The sport bike motors are as well.
I put 56K on my ZX9R in 4 years, still had the original clutch when I stupidly sold it, and I drove it like I stole it....
Consumer Reports finally came out with a motorcycle reliability list. How often the bike brand has a major issue.
Yamaha was #1....
Now get this. Kawasaki was #2 with Honda being #3. It changed my perception of Kawasaki.
Last on the list was BMW with the worse reliability.
