I have been using Crux since almost 8 months now. My use is mostly in city. I have been a Yamaha Fan since long and decided to buy this one after comparing other bikes in this category viz. Splendour, TVS Star City and Bajaj Platina.
Main reasons for the decision were :
Pros:
Sturdy
Stylish - I personally like its RX100 style looks
Good pickup (in this segment)
Low maintenance
Good attitude of showroom guys (I have had good experice in Pune).
Cons:
Gives problems for starting at times during morning hours (cold)
Mileage is not that great. I am getting close to 55 kmpl
Real tyre should have been wider for better grip
Overall a good bike, only issue I see is mileage is lesser than its competitors (which is not really a big issue - at least for me).
