What exactly goes on at HighPipe Motorcycle Festival? It’s a fair question, especially given it was the first event of its kind. HighPipe is a celebration of the go-anywhere, do-anything motorcycles—a throwback to the golden days of motorcycling. With the resurgence of these classic steeds (and skinny jeans, mustache wax, flannel shirts, trucker caps, etc. ), it was high time for an event like HighPipe, a tribute to classic motorcycling.
