No, I have not had an accident. I accidentally ended up with an MP3 400. I rented a GTS 250, my normal ride, from Eagle Rider in LA for Amerivespa but ended up with a choice between an LX50 or the MP3. It has definitely been an experience, especially considering that I am a small/short woman. I reach OK but don't really have the height or weight to maneuver it at low speeds properly.
I rode it from LA to San Diego and then on the mountain ride today. I'm still not used to it, especially how much further you have to lean than a PTW. Unfortunately, being a rental, this bike is probably not a good example. It seems to really lug at low speeds but maintains good speed and acceleration at higher speeds. It's definitely a lot heavier and requires much more attention to braking. I don't dislike it, but learning to ride one in unfamiliar territory with a lot of unknown riders around us a bit disconcerting.
Any advice? I have been avoiding the tilt lock, except when parking or maybe stopped on tilted surfaces. It seems like it should have a reverse:)
