Do you really equate race bikes to street bikes?
Just a couple of comments:
This was a first run for this bike, the proverbial shake down to see what's going to fail in a racing situation.
These bikes are a "race only" version of the streetbikes. The problems were basically clutch problems, and they are being addressed.
Remember that this is basically a "real world" street bike that handles so well that it should be raced. It was never designed to be a 200mph crotch rocket, so there's bound to be some shakedown issues.
As for their street bikes, myself an many other XB owners will probably tell you that problems are negligible, maintenance costs are low, and the fun factor is extremeley high.
On track days it's interesting to see how well they handle as the Ducati's (air cooled) are slightly faster in the straights, but they Buells are jammed up behind them in the corners.
I ride 50k to the track, do 8 hours of track days and ride it home! No drama, no problems. Only issue is that the fuel tank is so small I have to fuel up during the day.
Buells have their quirks, but once you start rolling on the power and you fell that torque (xb12) it's a hoot.
I look at it this way, I get 4000k out of a rear tire, and it's worth it. I ***** when I don't get 12000km out of the tire on my road king.
