Honda CBF600 Service Manual (2004-2007)

Honda introduced the first-generation CBF600 range for the 2004 model year as a practical European middleweight designed around ease of use, everyday comfort and predictable road manners. Rather than chasing supersport performance, Honda positioned the CBF600 as an adaptable all-rounder for commuting, touring and newer or returning riders. The platform was offered as the naked CBF600N, ABS-equipped naked CBF600NA, half-faired CBF600S and ABS-equipped half-faired CBF600SA, giving buyers a choice between simpler naked-bike styling and greater wind protection.

The first-generation PC38 used a 599 cc liquid-cooled DOHC inline-four with a 65.0 × 45.2 mm bore and stroke, 11.6:1 compression ratio and four 34 mm constant-velocity carburetors. Power was delivered through a cable-operated wet multi-plate clutch, six-speed transmission and chain final drive. Honda tuned the engine for accessible low- and mid-range response rather than the sharper delivery of its supersport models, matching the CBF600’s role as a middleweight all-rounder motorcycle.

The chassis followed the same practical philosophy. Factory specifications list a diamond frame, conventional telescopic fork with 108 mm travel, swingarm rear suspension with 125 mm travel, 17-inch radial tyres and a 19-litre fuel tank. Seat height was adjustable around 785 mm, helping the motorcycle accommodate riders of different sizes. The S models added a half fairing and adjustable windscreen, while the N models retained a more exposed roadster layout. ABS-equipped NA and SA variants added Honda’s anti-lock braking system without changing the basic engine and chassis architecture.

This carbureted PC38 platform remained the core of the CBF600 range through 2007. Honda’s own maintenance and owner-manual archive identifies CBF600 documentation for the 2004-2007 first-generation period. The major generational break came for 2008, when Honda introduced a more compact engine, PGM-FI electronic fuel injection, a lightweight aluminium die-cast mono-backbone frame, adjustable front suspension and a newly configured Combined ABS system. Honda’s official 2008 European model announcement documents that transition clearly.

This product covers the original 2004-2007 carbureted CBF600 generation only. The factory service publication is dated December 2003 and explicitly states that it describes service procedures for the CBF600N/NA/S/SA family, while the 2008 redesign provides the clear boundary to the later PC43 platform. Related manuals are grouped in the Honda CBF600 service manual catalog, including the separate second-generation CBF600 manual.
