What is the power output of the cr500?
The CR500 is a powerful motorcycle engine that was produced by Honda from 1982 to 1986. The engine is known for its impressive power output, which made the CR500 a popular choice among off-road enthusiasts and racers. But what exactly is the power output of this iconic engine?
Power Output Specifications
According to the technical specifications, the CR500 engine produced a maximum power output of 57 horsepower (HP) at 7,000 revolutions per minute (RPM). This was an impressive figure for a motorcycle engine of its time, and it contributed to the CR500's reputation as a high-performance, hard-hitting machine.
The engine's power was delivered through a five-speed transmission, which allowed riders to make the most of the engine's broad power band. The CR500 was known for its strong low-end and midrange torque, making it a versatile and responsive bike both on the trail and in competition.
Factors Influencing Power Output
The CR500's power output was the result of several key design features and engineering decisions. Some of the factors that contributed to the engine's impressive performance include:
- Displacement: The CR500 had a large displacement of 491cc, which allowed it to produce a significant amount of power.li>
- Cylinder Design: The engine featured a two-stroke, single-cylinder design with a large bore and short stroke, which was optimized for high-revving performance.
- Carburetion: The CR500 used a large, high-flow carburetor to deliver the necessary fuel and air mixture to the engine at high RPMs.
- Exhaust System: The bike's exhaust system was designed to efficiently expel spent gases and optimize power delivery.
These design elements, combined with Honda's engineering expertise, allowed the CR500 to produce an impressive amount of power for its time, making it a legendary off-road motorcycle.
How reliable is the CR500 engine at high HP?
The Honda CR500 engine has proven its durability over decades. With proper maintenance and a slightly rich fuel mixture, it remains one of the most reliable two-stroke engines ever built.
How much horsepower does a 2001 CR500 have?
A stock 2001 Honda CR500 produced around 56 horsepower, with some sources citing approximately 52-55 rear wheel horsepower. The CR500 is legendary for its massive torque, which is significantly higher than modern 450cc motocross bikes, though it has a narrower powerband that requires skill to manage.
- Horsepower: Around 56 hp, with dyno tests showing approximately 52-55 hp at the rear wheel for a stock model.
- Torque: The bike is known for its immense torque, producing about 25% more than a new 450cc four-stroke.
- Powerband: The power delivery is considered "explosive," with a usable power range that starts around 3,000 RPM and peaks at about 7,200 RPM.
- Performance: While not as high-revving as a modern four-stroke, the CR500's massive low-end and mid-range power make it a rocket, especially with its legendary torque.
How many horsepower does a CR500 have?
A stock Honda CR500 produced around 56-60 horsepower, with later models settling at approximately 56 horsepower, while modified versions can exceed 70 horsepower. The power is delivered in a short, powerful burst, making it a challenging but exhilarating machine to ride.
Stock models
- Initial models (1984): The first air-cooled CR500 had a claimed 59 horsepower.
- Later models (around 2001): The horsepower had mellowed to around 56 horsepower by the time production stopped.
- Rear-wheel horsepower: Dyno tests have shown stock models making around 60.15 rear-wheel horsepower, surpassing the horsepower of some modern 450s in the low-to-mid RPM range.
Modified models
- High-performance builds: Some highly modified CR500s have achieved impressive results. One example reached 61.73 horsepower on a dyno after upgrades like a stroker crank and different cylinder.
- Record-setting builds: Other builds have been reported to be even more powerful, with one reaching 72 horsepower, though this required significant modification.
Performance and handling
- Narrow powerband: The CR500 is known for its strong but narrow powerband, which can be difficult for less experienced riders to manage.
- Torque: Despite a narrow powerband, the CR500 generates significant torque, outperforming many modern 450s in this regard.
- Weight: These bikes are relatively lightweight, contributing to their agile feel on the track.

What's better, CR500 vs KX500?
In comparison to the CR 500 motor, these KX 500 motors have a little bit less hit when the power comes on so to speak. The smoother powerband makes the KX an easier bike to ride fast. Comparing to a 1986 CR 500 that has a punch when it hits the power. The 1997 CR 500 is not as punchy but still not as smooth as the KX.
