It's like everything else in life... if it was put together something will go wrong sooner or later. Mistakes happen.
My 04 Daytona spun a crank bearing in just 4800 miles in the middle of the summer and the dealership was so busy I didn't get the bike back for two months. On the plus side the warany covered it all and I got a engine.
i have spent a year whinging about brakes and still no real joy then just on the off chance at the year service i mention that the footpegs have lost their shiney look and within 3 days they phone me and say theyll replace them under warranty.
now if only they would replace the calipers for me (with some brembos) ;D
