I know this question has to have been beaten to death more times than Hillary has lied to the public but I'm facing a decision that I'd appreciate some input as I'm VERY new to the motorcycle world. I bout a 09 klr 650 with 24k miles on it probably bout a month ago from the dealer and I noticed the rear tire tread is getting a little low on the tread line. Therefore I'm looking to buy a backup tire for when I'll need to change it. I ride mostly on roads but a decent amount on gravel and dirt roads as well. nothing extreme. I'm trying to decide between the Heidenau K60 or the Mefo Explorer. Lets hear some of your thoughts on these from those that have them. I'd like whichever is higher mileage since I ride my bike mostly to avoid driving the jeep that gets 11mpg (Damn suspension lift and larger tires). Lets hear your thoughts.
