My Bandit is living proof that the bandit engine is bullet proof. My 600 has 80,000km on the clock and has never missed a beat. The bike is 12 years old, and still as good as any new 600 in the same class. I have owned the bike for 2 years and all I can say is if you are in the market for a 600cc bike you will not go wrong with a Bandit. I love the naked look of the bike, and it is just a really usable tool.
