Dear Friends;

“What should be the driving speed of new bike/car” is a question for which different mechanics have different answers. Some mechanics recommend that drive the new bike/car less than 50km/h speed until first 1000kms running so that piston may get sufficient clearance. Other mechanics recommend that no problem, you can drive as much speed as you drive a normal bike/car.
So which is the best way? Please reply with sufficient detail.
 
I think you are asking about the "break-in period" of a new engine. A decent break-in will help prolong the life, fuel mileage, and performance of any engine, and isn't much different from daily city driving. Three "bad" things to do to a new engine are a constant rpm for long periods[like highway driving], long periods of idling, and high revs of the engine.
After the break-in period of the vehicle, the constant speed isn't an issue, but really high rpm's will shorten any engines life.

During the break-in, the pistons rings basically wear down to the point they become "seated" well. This is accomplished by the rpms of the engine being varied, like stopping and starting in traffic. An occasional trip up the highway will do some good too.
Break-in periods are listed in the manual that comes with the vehicle, and can vary greatly. One final thing to remember, the first few oil changes should be done sooner than the normal time/miles after the break-in.
