Not Satisfied with Mileage

Its been 2 years, I am riding this motorcycle. The changes I noticed in this bike in these two years is its mileage. I used to get an average of 57 kmpl on heavy traffic and now it dropped down to 47-49 kmpl only. It seems that its engine is rated to deliver good mileage only for 2 year. Positive aspects of the bike are its comfortable seat and pillion. Its looks are average and handling is also good but the main mileage department is bit annoying.

Best Features: Nothing

Pros: Riding comfort, Handling

Cons: Mileage, Looks
