Sorry to hear that - yes they certainly are dangerous - I started racing off road when I was 17 and developed a lot of riding skills, but I never felt comfortable riding them on the road. I did ride a bicycle every day though and had a few crashes doing that.
NZ used to have a big motorbike scene, but now there are very few, and over 3x as many cars as there were 30 years ago. When I was a baby my parents put a sidecar on their Triumph Tiger 650...
