Honda CBX 550F (1982-1985)

After the low tide the tide follows

On the finish of the 1970s, Honda retired its profitable four-cylinder, half-liter engines. The CB 400 4 was already in a position to pack in 1977, and the Honda CB 500 4 and CB 550 4 retired a yr later. The world’s largest bike producer put the – now extraordinarily iconic – Honda CX 500 with its placing V-engine available on the market as a sort of comfort.

For followers of the full of life four-cylinder fashions, the “slurry pump” was in fact not an sufficient substitute and they also have been pressured to go searching the competitors. At the moment Suzuki efficiently closed the hole between 400 and 750 cc and placed on a bestseller with the Suzuki GS 550. With its 49 hp, the mid-range Suzi was something however boring. It was technically mature and designed for an extended life. In 1979, Kawasaki adopted up with the Z 500, which knew the way to impress with its full of life 50 and 52 hp. It was adopted two years later by the Kawasaki Z 550 with extra steam from the basement.

And what was occurring at Honda? Nothing. It was not till 1981 that the main two-wheeler producer adopted up with a brand new design. The Honda CBX 400F was filled with progressive know-how, satisfied with a superb power-to-weight ratio and final however not least with an excellent look. In Germany, patrons needed to wait one other yr for the bigger mannequin, the brand new Honda CBX 550F.

The Honda CBX 550F provided temperament and intelligent know-how

With 60 hp from a displacement of 550 cc, the brand new mid-range Honda set the bar fairly excessive on this section and solely had to surrender in 1982 on the efficiency facet of the Kawasaki GPZ 550. At the moment, the promise of efficiency hid probably the most fashionable know-how – a results of years of experience of the ‘Analysis and Growth Middle’ in Asaka, Japan.

Honda’s head of improvement, Hiroshi Kameyama, donated not solely a four-valve cylinder head with two camshafts to the CBX 500F four-cylinder in-line engine, but additionally a complicated combustion chamber form. With a roof-shaped curvature (“Pent-Roof”) within the cylinder head and particular spark plugs, the brand new engine ought to burn the gas extra optimally. Along with a greater efficiency, consumption and exhaust gases must also be lowered with the brand new engine idea.

In observe, the really 572 cc engine promised a usable velocity vary between 4,000 and 10,000 rpm. Not a lot was occurring amongst 4,000 excursions. For this, the four-valve engine began all of the extra from 7,000 rpm.

“Then the 550 engine catapults the bike ahead, making it troublesome to alter gears in time. Luckily, the six-speed gearbox is straightforward and exact to change, ”was MOTORRAD’s first check.

With nearly 200 issues, the Honda CBX 550F was considerably quicker than its predecessor. Along with extra torque (48 Nm as a substitute of 41 Nm), the spirited Honda triumphed with a decrease weight.

As with the smaller CBX 400F, the intersecting manifolds of the four-in-two exhaust system are a typical trademark of the machine. What’s uncommon is that cylinders 1 and Four exhale to the left and the opposite two use the precise muffler to get rid of the exhaust fuel.

Monoshock chassis and encapsulated double disc brake

Hiroshi Kameyama donated a couple of technical refinements to the 18 inch tires. Probably the most placing factor was the brand new monoshock suspension on the rear. Through a Professional-Hyperlink deflection, the field swing arm was spring-loaded through an air-assisted central spring strut – progressively designed – which labored very properly, as MOTORRAD present in a check in 1982:

“The difficult curve mixtures present the little Honda CBX at its greatest: altering lean angles is kid’s play.”

The entrance wheel steerage is carried out by an air-assisted, hydraulically damped telescopic fork with 140 millimeters of journey and anti-dive system to keep away from annoying deflection when braking. A fork bridge straight above the mudguard, which stiffens the telescopic fork in quick cornering, offered further stability. The CBX 400F needed to do with out this not insignificant element.

The truth is, the chassis didn’t permit any weaknesses in observe and satisfied with playful dealing with, cornering stability and flawless straight operating – even at excessive speeds.

To be able to reliably brake the “athlete with what it takes to be successful” in each scenario, three disc brakes with double-piston calipers put an finish to the propulsion. Fully redesigned, the disc brakes (internally ventilated on the entrance) have been screwed on to the wheel hub and housed protectively below a vented capsule.

The experiences of CBX550F proprietor Ulrich learn somewhat otherwise than the press of these days:

My buddy on the time and I had two similar CBX550Fs from 1982 and are due to this fact very intensive and pushed to the bounds. Nonetheless, the machines didn’t have an ideal driving habits at round 170 km / h. In corresponding AB curves, a bump was sufficient to set off a daunting shake. When driving straight, she typically tended to do a (manageable) tail. We bought each of them below management by mounting the then well-known Magura clip-ons below the fork bridge and thereby putting the stanchions a couple of centimeters decrease within the fork bridges. This made the caster somewhat longer and from then on the 550 had impeccable dealing with.
