On a clear highway with a lighter rider and favorable conditions, the Honda Rebel 500 can approach roughly 100 mph (about 160 km/h). Real-world speeds depend on rider weight, wind, gearing, fuel load, and bike condition.
Performance and speed factors
Speed is influenced by more than engine output. For the CMX500 Rebel, top speed is a function of power delivery, gearing, aerodynamics, and riding conditions.
The main factors that affect top speed include:
- Engine power and torque: a 471cc parallel-twin delivers roughly 46 horsepower and about 32 Nm of torque, tuned for midrange pull
- Gearing and redline: a 6-speed transmission with a relatively tall top gear helps maintain highway speeds without spinning the engine too high
- Rider weight and aerodynamics: larger riders and gear create drag that reduces top speed
- Wind, altitude, and road conditions: headwinds and high altitude reduce effective power
- Exhaust and intake condition: factory exhausts are designed for a balance of power and compliance; modifications can affect top speed
In practice, riders typically report highway speeds in the comfortable range of 70–85 mph (113–137 km/h), with rare instances near or just over 90 mph (145 km/h) under favorable conditions. Realistic top-end speeds depend on rider weight, bike condition, and wind.
Engine and performance specifications
The Rebel 500 uses the same core engine as the CB500 family, delivering a balance of power and tractable torque for everyday riding.
Key technical specifications include:
- Engine: 471cc liquid-cooled parallel-twin with DOHC and 8 valves
- Power: approximately 46 hp (34 kW) at around 8,500 rpm
- Torque: about 32 Nm (23.6 lb-ft) at around 6,000 rpm
- Transmission: 6-speed with a hydraulic wet clutch
- Final drive: chain
- Frame and chassis: steel frame tuned for a low seat height and accessible handling
- Seat height: around 705 mm (27.7 in)
- Rider weight capacity and curb weight: typically around 185 kg (408–417 lb) curb weight
- Fuel capacity: roughly 11 L (about 2.9 US gallons)
These specs illustrate the Rebel 500's focus on midrange torque, approachable power, and ergonomic highway usability rather than extreme top-end speed.
Ride and ergonomics
The Rebel 500 emphasizes an upright, relaxed riding position with a low seat height, contributing to confidence at highway speeds and stability in headwinds. The comfortable ergonomics can also influence perceived speed, as riders feel less fatigue during longer highway stints.
Note: The top speed figures are not official numbers published by Honda; they reflect typical rider experience and publicly available data as of 2024–2026. Individual results vary widely.
Summary
The Honda Rebel 500 is built for approachable power and highway stability rather than outright sport-bike top-end acceleration. In ideal conditions, it can reach about 100 mph (roughly 160 km/h), but most riders will find their practical highway speeds in the 70–85 mph range, with top-end occasionally approaching the 90–95 mph mark under favorable conditions. The bike’s torque-rich engine, comfortable ergonomics, and 6-speed transmission make it well-suited for commuting and relaxed highway riding rather than sprinting to the limit.
