I own a 2004 model, till now no major issues but changed few things till now clutch plate, battery, tyre and headlamps. I have crossed 50K and my daily usage is high.
One thing I like is that it is a reliable vehicle, Mileage various depends upon your driving style. I used to touch 80 KMPH once in a day. I am getting mileage of 50 only.
But till now, it never put me down, I like this bike.
