My 2007 America came with 110 / 90 Metzelers. The front tire was shot at 6,000 miles. I was told by the parts guys at Gengras Motorcycles that the OEM tires were not the same as the same tire purchased as a replacement. They said the tire makers cheapen the tires to meet OEM price points. I had never heard of this before, but it sort of makes sense. I ended up putting on a Metzeler 100 / 90 because they were out of the 110 / 90. Initialy I noticed the smaller width tire made the handling more sensitive to the point that I wasn't sure I made the right decision. After riding it for a few weeks, I got used to it and it feels fine.
