Why do you want to increase your budget to 75k, when there are products that satisfy your requirements in 65k? please go out with open mind, test ride the available bikes, then take a decision based on that. By blocking out brands/products even without taking a test ride, you may possibly lose out on a product that would have otherwise served your purpose to T. And I don't understand why anyone would want to spend 75K on a Stunner FI, when there are other bikes, which can do far better are available for much less (both on mileage front & performance front).

i already said, i can increase budget, 75k can be done,
but still confused between
sz-r, dazzler n stunner FI...
Definitely go for Honda DAzzler or the unicorn.. Both has the mileage u want. dazzler has style looks performance less maintanence,rear discs... go for it. SZ-R is also good but you won't get the mileage that you want .max 53 you will get

Vrugonnab: sorry, but i didn't understand what u said.....would you please elaborate....and which bikes are you referring to...thanks

Sir go for Dazzler. IMO its the best 150cc bike (barring R15 ofcourse). No bike would give you so smooth engine and nice power with superb shockabsorber. Only downside is looks like Twister
If not buying Dazzler then pls try out Discover ST. Its much better product than earlier discovers (Earlier discovers were not bad). Its refined, Its powerful, fuel efficient, monoshocks,4 valve engine and reviews are very positive. Total paisa vasool. Putting that solid option out would be like a crime.

Just for a city bike, you can checkout Discover series 125ST/150 or P135LS, all these fall in your budget and they are popular models in market (of course 125ST is still new). Your main criteria seems to be a decently powerful city bike with 55 kmpl mileage in city. I'm pretty sure that the 150cc bikes (i.e. Unicorn, Dazzler) you are considering or for that matter any of the 150's will not return that kind of mileage in city(yes, including Discover 150). I've used P135LS in Bangalore, it used to give me 55kmpl + consistently (used to be 58kmpl most of the times). By virtue of similar 4-valve engine as that of P135LS, I do expect Discover 125ST to return identical mileage figures. Can't vouch for Discover 150's mileage, but it should easily return around 50kmpl going by ownership reports. Now don't pounce on me for recommending all Bajaj products , I feel in your budget these are the most VFM bikes, you can very well go for SZ-R, but mileage may or may not be as per your expectation, on the other hand SS125 was also known for poor mileage in it's previous avatar as Gladiator, not sure if it's improved in it's new avatar, but it's a very good bike. I don't recommend Shine/Stunner to anyone, they are just not good enough if you go above 60kmph, not that you get a chance to do so in city. But it feels good to know your bike is upto it if needed. I would look for maximum performance bike as long as mileage criteria is satisfied and if that's the case with you, Bajaj products should find a place in your test ride short list.
