Sad to say but I am garaging mine until the rear sprocket can be replaced with the newer version. The noise of it is drowning out the tailpipe burps and one of the guys at the local filling station commented to me about it after I coasted in and it was still noisy!

What's your mileage? Who cares. Is it practical? See #1. What happens when it rains? You get wet.
