I bought TVS Streak in April 2010 from Kubera Motor in Bangalore. Till today(15 months from the date of purchase) I have run it 3900 KMs. My review is based on my experience with this vehicle in past 15 months.
Prons: Only one
Looks Good
Light vehicle, Good for females and old age people
Cons:
Breaking system - Need to apply both the breaks for sudden stop otherwise it will skid
TVS service station people are useless, while servicing they are bothered only for the chceklist. They are never bothered with the any issue told by users
Fuel Tank - It is just 4 letres. If your usage is more than you need to fill fuel atleast twice a week.
There was starting issues in the begining, I had to get the batteries rechaged and got the water changed. No such issues from last six months
Neutral:
Mileage - It gives me 42-44 KM/L which is okay for me.
My usage is only 250 KMs per month with only single rider.
