If you keep a casual eye on the motorcycle industry at large, then it’s hard to miss the fact that some major manufacturers are in financial trouble. But while those big brands struggle, new players emerge and a surprise success story in recent times has been that of Thunder Motorcycles. Now, straight away I can hear people asking themselves the question, how can they be successful if I’ve never even heard of them? And the answer is that the company has been focussing all of their attention on the Japanese domestic market, creating brand recognition and ensuring its product is rugged and reliable. But at the recent Tokyo Motorcycle Show, the big news came, Thunder Motorcycles are taking their pair of 250cc models global, and they’re bringing custom cool to the showroom floor.

The Thunder Motorcycles exhibit at Asia’s largest trade show for new motorcycles definitely stood out from the pack, with their unapologetically custom bike flare mixed in with traditional Japanese imagery. But the company is not solely a local effort, rather it is a joint venture between Japan and China, and takes input from some of the best custom builders from each nation. This helps to explain the fact that until now, most of the promotion for the company has taken place at shows like Mooneyes and smaller custom events. “To get the word out to the world, we need to exhibit at places with a large mass. There are so many more people here than at the custom bike shows we’ve been to before,” explains company spokesperson Yuji Noro.

But the custom culture remains a vital element of who the company are and where they draw not only their inspiration from, but also their expertise. Chief technical advisor to the brand is Takahashi-san of Kuruma Sakashita Motorcycle who has been winning the biggest trophies in the custom scene for the last few decades. And at Thunder Motorcycles, not only is he the principal dealer of the bikes and representative of the brand, but he’s also hands-on and is directly involved with the manufacturing factory, sales department, end users, and everything on the ground including training dealers and essentially serving as the outward face of the business.

“I don’t think there is anyone else who is so directly connected with so many different parties as the head of a manufacturer. But this sense of distance, knee-to-knee sitting, is important,” he says, explaining that he wants to push himself to the limits while the manufacturer is still able to do so given its size. He is also confident that if there is passion and the ability to deal with problems immediately when they arise, the business will undoubtedly grow. “If there’s a problem at the factory, I’ll go myself, not my staff. I don’t think there’s anyone else who can do that, but I think this is an important time. Once Thunder gets bigger it won’t be possible to do that, so I want to lay the foundations before that happens.”

So, now you know the backstory, let’s dive into exactly what Thunder is all about, two models, based on a single platform, with an unmistakable American style. Starting back in 2022, the first model was released, the Hardtail and its uncompromising rigid design, instantly proved to be a fan favourite. The frame itself is a long-slung cruiser, made from high carbon steel, it features a raked neck, twin downtubes and a very solid centre post to maximise rigidity while keeping the riding position narrow. This helps to achieve a low seat height of just 650mm, the same as class competitor the Honda Rebel 500, but the wheelbase of 1540mm is longer than even the biggest Rebel in the range, exaggerating the size of the bike.

And there are a few reasons this was always the goal, first, it gives the bike a long and low appearance and an element of toughness, and that helps to compensate for what is a pretty small engine. The V-Twin is just 250cc and is quite clearly based on the architecture of the very popular Yamaha XVS range of cruisers, but the Thunder powerplant is equipped with fuel injection. Now plenty might be wondering why custom builders who use big Harley engines might select such a small donk for their consumer brand. Well, the answers are numerous, it’s both cheap to produce and very reliable, it’s learner-legal and thus appeals to the whole motorcycle market, and it makes the bike exempt from Japanese vehicle inspections.

Also, this is a cruiser, those who want outright speed will look elsewhere and speaking of looks, the choice of a 74 springer front end instantly gives the bike plenty of street cred. The sportster inspired tank is another strong choice and the twin sprung seat, all help to capture the factory bobber style. The hooped strut mount for the rear fender, the big twin pipes and the under seat oil tank all keep that true American style flowing. The Bates-style headlight and vintage unit for the rear are old school, but the disc brake system features ABS and the latest incarnation of the dash is a trick digital piece.

The pricing starts at just US$5,899 for the Hardtail, while the Softail is a tad more expensive at US$6,299. And being a brand by custom builders for custom bike fans, there are plenty of factory options. You can spec a peanut tank, all manner of custom seats, a rear luggage rack, a reserve fuel container, front fender, a massive 21in front wheel to go with the factory 16in rear, all kinds of chrome and brass add-ons, and a host of new parts that are currently in production. Sales in Japan have been strong since the brand launched, and now the Thunder models are making their way to Southeast Asia, with more markets to follow. Will the brand boom or simply flame out? Tell us your thoughts in the comments section. But for us, this commuter cruiser, designed by some of the kings of the custom world, is a welcome addition to the new bike market, which is all too often boring and bland.
