I think it breaks down along the fingernail line. If you're afraid to get dirt under your fingernails and want a dealer to lube your chain, BMW. If you want a project you can enjoy all year around, KLR. If you want something with incredible off-road prowess, XLR or KLX. If you're hell bent on spending money for no obvious reason, Yamaha. If I were going to rack-up a ton of miles on the interstate every year? Well, I ride 5 miles of gravel and 34 miles of interstate every day I ride, I ride down to 36 F (normally, if it's dry). If the bike gets a scratch in the plastic I don't care, if the plastics get broken they're relatively cheap. If the tank gets trashed I'm going desert camo or Air Force ABU digital camo rattle can commando. I bought my KLR with the intent of riding it to death, and that's exactly what I plan to do.
"My KLR belongs to God, when he wants it clean he washes it."
