Honda CHF50 Metropolitan 2002-2009 Service Manual

Motor Scooter Guide's own history confirms exactly how directly this scooter matched up against Vespa's own contemporary offering: "the 2002-2005 Metropolitan had a decent top speed of 38mph, the same as the restricted Vespa ET2. The Metropolitan is rated by Honda at 4.9hp whereas the ET2 is rated at 5.1hp, but the Metro has a 40lbs weight advantage" — genuinely competitive numbers against a bike Honda's own retro-styled design was clearly built to rival. Wikipedia's own account confirms the deliberately borrowed styling language: "notable for its 'classic' Vespa-inspired styling and modern mechanical parts," sold under a genuinely global range of badges depending on market — "Metropolitan in the United States, the Jazz in Canada, the Scoopy in Australia and Asia, and the Crea Scoopy in Japan."

Power comes from a 49cc liquid-cooled OHC single-cylinder four-stroke engine, a 38mm bore and stroke, and a 12:1 compression ratio, fed by a 15mm-18mm CV carburetor with automatic choke and CD ignition, delivering a claimed 4.9 hp through Honda's fully automatic V-Matic belt-drive transmission. Motor Scooter Guide's own detailed engineering account confirms the genuine mechanical relationship this platform shares with another well-known Honda small scooter: "the '02–'09 Metropolitan/Jazz used a short case (small rear wheel) version of Honda's modern GET2 engine. This motor was also used in the Honda Ruckus, but with a longer swing arm" — the same fundamental GET2 engine architecture Honda developed around the turn of the millennium, adapted to a shorter case for the Metropolitan's smaller-wheel, more compact scooter application versus the Ruckus's larger-wheel, off-road-styled configuration.

Motor Scooter Guide's own account confirms a genuine restricted-speed variant sold alongside the standard model within this exact range: "from 2002 to 2006 Honda also sold a restricted speed/moped compliant version in the USA called the Metropolitan II. Honda's model code was CHF50P, with P being Honda's long used indicator of a moped restricted variant. This scooter was restricted to 25mph via a series of restrictions to the variator, ECU, intake and camshaft" — genuinely different internal tuning from the standard Metropolitan, meaning a CHF50P's variator, ECU, and camshaft are not simply detuned versions of the standard parts but distinct components built specifically for that restricted configuration.

Wikipedia's own account confirms genuinely thoughtful practical features built into the styling: "the CHF50 has a lockable center compartment below the seat which can hold a helmet (though not a full-face one). Inside the compartment is a handle to lock the center stand, making it more difficult to roll away" — a real anti-theft consideration layered into everyday storage convenience. Autoevolution's own coverage confirms this platform's genuine mechanical stability across nearly its entire production run: "between 2002 and 2008, Honda kept the first-generation CHF50 largely unchanged mechanically. Updates during this period consisted mainly of new color options, trim revisions, and small production improvements rather than major redesigns." Braking used drum brakes at both wheels with a front combined braking system, riding on 90/90-10 tires, with a 1.3-US-gallon fuel tank delivering genuinely strong real-world economy in the 90-100 mpg range and a curb weight around 176-178 lbs. Grokipedia's own confirmed pricing history lists an MSRP starting around $1,749 for the 2004 model, rising to $1,899 by 2008, before Honda discontinued this exact CHF50 platform in 2009 in favor of the fuel-injected NCH50 that eventually replaced it for the Metropolitan's later 2013 relaunch.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 2002-2009 CHF50 Metropolitan running the way it was built to.
