I bought Suzuki Gixxer around 1 month back and till know ridden more than 750 kms, so I am in a good shape of writing a one month riding experience of my bike.
Before that I must say that I was searching for a bike for my budget for the last 6 months and the bikes which I was considering was Honda Hornet 160, Suzuki Gixxer 155 and Bajaj Pulsar 160 NS, thus I settled for Suzuki Gixxer after reading quite a good reviews of it. Along with the power the design of it is totally awesome.
The handling of the bike is too good even though the riding position is slightly tipped-forward. Along with handling one think I must say that it is fuel efficient too with giving me around 50kmpl easily.
As of now the only problem I have faced is that the Bike's back Brake is not that great. You have to apply front brake everytime if you need to stop immediately. Pillion rider will have some discomfort as the pillion seat is narrower.
