Overview

Introducing the 1978 Honda CB 400 N: a captivating fusion of performance and practicality that embodies the spirit of the late 70s sport motorcycle scene. Positioned as an accessible entry into the world of performance motorcycling, the CB 400 N was designed to appeal to both novice riders and seasoned enthusiasts alike. With its sleek lines, nimble handling, and an impressive power-to-weight ratio, this bike stands as a testament to Honda's commitment to engineering excellence and rider satisfaction. At the heart of the CB 400 N lies a spirited 395cc twin-cylinder, four-stroke engine that delivers a respectable 27 horsepower at 7,500 RPM. This engine, with a compression ratio of 9.3:1, offers a delightful balance of power and efficiency, allowing riders to experience exhilarating acceleration while maintaining fuel economy. With a top speed of 137 km/h (85.1 mph), the CB 400 N is more than capable of keeping up with the demands of spirited riding. The bike's 6-speed gearbox ensures smooth shifting, while the air-cooled design adds a touch of classic charm, making every ride a nostalgic journey through the open road. The CB 400 N isn't just about raw power; it also boasts an array of features that enhance the overall riding experience. The single disc front brake provides strong stopping power, instilling confidence for both city commuting and weekend adventures. The lightweight chassis, tipping the scales at just 184 kg (405.7 pounds) when fully fueled, coupled with a 14-litre fuel tank, makes this motorcycle remarkably agile and easy to maneuver. The bike's three valves per cylinder design optimizes air intake and exhaust flow, contributing to its lively performance and responsiveness, while the classic aesthetic captures the essence of its era. **

Pros

  • Compact and Lightweight: At just 184 kg, the CB 400 N offers excellent handling and maneuverability, making it an ideal choice for both new and experienced riders.
  • Reliable Power: The well-engineered engine delivers a satisfying balance of performance and efficiency, making it suitable for both city commuting and spirited rides.
  • Classic Styling: With its timeless design and Honda's renowned build quality, the CB 400 N stands out as a stylish classic that appeals to collectors and enthusiasts alike.

Cons

  • Limited Power for High-Speed Touring: While adequate for city and spirited riding, the 27 HP may fall short for those seeking high-speed touring capabilities.
  • Single Disc Front Brake: Although adequate, the braking system may not match the performance of modern dual-disc setups found on newer sport bikes.
  • Comfort for Long Rides: The sport-oriented seating position may not be the most comfortable for extended journeys, as it prioritizes agility over rider comfort.
