They are called governors and the answer is no, not all cars have them.
Many cars have speed limiters or RPM limiters to protect their engines from falling apart and destroying themselves. One can buy speed limiters that can be attached to the engine/ignition/fuel control. By fitting a throttle restrictor. This would have to be custom made, most garages would be able to do this work.
Rev limiters prevent damage to the engine caused by high revs.
Common cars can't do highway speeds (65 mph) in first gear and many have rev limiters.
F1, F2, F3 and perhaps all carbuerated motorcycles do not have speed limiters. Even newer fuel injected 600cc and most 1000cc motorcycles will not have speed limiters. Usual cases of governors apply to sportbikes exceeding 1 liter like the ZX12, ZX14 and the Hyabusa
Speed limiters have been shown to enhance safety among teen drivers by reducing the likelihood of speeding, which is a significant factor in many accidents. By capping the maximum speed a vehicle can reach, speed limiters encourage safer driving behaviors and help teens focus on the road rather than pushing the limits. Additionally, these devices can foster a greater awareness of traffic laws and road conditions, contributing to overall safer driving practices. Ultimately, speed limiters can lead to fewer crashes and injuries, promoting a more responsible driving culture among young drivers.
Roketa Bikes do not have speed limiters in their systems. In order to go faster, you need to change gears while in final drive.
It could be due to aerodynamic drag/ not enough HP, gearing... but most likely it is a limiter set in the engine computer. Some vehicle have speed limiters due to the speed rating of the tires they come with, for safety. Most cars are limited, the exception is high performance cars.
the government require that all new cars (and all cars, after 5 years) be equipped with speed governors that use GPS
Slow cars driven fast are always more fun than fast cars driven slow. Squealing tires, engines bouncing off limiters, dabs of oppo and elbows.
With enough speed, yes.
you have to do all races
rev limiters in the CDI are in scooters of all makes, some have a restrictor washer on the variator and a restricor on the exhaust gasket.
