The B12 is 30,000km and 4 yrs old, and other than the nasty stuff I've done to it - like falling off, it hasn't missed a beat. 30,000km is not much, but it gets ridden just about every day to and from work which is only a 12km round trip - not good for a big bike - but the B12 just keeps on keeping on.
Now, I may be a bit biased (owned nothing but Suzuki's), but if I HAD to buy another bike, I'd buy another B12.
