I have decided to replace factory tires on my 2008 Kawasaki Vulcan 900 LT at only 6,500 miles. The tires still had a plenty of life, especially the front one, but I felt instability when riding over pavement grooves. I purchased 130/90H16 67H front and 200/70HB15 82H rear tire combo. The larger rear tire (compared to factory size) represents a Stage 1 upgrade (see the Metzeler website) for VN900 and adds about $110 compared to the standard-size combo, but is worth every penny. The delivery by MotoSport was without a glitch. The larger and wider rear tire looks great and fills the rear fender much better than the factory tire. There is no clearance problem, no modification to the bike is needed with this upgrade. Better yet, the speedo is now much more accurate and I am no longer chasing between 4th and 5th gears in city riding or grabbing for the non-existing 6th gear on a highway. From what I have read, it is almost like having a custom larger front pulley installed. But, do NOT install the larger rear tire if you did upgrade the front pulley on your VN900. That would apparently cause clearance issues with the original belt and splash shield. The bike felt different (that is, much better) right after installation of the Metzeler combo. I now have close to 2,000 miles on the Metzelers and the ride is smooth, stable, and secure. There is no noticeable wear so far.
