I've liked all the bikes i've owned so i wont say a best and worst lets say least favorite: 1981 Suzuki GS 450 L reliable but way underpowered.
Most favorite (not counting present bike): 1984 Honda Night Hawk 650.
The percentage you're paying is too high-priced
While you're living beyond all your means
And the man in the suit has just bought a new car
From the profit he's made on your dreams
