Overview

Introducing the 1981 Honda CB 250 RS, a classic naked bike that captures the essence of lightweight, nimble motorcycling. Designed for riders seeking a blend of practicality and excitement, this model firmly established Honda's reputation in the mid-sized motorcycle market. With its sleek, minimalist design and user-friendly characteristics, the CB 250 RS is ideal for both novice riders and seasoned enthusiasts looking for a reliable commuter or a playful ride through twisty backroads. At the heart of the CB 250 RS lies a spirited 248cc single-cylinder, four-stroke engine that delivers a respectable 26 horsepower at 8500 RPM. This spirited powerplant not only provides lively acceleration but also showcases Honda's engineering prowess with a well-balanced compression ratio of 9.3:1, ensuring efficient fuel combustion and smooth performance. Coupled with a 5-speed gearbox, riders can easily navigate through city traffic or cruise at a top speed of 146 km/h (90.7 mph) on highways. The air-cooled engine keeps things straightforward, while the lightweight chassis, tipping the scales at just 148 kg (326.3 lbs) with fluids, allows for agile handling and a responsive riding experience that will delight those who thrive on corner carving. The CB 250 RS is adorned with features that enhance both its functionality and aesthetic appeal. Its single disc front brake offers powerful stopping performance while maintaining a lightweight profile. Meanwhile, the rear expanding brake complements the bike's handling dynamics, providing balanced braking capabilities. A generous fuel capacity of 13 liters (3.43 gallons) enables longer rides without frequent stops, making it an excellent choice for weekend adventures. With its 4-valve cylinder head, the engine not only promotes efficient airflow but also adds to the bike's spirited character, ensuring that every twist of the throttle feels engaging and alive. **
