t1000 miles on my bmw c 650 gt - very nice scoot. I have noticed no vibrations and acceleration is smooth. Only a few complaints: rear view mirrors are placed a too far forward & dash lcd is monochrome and is difficult to see in daytime with the shades on. Noise is a little high but many like it that way. Horn is pathetic! Too much tupperware but cars now have this problem too. Extra passenger is no problem - barely notice. Heavy maxi - gone are the days of wearing dress shoes for intraday errands. As i live on the coast it is nice to see no corrosion so far.
