This is a good buy. I bought the bike in AUgust-05 and have already drove more than 8, 000 kms. You get the best of it in highways. The best part when driving at higher speeds is...you can feel that the tyres have a good road grip. I am getting a mileage of 55kml and that is the max you can get (as told by the servicing dealer..)
I have always used Indian Oil extra premium petrol...but yes there are no reasons to believe that the mileage I am getting is due to the petrol.....may be it is somewhat due to this petrol....
One strange problem I faced was in the headlight. It was gone after 6months and the dealer told me that it was the problem of RRUnit (no idea what it is...). But yeah.....I was not asked to pay any money and was told that it would be replaced as the thing is under guarantee....
All in all, the bike is excellent in highway conditions and ok in city conditions.
