Honda CB 900 F (1979-1980) Review: A Timeless Powerhouse Revisited

Introduction

The Honda CB 900 F, produced from 1979 to 1980, stands as a monument to an era when motorcycles began transitioning from utilitarian machines to icons of performance and style. Known affectionately as the "Super Dream" in some markets, this inline-four powerhouse bridged the gap between the raw, unfiltered bikes of the early ’70s and the polished, technology-driven machines of the future. Even by today’s standards, the CB 900 F remains a compelling blend of muscle and mechanical simplicity—a bike that rewards riders who appreciate analog thrills. Let’s take it for a spin.

Design: Classic Lines with a Touch of Brutality

The CB 900 F’s design is unmistakably late ’70s: a muscular fuel tank with knee indents, a flat bench seat, and a squared-off tail section that screams “function over flair.” The 815 mm (32.1-inch) seat height feels accessible for most riders, though the 260 kg (573 lb) wet weight becomes apparent when maneuvering at parking-lot speeds.

The chrome accents, wire-spoke wheels, and twin shock absorbers out back give it a purposeful, no-nonsense aesthetic. Compared to modern bikes, the CB 900 F feels industrial—a machine built to be ridden hard, not polished for Instagram. The analog gauges (speedometer, tachometer, and basic warning lights) are refreshingly straightforward, though night visibility is mediocre by today’s standards.

Engine and Performance: The Heart of a Legend

At the core of the CB 900 F lies its 902 cc DOHC inline-four engine, producing 95 PS (70 kW) at the crank. This air-cooled beast wakes up with a deep, guttural bark from its four-into-one exhaust—a sound that’s been muted in modern bikes by emissions regulations. Throttle response from the four Keihin carburetors is immediate but not abrupt, with torque building linearly from 3,000 RPM.

The powerband is broad, pulling strongly from 4,000 RPM up to its 9,500 RPM redline. Cruising at 120 km/h (75 mph) feels effortless, with the engine humming at a relaxed 6,000 RPM. The lack of fuel injection means you’ll need to pamper the choke on cold mornings, but once warmed up, it settles into a steady 1,000 RPM idle.

Notable Specs:
- Compression Ratio: 8.8:1 (modest by today’s standards, but forgiving on regular fuel)
- Spark Plugs: NGK DR8ES (standard) or DR8EIX (iridium upgrade)
- Cooling: Air-cooled—no radiators to fuss with, but heat soak in traffic is real.

Handling and Ride Quality: A Study in Contradictions

Weighing 260 kg (573 lb), the CB 900 F isn’t a flickable sport bike, but it hides its mass well once moving. The 35/37 mm telescopic forks and preload-adjustable rear shocks offer a firm yet compliant ride, absorbing bumps without wallowing. Tire pressures matter here: Honda recommended 2.25 bar (32.6 psi) front and 2.5 bar (36.3 psi) rear—stick to these for optimal grip and stability.

At highway speeds, the bike feels planted, though crosswinds can push around the narrow, 19-inch front wheel. The drum brake out back lacks bite compared to modern discs, but the front dual-piston calipers provide adequate stopping power with a firm lever pull.

Competition: How Does It Stack Up?

In its heyday, the CB 900 F faced fierce rivals:

1. Kawasaki Z1-R (1978-1979):
2. Pros: Larger 1,015 cc engine, more aggressive styling.
3. Cons: Heavier (275 kg), less refined vibration.

4. Verdict: The Z1-R is brasher, but the CB 900 F’s smoother power delivery ages better.

5. Suzuki GS850G (1979-1980):

6. Pros: Shaft drive (lower maintenance), comfier seat.
7. Cons: 10 PS weaker, softer suspension.

8. Verdict: The Suzuki is a better tourer; the Honda prefers backroads.

9. Yamaha XS1100 (1978-1981):

10. Pros: 1,100 cc engine, factory fairing option.
11. Cons: Porky 291 kg, dated handling.
12. Verdict: The Yamaha’s a torque monster, but the CB 900 F feels nimbler.

The Honda’s balance of power, reliability, and aftermarket support makes it the most versatile choice for modern classic riders.

Maintenance: Keeping the Legend Alive

Owning a 40+ year old motorcycle requires vigilance, but the CB 900 F is famously robust. Here’s what to prioritize:

1. Valve Adjustments:
2. Intake/Exhaust Clearance: 0.06–0.13 mm (0.002–0.005 in) when cold.

3. Frequency: Every 4,800 km (3,000 miles). Use a feeler gauge—tight valves cause misfires; loose ones clatter.

4. Oil Changes:

5. Capacity: 4.3 L (4.5 qt) without filter; 4.5 L (4.75 qt) with.

6. Recommendation: SAE 10W-40 conventional or semi-synthetic. Modern oils improve shift smoothness.

7. Carb Tuning:

8. Air Screw Setting: 2 turns out from seated. Sync carbs annually for optimal idle.

9. Chain Care:

10. Specs: 106-link chain with 17/43 sprockets.

11. Tip: Replace with an O-ring chain for longer life.

12. Brake Fluid:

13. Type: DOT 4. Flush every two years to prevent corrosion.

MOTOPARTS.store Recommendations:
- Upgrade to NGK DR8EIX iridium plugs for hotter sparks.
- Swap stock shocks for adjustable aftermarket units (we stock Koni replacements).
- Install a spin-on oil filter adapter for easier changes.
