i do. i have two bikes - my favourite is my 1979 kawasaki kz 650 for everyday city driving. light bike, nice acceleration, 65 miles per gallon. this is the most comfortable bike ever developed - you sit upright and comfortable. i love it.
my other bike is a 2006 bmw k1200. it is delicious, but too heavy for everyday city riding.
a bike is cheap, friend! cheap to maintain, cheap to insure. your wife will love the math!
