The Super Cub is back

The greatest motorcycle ever.

With 100 million made and counting it’s great news that Honda’s Super Cub motorcycle is being reintroduced in the US. The original dates from 1958.


The original ‘step through’ bike. This is the new version.

The step through design meant that ladies did not have to show their undergarments to all and sundry when getting on – or getting off for that matter – and Honda paired the roll-out with the greatest motorcyle campaign ever.


The greatest bike ad ever – June 1963.

The Super Cub was revolutionary in so many ways it’s hard to know where to begin. It had a four stroke engine whose low compression ratio made the use of the lowest octane gas possible and obviated the need for an electric starter, which was an option. The plastic fairing, a first, provided excellent weather protection for the rider and the top speed of 40+mph was all you needed in crowded western and eastern cities. The chain was enclosed to keep oil off the rider’s legs and the DIY maintenance was so simple anyone could perform it. The semi-automatic gearbox deleted that pesky clutch, meaning even women could ride the Super Cub when not in the kitchen or in labor.

But it was that magical advertising campaign which made all the difference. Watch The Who’s ‘Quadrophenia’ and you see warring mods – on scooters and neatly dressed – fighting rockers – on bikes and in leather jackets – beating one another up in Brighton. What else was there to do in early 1960s London on a weekend, after all? Then along comes Honda with this:


Not just for poor eastern nations.

This was fun transportation for people who did not have grease in their hair or under their fingernails and who dressed like nice preppies in upper end western hemisphere culture.

That $215 in 1966 was actually a bargain. Using CPI data that computes to $1,675 today whereas the Super Cub is coming back to the US at $3,599. But you get a tremendous increase in technology and reliability compared with the already reliable original. The 50cc engine is now 125cc, the brakes are hydraulic disks, not drums, all lighting is LED, ABS is standard and was but a dream 50 years ago, the wheels are cast not spoked and the tires are the far safer tubeless variety as a result. Fuel injection? But of course.

My Honda scooter, bought 15 months ago and now with 2,000 miles on the clock may look fancier but the Super Cub is a classic.

Do the environment a favor and help destroy Middle East and Russian hegemony over oil supplies. Get a Super Cub and extend your life expectancy.

Electronic surprises in 2018

Some great devices.

The digital world marches on and much as I fight the tide with a solid adherence to an analog, mechanical universe, there’s no denying that digital technology is superior in every way, despite having the personality and charisma of a washing machine.

One of the costliest additions to the digital household at the beginning of the year was a 65″ LG OLED TV. Thinner than an iPhone it starts very quickly, delivers blacks the likes of which were heretofore unobtainable on a television and, unsurprisingly, is reliable as a refrigerator. While I confess to being slightly discombobulated with the occasional exhortation on turn-on to update the operating system, the device is a delight to use. We are rapidly approaching the day where that 100″ projection screen setup I installed in the vineyard home will become affordable in a big screen TV. The price one year ago was $2,697. The set now retails for $2,349, a modest drop of 13% reflecting the difficulty of making fault free large OLED panels. And did I mention it’s thinner than an iPhone?


The 65″ LG OLED TV.

That big screen TV was accompanied by a pair of special electrostatic loudspeakers, as capable of rendering shoot-’em-up action as they are in plumbing the depths of Horowitz’s Steinway. There is a lot of overpriced trash in the high end speaker sector. Martin Logan has been around for ever and appears financially stable.


A very special loudspeaker – the Martin Logan ESL.

And because those electrostatic panels are not that good at moving the large volumes of air dictated by low bass notes, the main speakers are accompanied by the desirable adjunct of a powered sub-woofer.


The Martin Logan Dynamo 700 subwoofer. Low notes are rendered correctly.

But it’s always something and both the main speakers and sub-woofer demand lots of clean power so the Parasound stereo amplifier, 5 year warranty and all, joined the team:


The Parasound integrated stereo amplifier.

This outfit has quickly become second nature, taken for granted like a good camera and lens.

And speaking of cameras and the analog world, what could be more analog than film? I blame two friends for my film rediscovery this year, the one a film fanatic and prof at CalTech, the other an AV technologist in Boston with a fine eye who sent me some rolls of Kodak’s Ektar. I went about the hardware discovery process in the best American tradition. I threw money at it. So I snapped up a Nikon FE, A Nikon N90S and a Nikon F100, to see which spoke to me loudest. The FE was lovely but I really missed AF as my eyes are not what they were. The N90S came in a lovely compact package but refused to speak to my old chipped MF Nikkors on those increasingly rare occasions where I brave manual focus. But the F100 proved to be the bee’s knees, a perfect melding of digital technology (AF, auto exposure) and film. Money? Film bodies are so inexpensive that after selling the FE and N90S I was but $150 out of pocket.


The finest film camera made. The Nikon F100.

Not least of the F100’s beauty is that the controls and layout are almost identical to those of the D700, Nikon’s first FF DSLR and one I reverted to after selling the big and clunky D3x. Sure the D3x delivered 24 sharp megapixels, but I really did not need those, any more than I needed the truck-like weight. The D700 boasts but 12 high quality megapixels and boy do they ever work.


The Nikon D700 – available for very little in mint condition.

Finally, long time readers will know that I am a confessed long time motorcycling addict. My 1975 BMW R90/6 is now in its 29th year with me and absent newer shocks remains pretty much in original condition, right down to the antique but perfectly capable mechanical points ignition. The sole nod the BMW makes to the electronic world is a couple of $1 relays to preclude frying of the wiring harness when the 120dB Italian FIAMM horns are worked to alert left-turning morons in cars that a two wheeled human being is headed their way.


My 1975 BMW R90/6. A product very much of the mechanical age, with awful instrument lighting.

But this year the miserably weak instrument lighting, a small sub-chassis containing a myriad of minuscule incandescent light bulbs prone to failure and hell to access for replacement, gave way to an LED harness. This was invented by a lady rider who had grown mightily frustrated with the constant failure of her stock lighting harness, not least the fact that if the generator bulb fails that it takes the whole ignition system with it. Who thought that up? Anyway, that frustrated lady rider happens to have a spouse who is expert in CAD/CAM and he came up with an LED bulb chassis which is a drop in replacement for the stock one, is so bright that I can finally, after 29 years, see my high beam indicator in bright sunlight, and which will certainly outlast me and the bike.


The stock and KatDash LED lighting harness for the BMW Airhead.

And while I am mixing analog and digital, you should know that both my tachometer and speedometer failed within weeks of one another at 63,000 miles, expertly repaired by the geniuses at Palo Alto Speedometer at considerable expense. At least I will not have to crack the instrument housing again. For all their charm and charisma, no one could accuse analog devices of coming with low maintenance costs.

iPhone you ask? Why yes, I was forced to upgrade my iPhone 6 by a felonious maker who made it so slow with software ‘upgrades’ as to be useless. I switched to a used iPhone 7 for a net cost of $300, thus denying said felon my money while reclaiming the lost speed at reasonable cost. No more new iPhones for me.

The GOAZ vintage bike show

A day in the sun.

Motorcycles used to be single brand things in the store. In the UK of my youth any self respecting high street would have several such stores from Triumph (died in 1983), BSA (1972), Matchless (1966) and Royal Enfield (1971) for the lowest demographic, through to the Velocette (1971), AJS (1969) and Norton (1975) stores for the higher tuned machines with racing aspirations, then onto the high end which meant Vincent (1955) and BMW (which continues merrily to this day).

With one exception, all the great British marques failed owing to crappy engineering, with little reinvestment in modern production machinery and newer designs, the same curse which destroyed most of British industry while louche aspirants to power like Margaret Thatcher saw to it that Britain became a financialized nation centered in London, making precisely nothing, while shuffling paper denominating debt and real estate.

The one exception was Vincent which went under because of that generic British curse, lousy management. But without doubt, above all these self-inflicted wounds, the one machine which destroyed British motorcycle manufacture was the Honda CB750 of 1969, an across the frame, air cooled four which did all the things British machines did not. It started first thing, sported a powerful engine, had an electric starter, was reliable as a hammer and never leaked oil. Honda got there after making smaller predecessors like their fine 125, 175, 250 and 400 multis, all leading up to the killer 750.

So now the high street line up – this is the early 1970s – found one brand stores from Honda, Yamaha, Kawasaki and Suzuki, the ‘Big Four’, all making superb, powerful, beautifully executed multis. And, of course, BMW, with its staid but reliable and oh-so-well-made twins.

Then the accountants started to take over and today the single brand store no longer exists, unless you consider Harley-Davidson and the ever failing Indian. We can disregard those as they are restricted to PTSD sufferers who were once pawns of the Pentagon, fighting yet another losing war while having their guts vaporized along with their grey cells, such as they were.

They buy motorcycles not to ride but to commiserate.

For the other big name manufacturers, the chances that you will find many brands under one roof are high. One such (very large) roof is GOAZ Motorcycles near my home in Scottsdale, Arizona where on one lot you will find Triumph (resurrected and alive), BMW, Aprilia, KTM, Ducati, Vespa/Piaggio, the Big Four and Ducati. And let’s not forget the Ural, a Russian piece of garbage with a sidecar sold only to the criminally insane.

Every fall, in the first week of autumn (the start of our riding season, as you can no longer fry an egg unaided on the sidewalk), GOAZ holds a vintage motorcycle show where exhibitors (like me) are required to pay a $15 entry fee to show their old machines. Strange economics. Shouldn’t the gawking visitors be paying? It’s a fun show not least because Harleys and their owners are not welcome (there’s the world’s largest HD dealership next door for these knuckle draggers, complete with tattoo parlor and wedding chapel. The dealership actually makes more money from clothing sales than from bikes but the profit leader is the service section because, you know, Harleys make pre-war British bikes look like exemplars of reliability. No, I am not making any of this up.)

The 2018 fall show was held today and my much ridden 1975 BMW R90/6 was again on display, accompanied by lovely old Ducatis, Benellis, Moto Guzzis, British bikes aplenty, lots of vintage Japanese iron, Vespa and Lambretta scooters and on and on.



Just one of the many marques sold at the gigantic store.

The ‘Goose’ in all its splendor. Beru spark plug cap is the right one. The asking price of $15,000 was 100% too much.


Architectural design touches on a Benelli 250 four, a two stroke screamer that could top 90mph in 1975.


British and Best. The 1954 Vincent Black Shadow. The speedometer is not just for show.
The bike, however, is for show only, as the low post-restoration mileage and accompanying trailer testify. Ugh!


Detail of the 1000cc V-twin in the Vincent. Known as the ‘plumber’s nightmare’ for good reason.


Wishful thinking, for the Vincent’s brakes were reluctant to do anything of the sort.


A tribute to the welder’s art. Exhaust junction on a Kawasaki Turbo.


Exquisite exhaust routing on the bejeweled 1975 Honda CB400 four, one of the machines which buried the British motorcycle industry.

your fillings do not fall out while a compression release makes the kick-starter usable.

Still bright chrome explains why these cost so much back in the day.

The air cooled twin

BMW, of course.

BMW has been making motorcycles with air cooled twin motors since 1921. While the line was discontinued in 1995 in search of more power for children who think that 100hp is called for in a single track vehicle, the design layout continues in air and oil cooled twins to this day from the BMW factory. Sure the charm and light weight have been lost but the design is as right today as it was almost a century ago.

The 900cc motor at left is in a 1975 R90/6 which is now in my 29th year of ownership. The fully faired touring rig on the right is a tad larger at 1,000cc. Both develop around 60hp, perfectly adequate for touring at 70mph all day long. The beauty of these air cooled twins is that the cylinders are way out there in the air stream, so no oil or water cooling is called for. While the later machine sports a small oil cooler it’s quite unnecessary in practice. A related benefit is that the design means that the center of gravity is very low indeed, making maneuvering at low speeds child’s play. Try horsing that high mounted Japanese ‘across the frame’ four around at parking lot speeds and you will get my drift.

Each cylinder has its own carburetor, as is clear in the image. These share the same technology present in the 1921 version and are as reliable as a hammer. Periodic valve lash check-ups and adjustments are very easy as the valve covers are simply removed (two nuts and one bolt), giving full access to the valves and followers. Rapacious and unnecessary demands for ever more power doomed these machines, which remain firm favorites with touring riders for their quietness, freedom from vibration and comfort. 300,000 miles on one of these engines is no big deal.

The last time horizontally opposed, air cooled motors were used in cars was in the original four cylinder VW Beetle and four and six cylinder Porsches, before both went to water cooling. The modern Subaru uses the design in a water cooled variant and the motors are also famously long lived.

Bartlett Lake, AZ

In the Tonto National Forest.

Bartlett Lake is 35 miles northeast of Scottsdale and is deserted on weekdays. The ride through the high desert is lovely, and while the 20 mile approach road through the Forest has seen better days the gentle sweepers and absence of traffic make for a fine opener for the 9 month motorcycling season here, now that daytime highs have dropped to the low 90s.



No traffic in sight.

The Last Stop is the only dining place at the lake. Usual burger fare.
Note the matching 1975 historic registration plate on my 1975 BMW R90/6,
now in my 29th year of ownership and a delight to ride.

Boat and JetSki rentals are available.


This was the first occasion on which I aired out the camera in my ‘new’ iPhone7. In contrast to the 8mp files from the excellent camera in the iPhone6, iPhone7 files are 12mp and what little grain there was in iP6 images has disappeared, the crazy azure skies have been tamed a bit (if not quite enough) and resolution is everything you would need for the largest of prints. An incredible technical accomplishment.

The miserable CEO of Apple, Tm Cook, a man devoid of original ideas, claims that one of the justifications for the crazy pricing of the latest iPhones is that you get a great camera thrown in. Well, there’s no question the camera is fine (albeit with the world’s worst ergonomics) but I’ll stick with a separate SLR when conditions get challenging. But for a day-to-day snapper the camera in the iP7 is exceptionally good.
