Had a good friend that rode an XB12r for 5 years and spend a lot of time in the saddle of that bike. It was incredibly fun to ride for about 1/2 hour at a time, and then it got old. The bike will vibrate itself apart, most exhausts on them are stupidly loud, and that bike spent more time broken than not.
Most notably the rear exhaust pipe stud would continually shear off inside the head on the rear cylinder, and it can't be extracted on the bike. Time to pull the head off!
