I bought my first Kawasaki in 1973.
For bikes my favorite is my newest, a 2008 Kawasaki ZZR600- my 70s and 80s bikes were less reliable, vibrated more and had weaker power, braking, shifting and handling. The air cooling made me sweat more in the summer.
I still own a 2002 Honda Shadow 600cc cruiser, with the old style V-twin, 4-speeds, but newer water cooling, and about half the vibration of my previous 1978 Yamaha XS650.
For the dozens of bikes you have owned or ridden, which few stand out the most?
“We need randomness, mess, adventures, uncertainty, self-discovery, near-traumatic episodes, all those things that make life worth living; compared to the structured, fake, and ineffective life of an empty-suit corporate leader with a preset schedule.” From Dr Nassim Nicholas Taleb, Antifragile: Things That Gain from Disorder
