I am the owner of unicorn, really happy with performance. Still I did not find any other two wheeler in 150cc segment better than unicorn. It is the best ever.The following accessories I replaced in the 5th year
self starter carbon bush
speed meter cable
chain adjustments
I am getting the mileage of 50km/LTR avg.
in City: 40km-50km speed: 50km/LTR
long drive: 70km-80km-90km speed: 45km/LTR
Very consistent performance till now.I driven 80km non-stop on long drive, did not give any trouble.and I felt very comfort driving.My usage is 40km everyday up and down, I never feel tired on driving.
If anyone would like to buy 150cc segment bike, go for honda unicorn.
