Master Class: 1970 Triumph TR6 Bobber
Heiwa Motorcycle’s Triumph TR6 “Parrot Star”…
The Triumph TR6 was the single-carb version of Triumph’s 650 twin, originally known as the Trophy and then as the Tiger from 1969 onwards. While the dual-carb Bonneville received most of the limelight, the TR6 would become the quintessential desert sled for off-road racing in the United States, and many riders came to prefer the Trophy / Tiger over the Bonnie:
For 1970, there were four models in the TR6 lineup: the standard TR6, TR6R roadster, TR6C (competition) street scrambler with high pipes, and the TR6P police version. In a period test, the TR6R ran the quarter-mile in 14.2 seconds at 92 mph and went on to a top speed of 103 mph — solid numbers for a single-carb twin of the day.
Of course, the 1970 TR6 Tiger you see here is a far cry from original. It’s the work of one of Japan’s most respected custom builders, Kengo Kimura of Heiwa Motorcycle. Kengo began riding motocross at the age of 10. When he was 23, a fractured femur forced him to retire from racing, but he’d started working in the custom department of a local shop and opened his own workshop, Heiwa Motorcycle, in 2005.
Over the years, Kengo’s two-wheeled creations have brought him international renown, and he’s well known for Triumph TR6 customs like his “MasterPeace” and “Dirty Pigeon” builds, which both took “Best in Show” at the prestigious Yokohama Hot Rod & Custom Show (Mooneyes Show).
Now Kengo is back with this gorgeous 1970 TR6 bobber dubbed “Parrot Star,” which was exhibited at the 2023 Mooneyes Show. Really, only the engine is from 1970, as Kengo fabricated the single-downtube, mono-shock frame and swingarm himself.
The one-off oil tank hides the rear shock, giving the bike the look of a rigid bobber, and there is none of the empty triangle look here. Rather, the side covers house a custom air cleaner.
Up front, there’s a set of Kayaba forks, and the bike is rolling on custom-laced 2.5-19″ (front) and 2.5-18″ (rear) wheels with a Robinson 2LS (dual leading shoe) front hub / drum brake.
The engine has been highly modified as well. Says Kengo:
Kengo always builds some of our favorite exhaust systems, and this one pays tribute to the high-mounted scrambler exhaust of the TR6C, with a gentle, lovely rise toward the rear and integrated heat shields.
The paint is the work of Shakin’ Speedgraphix, who laid down the olive green metallic and dark green metallic colors.
The tank was hand-hammered from aluminum, made to sit nice and low on the backbone of the frame, and so many other elements of the bike are one-off creations: the tail section, headlight cowl, top yoke with integrated risers, handlebars, pegs, controls, oil tank…the list goes on.
Birds of peace — including pigeons, doves, and paper cranes — are important to the culture of Hiroshima, and Heiwa Motorcycle’s logo bears a painted bird. So it comes as no surprise that winged tings turn up in the names of many of Kengo’s projects: “Dirty Pigeon, Bull Pigeon, etc.” This one he’s dubbed “Parrot Star.”
This TR6 custom was a highlight of the Mooneyes Show — the work of a master craftsman at the top of his game. We’re honored to feature it, and a special thanks goes out to Kimura-san himself and our friend Kaz Matsumoto (@steeldog_photo) for the gorgeous photography. Enjoy!
