Motorcycle Safety & Driveability: motorcycle riding, stroke motorcycles, stroke bikes

Question
hello dear,
          hope to find u in good health.i have two questions about bikes it is generally supposed that whenever one buys a new bike he should drive it alone and there should be no second rider i.e two persons should not ride a bike till first 500 or 1000 kms why is it so? secondly i have noticed in some entertainment programes that a motorcycle is driven in a wooden or steel circular structure and i have noticed that these motorcycles are two stroke motorcycles.why dont they drive 4 stroke bikes? hope to make my point clear.

Abdul, please forgive me for being so late in this reply. Due to a partial state government shutdown, I was unable to access my email here (which is how I communicate with Allexperts).

To answer your first question, adding a passenger doubles the amount of risk. Instead of one person on a vehicle that is vulnerable in traffic, there are now two. And it's a lot easier to learn to operate the bike without the added weight of a passenger, especially when it comes time to learn to lean, brake, countersteer, swerve, and perform low speed maneuvers like weaving, U-turns, etc. Because of both of these reasons, it's best that a rider have a good deal of experience (personally, I recommend more like two years of riding experience) before attempting to ride with a passenger.

Not sure about the little bikes in the cage. Probably, two-strokes are lighter weight and make more and better power for doing tricks like that. Four strokes are generally heavier and more docile when it comes to power delivery.

Hope that helps.
