMW.
And, I thought un-centering a swingarm between the frame was a big no-no. I know it can be done... but that would be wrong.
Swingarm centered, use the spacer or not depending on the size of the tire...the bike should run fine. If it doesn't then you have much bigger problems than this.
