Motocross racing bikeThe most efficient way to improve the handling and speed of a motorcycle is via increased operator skill. By attending riding schools and increasing rider education levels, a motorcyclist will be able to ride more skillfully and, thus, more safely. Even experienced riders can benefit from top-level instructors helping to fine-tune their skills, as well as the opportunity to practice crash-avoidance techniques in a more controlled environment (and without risking one's own motorcycle).

The next-most-common cause of loss of speed is one of the easiest to remedy: rolling resistance. The right tires kept at the proper pressure will contribute to both speed and safety.

On the engine, keep the air filter and drive chain (or drive belt) clean, use high-quality lubricants and fuel with precisely-tuned spark plugs, air / fuel mixture, and timing. This is obvious, but often neglected.

Engine modifications can yield appreciable performance improvements, but this is often costly and very time-consuming. Improper attempts at tuning can yield benefits in one particular part of an engine's power band, while impairing performance everywhere else, provoking a net loss of power or handling. Blueprinting, or meticulous restoration of an engine to (or beyond) factory tolerances can help to improve an engine's efficiency and restore power that would otherwise be lost. Enlarging cylinder head ports, while common practice amongst many tuners, is often unnecessary (unless a big-bore kit has been fitted) to the extent that many engines benefit from decreasing the volume in the cylinder head. Done correctly, this increases the velocity of the fuel / air mixture entering the cylinder, packing more mixture in per revolution.

More usable improvements can be had by improving and upgrading suspension components. Suspension is typically the one element of the motorcycle that will receive the least amount of engineering attention from the factory. Replacing stock shocks and fork springs as well as changing damping and valving rates will result in dramatic improvements in motorcycle stability and increased speed and rider confidence as a result.

Another way to increase performance is to install a tuned exhaust system. This helps evacuate the exhaust from the engine more rapidly, and permits a longer power-stroke. However many modern production bikes already have tuned exhausts. A "custom" tuned exhaust will often operate only at a narrower range of engine RPM, and therefore more suited to more specialised applications, usually racing (road or drag).

Aftermarket exhaust systems are usually louder, by varying degrees, than stock systems. Most countries have limits on how much noise can legally be produced by vehicles, however this usually does not deter motorcyclists from fitting louder exhaust systems. There is even a school of thought that louder systems are safer, as they attract the attention of (car) drivers, who might otherwise have failed to notice the motorcyclist.

One of the most effective ways of increasing power is forced induction. Turbochargers are generally more effective than superchargers because turbos spin using the exhaust gases while a supercharger uses engine power to spin it directly (usually via a belt system), robbing power. Since more air is being forced into the engine, the air/fuel ratio must be changed to prevent the engine from running lean [and potentially destroying itself]. On low boost settings, the turbocharger can increase power and fuel range. Engine internals such as pistons and connecting rods must be replaced with stronger ones for all but the smallest boost. In addition, the compression ratio must be considered and adjusted accordingly, as an "overboosted" engine will destroy itself as well.

With great care, an engine can be helped to "sprint" by injecting small amounts of nitrous oxide (N2O). The main benefits of nitrous oxide are three-fold —

More oxygen is introduced into an engine's combustion chamber
As nitrous oxide is stored in liquid form, it is still very cold when it evaporates and is mixed with fuel. This chilling effect raises the density of the mixture, packing more fuel and oxygen into the combustion chamber.
This colder mixture helps to keep the engine running cooler, which is very useful as nitrous oxide is almost exclusively used in stressful, high RPM situations, primarily drag racing.
Engines using large amounts of nitrous oxide need precise mixtures and/or configurable timing and carburation. It's very easy to blow the head gaskets or burn the valves of the engine with careless nitrous oxide injection. Using methods like nitrous oxide are fine on dragstrips, but while not illegal, can be very dangerous on the street. In any case, a canister of nitrous oxide is rapidly expended, and impractical for sustained use on a road-going bike by any sane rider.
