Fukumi Takatake – sometimes written Fukumi Kotake, born in Fukuoka, December 3, 1944 – at the wheel of the works Honda R800 during the 1969 Suzuka 500km, he finished second outright and first in the R1 class.

A very attractive car(s) new to me, the machine was of spaceframe construction, the design seemingly inspired by an F3 Brabham Honda owned by the Suzuka circuit, itself owned by Honda of course.

As the rear body-up photograph of the R800 shows below, its tiny air-cooled engine – mounted north-south at the front of the S600-800 roadies – was mounted conventionally in the rear of the sports-racer.

The cutaway drawing of the R1300 below – the engine was mounted east-west in the Honda 9 – shows the engine-transmission unit is mounted transversely at the rear as was also the case on Honda’s stunning, successful 1964-65 1.5-litre V12 RA271-272 GP machines. The suspension, brake, wheels and other specifications are otherwise 1960s period typical.

The R800 was built by Honda RSC the competition arm of Honda. The Racing Services Club was formed in 1965, then became the Racing Service Center and finally in 1982 morphed into Honda Racing Corporation. The car made its race debut that Suzuka 500km weekend and was Honda’s response to the Coniglio and Macransa (later Dome) Honda S-Series based kit/racing cars.

Shortly after the Suzuka ’69 500km race, Honda upgraded the machine by fitment of the 1.3-litre, air-cooled, four-cylinder engine fitted to their then new Honda 7/9 Coupe, a vastly underrated car. The 1300cc SOHC, crossflow, all alloy engine had a unique engine cooling system named Duo Dyna Air Cooling. The head and block had airways akin to the water passages of liquid called engines cast with short, stubby vertical fins. An impeller mounted directly to the crank pumped air through the passages, assisted by additional fins on the outside of the block. The dry sump carried plenty of lubricant, in a sense the engine was also oil cooled.

I’m having trouble finding the race record of the R800/1300, my Japanese is limited other than when excessively lubed. Information welcome.

Fukumi Takatake commenced racing motorcycles at 17 and was a contracted Honda rider at 19, winning the All Japan 250cc title in 1966. When Honda withdrew from two-wheel competition in 1967 (for a while!) he switched to four wheels, racing single-seaters, sports and touring cars. He ceased as a racer in 1987 after competing in the All Japan Touring Car Championship.

The Honda 1300 Coupe 9 was famously the last project Soichiro Honda personally led before retiring as Honda’s ‘Supreme Advisor’ in 1973.

His originality showed through in the design too, albeit times, safety and emissions legislation required a changed more conventional approach to become relevant and appealing to the masses. The brilliant Civic followed, there was nothing particularly novel about it, just great, bullet-proof engineering and build quality. Australian conditions are tough.

My Mk2 Cortina GT was the typical student shit-fighter, but it was all-mine! I felt like I was jilting a babe after a chance drive of a very affordable Coupe 9, by 1976 they were el-cheapos, high risk ones too. My big-mistake was talking to Dad about it, I needed a bridging loan while I flogged Corty and bought 9 Outta 10.

“I’ve spoken to the car guy (the Fleet Manager who thought HQ Kingswoods were edgy) at work!” he said to me the next night, here we go I thought. “He reckons you’re a bloody idiot, it will cost you heaps. You’re looking after the Ford, he reckons you’ll have to rev the ears off it – just like the last bloke did…” And so on…

So I never did buy it but man it was a nice thing. A weird mix of old-tech like the rear axle, then that out-there engine and sweet gearbox. But it was so cohesive as a package, a howling but torquey engine, shitty looking nose tho. Time to drive one again, an interesting Classic Car article perhaps…

Maybe Honda had mercy on Jack – their F2 partner in 1965-66 – saving him the embarrassment of the more obvious corporate shot! See here for a piece on that partnership; https://primotipo.com/2021/12/17/brabham-honda/

The shot says everything about the regard the BRM team had for their old driver. By that stage Richie was driving for Honda, famously the American won the very last race of the 1.5 litre F1 for Honda in Mexico City that year.

At Zandvoort the growing competitiveness of the RA272 was again on display, Richie qualified the car 3rd and finished 6th, the race won by Jim Clark’s Lotus 33 Climax.

The BRM’s finished 2nd and 4th, Stewart in front of Hill, both in P261’s. Dan Gurney was 3rd in a Brabham BT3 Climax.

Soichiro Honda was a talented engineer who created the largest motorcycle manufacturing company in the world, it could be said that he helped mobilise the masses in many Third World countries. He was a passionate racer and in the early 1960s challenged the dominance of the European motorcycle marques, notably MV Agusta, on the circuits of the world.

By that time Honda R&D already had a 2.5-litre Cooper T53 Climax F1 car to tinker with (above) and study, they announced their entry into Grand Prix Racing in 1964, a sensational 1.5-litre transversely mounted V12 stressed-skin chassis car their weapon of choice.

Honda had already started building road cars – the S600 and S800 sports cars – and by 1972 built their first Civic, a car which didn’t revolutionise the class but brought amazing standards of refinement and performance into the market for the time. It was the first of many outstanding mass market cars which would define the marque as the Japanese BMW in the eyes of many.

Honda were on a climb and motor racing was part of the plan to develop innovative technology, resilient engineers and promote and build the Honda brand.

Honda RA271…

The chief engineer of the project was Yoshio Nakamura, later to become Honda’s CEO.

The initial prototype, the RA270F was a spaceframe car, derivative of the Cooper, and was tested extensively at Arakawa on 6 February 1964 and then Suzuka, by many including Jack Brabham. Brabham and his partner, Ron Tauranac were to race Honda 1-litre, four cylinder engines in their F2 Brabhams, winning the ‘European F2 Championship’ – there wasn’t an official one until 1967 – in 1966.

In fact Honda had decided to be an F1 engine manufacturer, not the builder of their own chassis and had entered into a partnership with Lotus, but problems with Lotuses existing Ford agreements precluded contract execution by Lotus…so Honda built the chassis after all.

The definitive RA271 used a stressed skin monocoque chassis which ended at the rear of the cockpit to which was mounted the transverse 60 degree 1495cc V12. A tubular subframe picked up the rear suspension assembly which could be unbolted and wheeled away.

The engine was DOHC, four-valves per cylinder and was fed initially by six Keihin carburettors mounted across the frame behind the cockpit. Fuel injection was being developed and was soon adapted to the engine. Power takeoff was by spur gears from the centre of the crankshaft driving directly into a transverse shaft six-speed transaxle.

Front suspension was by top rocker operating inboard mounted coil spring damper units and a lower wishbone. The rear was by way of reversed lower wishbone, single top link with outboard mounted coil spring damper units and two radius rods providing lateral location. Sway bars were adjustable front and rear. Dunlop disc brakes were used and Goodyear tyres, Honda and Brabham were the first users of Goodyears in F1.

Ronnie Bucknum…

Somewhat bizarrely, the Japanese, as if to emphasise the experimental nature of the program, chose Bucknum, a little known American sportscar driver with single-seater experience, to pilot the car. His family owned a Honda dealership in the US and he raced an S600 at home, these days a Superlicence would not have been issued!

He tested the car extensively in Japan before the car’s first race in the German GP, at the Nurburgring. What a baptism of fire for car and driver in August 1964!

Bucknum qualified the RA271 slowest, no disgrace in that, and then drove a steady race in the wet, the power curve of the engine was somewhat peaky, he was in 11th place when a steering problem caused him to crash out of the race.

The team missed the Austrian GP but returned with the definitive fuel injected version of the engine at Monza, qualifying mid-grid and racing in fifth before overheating problems intervened. In the US he retired with a blown head gasket to finish the teams truncated first season.

1965, the final year of the 1.5-litre Formula…

Honda were more serious about its 1965 campaign, building a new car, the RA272 and signing Richie Ginther ex-BRM and Ferrari, and a noted test and development driver to lead the team, retaining Bucknum for a second year. The team were based in Amsterdam, the centre of Honda’s distribution operation in Europe.

The power of the engine was increased from circa 220bhp @ 11000rpm to 230bhp @ 12000rpm with chassis weight reduced by 30kg. Minimising heat build up became key as the engines lost power significantly as the races wore on, Ginthers ‘banzai’ starts came to nought as the engines lost grunt.

The cars appeared at Monaco, qualifying up the back and both dropped out, Richie with a UJ failure and Ronnie with gear change maladies.

The Belgian GP was typically wet, Ginther qualified fourth and finished sixth while Bucknum’s transaxle failed. Both cars failed to finish at the French GP with ignition problems although Richie qualified seventh.

The Honda was well suited to the wide open spaces of ex-RAF airfield Silverstone, one car was entered for Ginther which he duly qualified third and led from the start, the Honda yowling its way out front. He ran third for much of the race but again ignition problems ended his race.

Ginther again qualified third at Zandvoort and led the race but then spun twice and finished sixth. Honda missed the Nurburgring, but reappeared at Monza with engines mounted lower and using sleeker bodywork, Bucknum qualified sixth and Richie 17th after various dramas. Both popped engines again failing to finish. Both cars finished for the first time at Watkins Glen in the US Grand Prix, Bucknum an uninspired 13th and Richie seventh having again qualified third.

And so, onto the last race of the season and of the 1.5-litre formula. The Magdalena Mixhuca circuit at Mexico City was the venue for the Mexican Grand Prix, famous for the difficulties caused to engines at a height 7500 feet above sea level.

Ginther again! qualified third and Bucknum tenth. At the drop of the flag Richie simply took the lead and ran off into the distance, the little jewel of an engine never missing a beat and scoring Honda’s, Goodyear’s and Ginther’s first Grand Prix victories. Bucknum was a strong fifth. Hondas fuel injection system, problematic at times was one of the reasons for the Mexican success, thriving at the higher altitude.

And so Honda won a famous and well deserved win and would be back late in 1966 with a heavy but powerful 3-litre V12 engined car, the RA273…

As an enthusiast I love those marques which have racing as part of their DNA, for that Honda have their founder to thank. Soichiro Honda gave the following press conference speech after the Mexico win, I love the insights it provides into his thinking about how racing improves the breed.

He said, ‘Ever since we first decided to build cars we have worked hard and been willing to take the most difficult path. Now we must study the reasons why we lose, and do the same when we win, so that we can use that knowledge to improve the quality of our cars and make them safer for our customers. That’s our duty. Once we had established our goal, we decided to choose the most difficult path to get there. This is why we entered the Grand Prix series. We will therefore not be content with this victory alone. We will study why we won and aggressively apply those technologies to new cars’.
