Vehicle Information
Honda Metropolitan 50 Scooter (2002-2026)
The Honda Metropolitan 50, a popular urban scooter, has been a staple from 2002 to 2026, evolving through distinct generations. Initially, from 2002 to 2009 (CHF50), it featured a 49cc liquid-cooled, carbureted four-stroke engine. A brief hiatus was followed by its reintroduction in 2013 (NCH50), showcasing an entirely new design with an air-cooled, fuel-injected 49.4cc engine until 2015. The latest iteration, from 2016 to 2026 (NCW50), reverted to a liquid-cooled 49cc four-stroke engine, now with programmed fuel injection, alongside updated styling and increased storage. Throughout its production, the Metropolitan has primarily been offered as a single model, with variations mainly in color. The "Metropolitan II" (CHF50P), available from 2002 to 2006, was a restricted-speed variant for moped compliance, not a separate trim level with different features. These generational shifts represent significant changes in engine technology and design, ensuring the Metropolitan remains a versatile and efficient choice for city commuting across its long production run.
