Hi, I too have surpassed the 16,000km mark with my 2008 B&W150 and couldn't be happier. Aside from the styling, this scooter has proven absolutely worthy. The cooling system works extremely well and only once has the fan came on, but even then I was fully loaded with camping gear, a 1/8 scale RC car and accessories, box of wine, some tools, food for three days and my wife on the back, while riding through wet sand for about 5km in 30 degree C weather (86F). Belt went at 12,000km, I now carry a spare and seriously advocate others do the same. It isn't as good on fuel as I initially hoped, but compared to driving my Jeep Grand Cherokee, it is a blessing. Brakes are strong enough, although I do notice on really hard braking that the whole front of the scooter levers forward just slightly; brakes stronger than the frame?
Also, it should be noted that I am absolutely aggressive with my scooter all of the time. I really try not to, and even feel guilty sometimes at the end of the day when I put it in the garage, but I ride wide open or full brake and very little in between. I also ride a lot of intermediately aggressive off-road trails with lots of rocks, roots and water crossings. This little 150 takes it in stride and has never once had any kind of minor or major malfunction, hiccup, miss, lag, lack of power or anything. It always starts instantly, never smokes, stays clean and runs like new.
My last bikes were a GSX-R1100 and street legal XR650R, both considered fairly wild mounts, but nothing really comes close to the fun and silliness that happens while riding a scooter. Even if when in a un-official race across town situation, chances are the scooter wins, but the victory typically goes unrecognised because it is just so funny.
I love this scooter and am presently outfitting it for a trans-Canada run this spring.
