I brought my szr blue on august 4th 2011. Before first service I used to get mileage around 40 kmpl. After first service and just prior to second service, mileage was around 46-47kmpl. After second service, seems like bikes power got reduced a bit. but not much. now mileage is around 48 kmpl and bike has crossed 7500 kms.:) It is stylish, comfortable and having good handling. The bike has tachometer. which helps a newbie to shift the gear at correct rpm.:) .
The drawbacks am seeing in this bike is, no kick start (at time of purchase) can add it by paying around 2000 rs I added it on my 4th free service, also the gear pedal is old type. Not like fz no park light and pass light in this bike. and the speedometer is not digital but as far as am getting descent mileage of around 48 -50 kmpl in mixed condition, and good handling n also style compared to other 150 cc bikes. I am happy with my decision of purchasing this bike.
