Well! r15 v3 has little body build problem like fuel tank cover gets loosed slowly and low quality fibre is used for back wheel mud guard.
However the engine is the best thing in this bike because at 150cc range bike r15 v3 stood with a real top speed of 150kmph. (Tested)
And the best part is it’s mileage being not less than 45kmpl (tested).
So the conclusion is..
The problems mentioned are not effect the reasons for avoiding bike but the engine and style plays major role in attraction
