It is a very useful bike in the youngers I love the yamaha r15 and it’s design & power . Around it have 150 cc and it’s milege 35 to 40 . This is good vehicle and it’s has a smooth confortness . Yamaha is one of the best bike company and their engine is more powerful compare with other kind of such companies . I talking about the power of its engine highly realable . The vehicle is more useful in the kind of youth and younger guys for their stylish movement and showing power of speed .it have only a problem that is they are produced the vehicle is 2 person but only one person is to drive back one is not easy sit in the vehicle
