Yamaha R15 has revolutionized the sport bike quarter litre segment in India. It is the first one to bring full fairing and clip ons in a 150cc bike. The bike is fun to ride with good top and low end. The riding position is too aggresive for roads and suspension is stiff which makes it uncomfortable to ride in Indian roads. Fuel efficiency is good though and light on the pocket. One thing of Yamaha is that it is always reliable. It handles well on road and is even controlable at three digit speed. It is beautiful to look at from evry angle and is desirable and that is its best selling point.
