If youre used to riding dirt bikes, yes, its a tank. But IMO, for its size and weight, the B12 feels pretty light and agile. Not excessively topheavy, even with a full tank of go juice. Granted, Ive never ridden a true sport bike, the only other sport-ish bike Ive ridden is my roommate's 750 katana. My first street bike was a 79 GS750. Even with a 3.3 gal tank, it was heavy. Its just a pig. But after a few thorough parking lot practice sessions I learned to manage the weight. The first time I rode my B12 it felt like my old YZ250 compared to the GS.
