I have used my friends pulsar 150 dtsi a more than 500 kms and it has some of the cons as follows:
1. The bike starts very quickly and is having good engine that never stops on using it continously for 4-5 hours also.
2. When the speed reaches above 60km/hr bike makes very much sound is very inconvenient for a person driving for long time at such speed to cover a long distance.
3. For steep slopes, muddy areas the bike had superior faceoffs with the roads yet worked perfectly smooth.
4. Bike needs servicing after every 500- 600 Kms of use to function properly and work perfectly fine.
5. In terms of the style and appearance I love the finishing and the seat adjustments. If you are more than one person on a bike it is perfectly comfortable.
