I have been using this for nearly a year now and I can vouch for most members who state that the mileage is poor. I get around 32kmpl vs. claimed 55kmpl. However, it was not(and is not) the biggest decision maker for me.
Braking: Works well. Have to be careful during rains. Ive had to get this worked on with every service.
Build quality: Above average. Is sturdy and gives you that feel.
Looks: Great. Better than most in class.
Features: I especially love the front-fuelling & good boot space. My 15" laptop fits snugly! I also love the electronic display. Big selling point for me.
Mileage: Very poor. With leaded fuel(speed / power) it gives around 32kmpl.
Reliability: In the last one year, Ive only had a problem with starting twice. Having said that, my battery died just recently and had to get it replaced.
Service center: Not very efficient. They dont really do the checks they are supposed to.
Ride comfort: It is alright. The poor ground clearance means I have to be careful when going over bumpy roads. The handle grip could be better spaced from the seat for more comfort.
Engine: Best part of the vehicle. Quick and responsive. I can get upto 80kmph without the effort like in an Activa. Is really zippy.
My verdict: It is an honest attempt by Mahindra to get marketshare, but is it leaves a lot to be desired in mileage and after sales service. Mahindra has to pick the right partners to sell & service the product to gain trust of customers. The features it already has(larger boot, zippy engine, electronic display) make for a premium scooter in the market. Hopefully, Mahindra will make efforts to improve it further.
