First of all thanks to https://mouthshut.com for providing very very useful information about bikes , reviews and friend’s opinions.
Before saying about Dazzler, let me say few words about my experience on bikes.I used 4 bikes so far, passion, unicorn, Apache and now Dazzler.Here no need to say about passion, so I will mainly say how I felt about these 3 bikes ( Unicorn, Apache, Dazzler).
UNICORN:
I used unicorn 2006 model, it was simply superb in driving, comfort, balance.No problem occurred even one time in these 4 years . Only I felt little bit heavy and normal in looks. I got mileage around 50-55.
Apache 160 FI:
I love this bike so much( especially yellow ), I brought this bike last year on july 4th , no problems with this bike, currently my brother is using this one. I like this bike because of its sound beating and stylish looks.One disadvantage with this bike is if you go beyond 80 speed, your hands start vibrating( this is my personal experience, may be others not feeling this one).Except this , this bike is very good .I got mileage around 45-50.
Dazzler:
The reason I took this bike is because of UNICORN. Same engine as Unicorn, more bhp, disc breaks, and importantly they decreased 8kg weight compared to unicorn. So it is easy to get balance now even in traffic.I used so far 350 km with 50 mileage.Surely it will go high after 2 services.
So now you decide which bike you want.
