I have a few
1. After rebuilding a very sorry Lambretta from the ground up, starting it and hearing it run for the first time. that was pretty special.
2. Passing my test
3. Riding my Ducati for the first time. what a RUSH.
4. Leading a scooter ride of about 60 bikes through Arches National Park in Utah earlier this year.
Sorry theres not more motorbike related ones, but im still in my first year of riding.
