I bought my Pulsar in August 2009 and already completed 20000 KMs.I am not a technical person so I will write the exact things I felt after these 20000 KMs of bike riding.
Lets start with the positives:-
1.No engine problems at all.I havent faced a single problem in two years.Yes, I did all the servicing on time & didnt try any stunts.
2.The power.The bike still catches the same pick-up and shows its power just like 2 years ago.
3.Handling & Gear shifting is still very comfortable.
Negative:-
Mileage.In first few months it was giving me 50KMPL.Now it dropped to 40-42 KMPL.
So guys If you really want a tension free bike then go for Pulsar 150.Actually my first choice was Apache and Honda stunner but After I got negative feedbacks from apache owners(not on mouth-shut) I decided to buy Pulsar.I rejected Honda stunner after I took the test ride.
