I must tell everyone how much I have enjoyed myself on the 400. After moving up from the now tiny 49cc Yamaha jog, my wife and I faced this enormous 450# scooter, an enormous challenge, such a different experience. In the beginning, it felt a bit hard to control, especially on turning the corners from a stop. Now 750km later, I fell totally comfortable riding it, and find it much more than my other scooter. Much more of everything (all positive). I take it to work when the weather allows it. The break in period sometimes cramps me, when I just want to feel the speed. A few times it just zoomed up to 120 kph before I regretfully slowed it down. I love pulling up to a light beside some snot nosed kid in his fast RED car. The light changes, and I am suddenly gone, practically before his wheels start to roll. I like being a bit higher in the saddle then I was with the old bike. Still have not had an opportunity to take it on the highway or on any longer trips, due to this breakin period, but hopefully I can finish the 1000 km this summer before the bad weather arrives. Anyway, I love the machine, and I thank my friend Harold who bought the 650 and suggested that I look at this bike instead of the VINO 125 that I had originally wanted to buy.
