I bought my Pulsar 150cc on 27 Feb-13, till date I feel worth for my money. I had been through all reviews over here before I choose. Every one shared their own experience that we should value. I had a ride in my Pulsar over 12000 kms till date, its awesome feel when I ride long drive. When u compromise with ur speed 50-60 km/hr then u definitely get mileage around 55-60 km/lt.
I used to ride my bike 90-100 km/hr still I got a mileage around 45+.
If ur planning of Yamaha FZ, surely u can go for Pulsar 150cc. Its worth for ur money.
