Honda CBF 600 S [2004-2007]: The Balanced All-Rounder That Still Wins Hearts

Introduction

The Honda CBF 600 S represents a golden era of middleweight motorcycles that prioritized balance over extremes. Produced between 2004 and 2007, this generation carved its niche as a "do-it-all" machine – a commuter-friendly workhorse by weekday and a spirited weekend companion when roads turned twisty. Even today, its formula of accessible power, Honda’s legendary reliability, and ergonomic pragmatism makes it a compelling used bike proposition. Let’s dissect why this understated legend deserves your attention.

Engine Performance: Smooth Operator with a Hint of Firecracker

At its heart lies a 599cc liquid-cooled inline-four engine – Honda’s bread-and-butter configuration refined to near perfection. With 76 HP at 10,500 RPM and 58 Nm of torque peaking at 8,000 RPM, the numbers don’t scream madness, but the delivery is where the magic happens.

The moment you twist the throttle, you’re greeted by a linear surge rather than a violent lunge. Carburetors (4x36mm CV-type) provide predictable fueling, though modern riders might miss the crispness of fuel injection. Below 6,000 RPM, it’s docile enough for stop-and-go traffic, but push past that threshold, and the engine transforms. The exhaust note sharpens, vibrations remain surprisingly muted, and the tachometer needle races toward the 11,500 RPM redline with an eagerness that defies its utilitarian image.

This is an engine that rewards mechanical sympathy. Short-shifting at 8,000 RPM? You’ll still outpace most traffic. Chasing apexes? Keep it above 7,000 RPM, and the CBF dances. The 6-speed gearbox slots with Honda’s trademark precision, though the clutch (wet multi-plate) demands a firmer pull than modern assist slippers.

Handling & Chassis: Confidence Builder for Mortals

Weighing in at 197 kg (434 lbs) dry, the CBF 600 S isn’t a featherweight, but its steel mono-backbone frame distributes mass intelligently. The 41mm telescopic fork and preload-adjustable rear monoshock (125mm travel) prioritize comfort over track-day sharpness. Yet, there’s an underlying tautness here – the bike changes direction with a nudge of the knees, holds its line mid-corner, and remains unflustered over mid-corner bumps.

Push too hard, and the limitations surface: the suspension can feel overwhelmed during aggressive corner exits, and the 240mm rear brake disc (single-piston caliper) lacks bite compared to modern radial setups. But for real-world riding – where potholes and imperfect asphalt reign – the CBF’s chassis strikes a near-perfect balance between agility and stability.

The 17-inch cast wheels (120/70 front, 160/60 rear) offer a wide selection of modern rubber. Swap the original Dunlops for Michelin Road 6s or Bridgestone Battlax, and you’ll unlock another layer of grip and feedback.

Ergonomics & Comfort: The Daily Grind Made Enjoyable

With a 785mm (31-inch) seat height, the CBF 600 S accommodates riders from 165cm (5’5”) upwards. The riding position is textbook standard: slight forward lean to the wide handlebar, neutral footpeg placement, and a well-padded seat that’s tolerable for 2-hour stints. It’s neither a cramped sport tuck nor a laid-back cruiser slouch – just honest, human-friendly geometry.

The 19-liter fuel tank (5 US gallons) grants a 350-400 km (217-248 mi) range, making it ideal for urban warriors and day-trippers alike. Wind protection from the semi-fairing (S model) is minimal but effective at legal speeds; taller riders might crave a taller screen for highway jaunts.

Design & Features: Function Over Flamboyance

The CBF 600 S won’t win beauty contests, but its design has aged gracefully. The half-fairing integrates cleanly with the fuel tank, while the under-seat exhaust (a rarity in this class) lends a sleek profile. Fit-and-finish is typical Honda – switchgear clicks with authority, panels align with precision, and corrosion resistance is above average for its era.

Instrumentation is sparse: analog tachometer, digital speedometer, and basic trip computer. ABS was optional from 2007 onward – a worthwhile upgrade given the single-piston rear brake’s tendency to lock under panic stops.

Competition: How It Stacks Up Against Rivals

The mid-2000s naked/all-rounder segment was fiercely competitive. Here’s how the CBF 600 S compared:

1. Yamaha FZ6 Fazer (2004-2009):
2. Sharper styling and a detuned R6 engine (98 HP) gave it a sportier edge.
3. Higher-revving nature demanded more aggressive riding.
4. Firmer suspension annoyed commuters but delighted canyon carvers.

5. Verdict: Better for thrill-seekers; worse for daily comfort.

6. Suzuki GSF600 Bandit (2005-2009):

7. Air-oil-cooled 599cc engine (78 HP) felt rougher and thirstier.
8. Heavier at 215 kg (474 lbs) yet more vibration-prone.
9. Cheaper to buy used, costlier to maintain.

10. Verdict: Budget alternative with higher running costs.

11. Kawasaki Z750 (2004-2006):

12. 749cc inline-four (106 HP) delivered brutal low-end torque.
13. Aggressive ergonomics and snatchy throttle deterred novices.
14. Verdict: Powerhouse for experienced riders; harsh for beginners.

Honda’s Edge: The CBF 600 S outshone rivals in mechanical refinement, ergonomic versatility, and real-world usability. While not the fastest or flashiest, it was (and remains) the most livable choice for mixed-duty riding.

Maintenance: Keeping Your CBF 600 S in Prime Shape

Owners cherish the CBF 600 S for its robustness, but neglect is its nemesis. Follow these guidelines:

1. Valve Adjustments:
2. Intake: 0.16mm ±0.03mm (0.0063” ±0.0012”)
3. Exhaust: 0.22mm ±0.03mm (0.0087” ±0.0012”)

4. Check every 24,000 km (15,000 mi). Shim-under-bucket design requires technical skill – leave to professionals.

5. Carburetor Tuning:

6. Clean jets annually if ridden sporadically. Use MOTOPARTS.store’s Berryman B12 Chemtool for ultrasonic cleaning.

7. Pilot screw: 2.25 turns out (baseline). Fine-tune for altitude/ethanol blends.

8. Oil & Filters:

9. 3.8L (4 US quarts) of 10W-40 JASO MA oil with filter changes every 6,000 km (3,700 mi). Try Motul 5100 10W-40 for smoother shifts.

10. NGK CR9EH-9 plugs last 12,000 km (7,500 mi). Upgrade to CR9EHIX-9 Iridium for sharper throttle response.

11. Chain & Sprockets:

12. 116-link 530 chain with 15T/43T sprockets. Swap to DID 530VX2 X-Ring and JT Sprockets Steel Kit for longevity.

13. Maintain slack at 25-35mm (1-1.4”) – overtightening accelerates countershaft wear.

14. Brake System:

15. DOT 4 fluid changes every 2 years. Upgrade to EBC HH sintered pads for stronger initial bite.

16. Check master cylinder seals – aging rubber causes spongy levers.

17. Cooling System:

18. Replace coolant every 48,000 km (30,000 mi) with ethylene glycol mix.
19. Monitor hoses for cracks – OEM replacements recommended.
