Yup, you read that right. In the 5 years I've been riding I have logged over 80k miles seat time. I feel that seat time trumps years riding any day. For seasonal riders, depending on climate, you're lucky to get 2-3kmiles a year. I ride year round, with exceptions made for snow and ice, averaging 15k per year commuting, and several thousands on road trips. And that's why I'm upgrading to a Victory.
I started teaching to help new riders to stay safe. The majority of accidents in new riders occurs in slow maneuvering and failing to negotiate corners (target fixation). Much of what we teach is super beginner stuff IE; friction zone, shifting, obstacle avoidance, emergency stopping, etc, etc. You don't need to be a life long rider to teach this, you need to be passionate about motorcycling.
