My last bike was a KLR650, actually it became my last bike when I pulled it out of storage after two years one morning when my Beemer crapped out yet again. Drained the oil, dropped in a battery and it fired right up like it had just been ridden the day before.
GREAT bike, right out of the box. I pulled some 1,000 mile Interstate days on mine, flogged it off road and on, and in a corner the first thing that woulda touched down was the handlebars Dead-nuts reliable too.
I will add another perfect motorcycle requirement though.....
8) TUBELESS TIRES
Even today spoked wheels almost always mean inner tubes, an absolute PITA when you get a flat. On a tubeless setup a rubber rivet and a can of fix-a-flat will usually get you home. On a tube tire that tires gotta come off.
