I'm using Bajaj Discover 150 since 2014, near about 100000 km I have rode it. Only issue I think is fuel leakage. I rode it 450 km in a single day, with no issues.
I rod this Bike 110 kms in a day without facing problem. Rich 80 kmph speed with weight of 120 KGS with slide throttle. Mileage is good too in this segment. Now I want to ride with pillion rider on hills. I love this bike Discover 150 old 2011 model. It has its own problems too. That is leakage of engine oil. Other wise good.
Best Features: I rod this bike 110 kms in a day not feeling any problems. Great pick up. With me, my wife and 1.6 year old son accumulated weight of 125 kgs got 80 kmph.
Pros: Using since last 7 years. Feeling problem not so much. I rod it 110 kms in a day not feel so much problems with it. Up ride position is nice enough and good for long ride.
Cons: Nothing so much.
