I think a passion for airplanes and motorcycles go hand in hand. Right now I have a 1988 Honda Hawk GT650 (best bike ever made for real world use) and a 2002 Honda CR125, and a 1979 Yamaha GT80 I bought new in 1980!

Progression of bikes:

1979 Yamaha GT80
1972 Honda CB360
1983 Yamaha XS650 Heritage Special
1989 Suzuki Katana 600

I went about 10 years without a bike after my son was born, but now I have determined I will always have a bike! Owning a motorcycle is a lot cheaper than owning a plane, and gives it me the same enjoyment as flying. A poor man airplane!
