The yamaha rd 350 is truly the most powerful bike I have ever seen.The first time had a ride on it I thought I was driving a rocket.The twin cylinder bike gives a rider the highest levels of power at all times.THE RD is the all time bike i.e. the fuel efficiency was low and "Mileage is god India" so the company had to stop the production.The RD productin stopped in india because it could not satisfy the people’s needs at that time.The was costly enough and the company’s engineer’s were themselves not able to solve the problems and the most important thing that U can take it on a smooth road or on the rough roads of the world.The RD need special attention and a lot of care if a person wants a good performance from it.U need to love then it will be ur best friend and the most reliable one also.
