Forced induction on a motorcycle is a forced induction application (turbocharger or supercharger) to a motorcycle engine. Special automotive engineering and human factor considerations exist for forced induction applications by motorcycle, compared to other forms of motorized transport.

Forced induction in motorcycle production
In September 2014, new forced induction was applied to several production motorcycles, all from the Japanese Big Four manufacturers in the early 1980s.
- Honda 1982 CX 500 Turbo/1983 650 Turbo
- Yamaha 1982-1983 XJ 650 Seca Turbo
- Suzuki 1983 XN 85 Turbo
- Kawasaki 1983-1985 GPZ750 Turbo
In addition, in 1978 Kawasaki offered Z1R-TC, a semi-manufactured model built by Turbo Cycle Corporation and sold through Kawasaki dealers. This is generally regarded as Japan's first turbocharged motor.
Motor Honda, Kawasaki, and Suzuki are all listed on the "State of the Agricultural Insurance blacklist" list published by American Motorcyclist in 1989.

Kawasaki said it would re-enter the market with the supercharged Kawasaki Ninja H2, announced in October 2014.
Challenges of technique and usability
Designers have been able to overcome the packaging problem and fit the turbocharger even in a fully faired motorcycle.
Turbo lag was noted as a problem with all four Japanese turbos in 1980 by some critics. Motor engineer and journalist Kevin Cameron says turbo lag is a critical issue with turbocharger applications on motorcycles: "[U] you're not a pure drag racer, most of you rode off-boost, lower your compression ratio, less snap Your bike will have... do not expect your turbo bike to be widely used in sportbike type canyon racing. "Using variable-geometry turbochargers can reduce turbo lag, but it has not been used in series production (the first mass-market application was for late 1980s cars ; see Turbocharger-geometry # History and usage examples).
Writer Mick Walker has listed turbo lag along with other challenges such as higher center of gravity and heat transfer to rider due to turbocharger and related exhaust pipe. Bennett notes heaviness and excessive complexity in addition to weak bottom-end performance.
The German magazine Motorrad said in 2014 that turbochargers may never be practical on mass market motorcycles because of the cost of high-tech materials capable of withstand high temperatures from variable geometry turbochargers, plus weight and space considerations, even though they allow doors open for a good supercharged solution.
Emissions
Emissions considerations, driven primarily by the carbon dioxide limit in European emission standards, were the leading motorcycle manufacturers in 2010 to reconsider the application of forced induction.

In the race
In road racing, superchargers were not uncommon in the 1930s, and machines originally built for street racing also set many ground speed records (see list below for an example). Motorcycle racing in Europe underwent a hiatus during the 1940s as World War II and as a result, and the race only resumed in 1946. That same year, forced induction was banned from street races by FÃÆ' Â © dation Internationale de Motocyclisme (FIM) effectively moving it to a special form of racing and speed running record, discussed further below. The regulations of the FIM and other sanctions bodies include various aspects of motorcycle design such as fairing of motorcycles, direct injection of gasoline, and the use of dual-clutch transmissions, and may affect the design of a road bike by setting public expectations.
Drag race
Special motorcycles used in drag racing, called dragbikes, are applications for forced induction, including nitrous oxide and multistage turbochargers. The first dragbike that runs quarter mile in less than 7 seconds using Roots type supercharger.
