Honda's route to stardom

It was back in 1969 when Honda introduced the first four-cylinder 750cc motorcycle the CB750.

Honda wasted no time once they realized what they had and quickly followed this bike with the beautiful CB500/4 in 1971, then maybe the least loved, and for good reason, in 1972 the CB350/4, this being superseded by the amazing CB400/4, an unbelievable machine for the day which was adored by so many. 

The CB400/4 was developed in tough times for Honda having limited R&D funding but still featured, for the first time, a six speed box, something the CB500/4 never had although Honda did add it to the 550 engines realising it was needed. Another striking change was the sweeping four into one exhaust pipes, such a recognisable feature and one people today still see as quite dramatic. 

The 400/4 showed the new sleek racing style of Honda which was a move away from the CB350/4, CB500/4 and early CB750/4's being smaller, lower front end and a more agile sporty bike by the whole.

The CB400/4 was no match for the KH models or other  2 strokes of the day but what it lacked in raw speed it rewarded it's owner far more in refinement, reliability and smoothness.

It was a bike that had a surprisingly short sales life being discontinued allegedly for exhaust regulations, sound familiar, in 1978 after some 100,000+ models were sold worldwide.

The bikes were followed by a new Honda 550/4 F2 Supersport and a 750 versions, both using the sweeping four into one exhaust and very similar sporty appeal.

The inline four cylinder Honda's revolutionised the motorcycle engines of the day, They were soon surrounded by Suzuki GS550, 750 and 1000cc models, Kawasaki Z650's, 750's, notably 900's and 1000cc models to name a few. To say Honda broke the mold is unquestionably true and the mold would never be the same again.

 

We look back at these times with real affection, today they just don't make bikes with the charm, charisma and certainly chrome that they did back then, Okay say we are bias, agreed we probably are but that doesn't mean were wrong!

The Honda CB500/4

Why did Honda reduce the size of their bikes and engines, we are referring to the '69 launch of the iconic CB750/4, when the trend of the day was bigger, faster and generally the more nuts the better and make the 500cc version, the CB500/4? 

If you think that this comment is a bit simplistic we take your point as it probably is, we argue that you should look to the CBX brought out a short time later, it was launched in '78, and you can see where the Honda designers were looking towards with this, the most unreal inline six engine, 6 carbs to balance, like as if, we were just blown away, can this get any more surreal? Honda gave the guys at MCN one to test at the launch, I guess knowing full well what they had and we were treated to her on the front cover of MCN spinning her rear wheel changing up a gear at 100MPH! I know I cannot ever forget it, unbelievable. 

Back to the plot, so with all of this to come reduce it they did and they did it because feedback on the 750 was probably negative on the overall bulk and sheer mass of the thing, remember they were taking on the Triumph's of the day, they must have wondered if they had this one wrong? The CB750/4 was, and still is today a thing of beauty, but like the Victorians, who liked a bit of large, it had been on no diet, in fact, again like the old Victorians, it was showing off its size as a thing of beauty, which it was for both we feel, but to ride her, steady on, was a different matter. The CB 500/4 was a considerable 80 pounds lighter than the CB750/4 and that made a real difference back then as it does today.

Although the new CB500/4 was destined to be made only for a short time, information conflicts on this online however it was launched in 1971 and we currently own a 'P' reg, although we think a '75 exactly when it left the Honda factory is unknown and we have heard 1978 as the last date but we doubt it, certainly in the UK as the K6 came along in '74 then the CB550 F1 in '75 and F2 in '78 and of course a CB750 F1 in '77 which was certainly around the UK streets in '78. 

So we got this amazing bike, looking back together with the 400/4 was surely Honda at it's most inspired moment, she was manageable, no moped to be fair but she would easily knock around town without constant attention, on the open road she was always lacking a 6th gear for me but you could easily up the rev range and you were rewarded with a bucket full of enthusiasm she had stored away waiting for you all along. Her frame was a frame of the 70's so let's not get excited but she would fall into corners at low speed and stay fairly stiff in high end ones, no Italian but decent enough for the day.

Braking was a single disc, pathetic in todays terms but again it stopped you, albeit sometimes there was room for improvement shall we say.

The bike was a great bike of the day and even now will keep you happy enough on an open road, but that was not her trump card, that was her beauty and boy oh boy did she play that one right, she was a looker.

It todays world of same old same old vehicles this era was indeed special, every stroke of the designers pen appears to have had flair in it, look at the tank, the way it gracefully marries the seat to the yoke, the pipes, a four into four with tulip designs on the ends, these were made for a purpose, to look amazing and they did. The whole bike from any angle looks right, even from above, see the image below.

 

 

So the world was treated to this iconic machine, beauty, power, handling, agility she had it all. Once you rode the CB500/4 you were hooked, it was a pungent cocktail of the like we had never seen before, mine was a really poor example back in the day, see the grainy image below sporting four into two aftermarkets with some dubious modifications and mostly ran on 3 in the wet but I loved her, for me she was my magic carpet and strangely I feel every bit the same today,.

People of the modern world I give you the Honda CB500/4, more than just an old motorcycle your dad used to ride, it's a piece of art which to this day still finds itself at the centre of attention for all the right reasons.
