Honda CBX 1000: The Six-Cylinder Superbike

The Honda CBX 1000, first unleashed upon the world in 1979, remains a legendary machine, celebrated for its audacious engineering and exhilarating performance. At its heart lies an engine that was, and arguably still is, a masterpiece of motorcycle design: a transverse six-cylinder powerhouse. This wasn't just a bigger engine; it was a statement of intent from Honda, a desire to push the boundaries of what a production motorcycle could be. Owning or even just experiencing a CBX 1000 is to touch a piece of motorcycle history, a testament to an era where innovation often trumped practicality, resulting in machines that stirred the soul.

The Heart of the Beast: A Six-Cylinder Symphony

The defining characteristic of the Honda CBX 1000 is undoubtedly its engine. Honda engineers opted for a four-stroke, transverse six-cylinder configuration. This meant that all six cylinders were arranged in a line, running across the frame, perpendicular to the direction of travel. This layout, while visually striking and technically impressive, presented unique challenges in terms of packaging and handling, but the payoff was immense in terms of smooth, powerful delivery.

Displacing 1047cc (or 63.9 cubic inches), this magnificent powerplant featured a DOHC (Double Overhead Camshaft) setup, with four valves per cylinder. This meant a total of 24 valves, all meticulously orchestrated to breathe life into the engine. The DOHC design allowed for better control over valve timing at higher RPMs, contributing to the engine's impressive power output.

Power and Performance Figures

The CBX 1000 was a performance king in its day. It produced a formidable 105 horsepower (76.6 kW) at a screaming 9000 revolutions per minute (RPM). The peak torque figure was equally respectable, delivering 71.8 Nm (52.27 lb-ft) at 6500 RPM. These figures translated into a top speed of 218.8 km/h (135.9 mph), a speed that was truly breathtaking for a motorcycle in 1979. The power delivery was known for its smoothness, a characteristic often associated with multi-cylinder engines, but the sheer number of cylinders in the CBX created a unique and addictive experience.

Key Engine Specifications Compared

To truly appreciate the CBX 1000's engineering, let's look at some of its vital statistics:

Beyond the Engine: Chassis and Handling

While the engine grabbed most of the headlines, the chassis and suspension were crucial in harnessing the CBX's immense power. The motorcycle weighed in at 247 kg (544.5 lbs) dry, a significant heft that required a robust frame and competent suspension. The front featured an air-assisted fork with 160 mm of travel, allowing riders to fine-tune the front end's stiffness. At the rear, an adjustable dual-damping swingarm handled suspension duties, providing 100 mm of travel.

Braking was equally impressive for the era. The front boasted twin 276mm discs, providing substantial stopping power, while the rear featured a single 296mm disc. These components were essential for confidence-inspiring deceleration, especially given the bike's performance capabilities.

Wheels and Tyres

The CBX 1000 rolled on 19-inch front and 18-inch rear wheels, shod with tyres sized 3.50 x 19 at the front and 4.25 x 18 at the rear. These dimensions were typical for sportbikes of the period and contributed to the bike's overall handling characteristics.

Rider Experience and Legacy

The Honda CBX 1000 wasn't just about raw numbers; it was about the experience it offered. The sound of the six-cylinder engine was a unique, high-pitched wail that set it apart from anything else on the road. The smoothness of the power delivery, combined with the sheer torque available, made for an intoxicating ride. However, its sheer size and weight, coupled with the expense of its advanced engineering, meant it was a niche machine, appealing to riders who craved exclusivity and unparalleled performance.

Reviewers and riders of the time often praised its incredible engine and smooth performance, though some noted that its weight could be a handful, particularly at low speeds. The maintenance cost, or 'Maintcost' as indicated in some rider feedback, could also be a factor due to the complexity of the six-cylinder engine.
