My '06 came with Bridgestone Trail Wing 301 (front) and 52 (rear) dual purpose tires. They seem to work fairly well on the street - a little loose in the dirt. I'm looking to keep the bike street-able but want something that's with a little more hook-up in the dirt. I prefer not to go with full on knobbies and would like to replace what I've got with some type of dual purpose tires. What do you run on your XRL? Has anyone tried the Dunlop 606 and what's your opinion? What about the 907 or the new 908RR?
