Are the Triumph Struxon 400 and Tracker 400 the Main Attraction? [Owner Review: 5 Years of Motorcycling Experience, Riding a Scrambler 400X]

The Triumph Struxon 400 and Tracker 400 are finally on display and available for test rides at dealerships across Japan. Drawing on my experience at the overseas test ride event held in Spain this spring, I’d like to take another look at these models from the perspective of a Scrambler 400X owner.

Heading to Málaga, Spain, to attend the Triumph 400 overseas test ride event

Amid a global trend of increasing mid-displacement models, it was announced in the summer of 2025 that the Triumph 400 series would expand to a lineup of four models with the addition of the new Street Triple 400 and Tracker 400.Having welcomed the Scrambler 400X as my ride in the spring of 2024, I heard this news and seriously considered the Struxon 400.

While the 1200cc model bearing the “Struxon” name—which is practically synonymous with café racers—was announced to be discontinued in 2024, it’s fascinating to see it making a comeback in the 400 series.On a personal note, this is my fifth year riding. Although I obtained my large-displacement license at age 40, I’m well aware that my skills aren’t quite up to par yet. I believe a mid-displacement bike is just right for me if I want to enjoy motorcycling safely and for the long term. That’s exactly why I felt that, with a bike of this size, even I could enjoy riding with clip-on handlebars more.

Just as I was thinking this, Triumph Japan reached out to me, asking, “Since you ride a Scrambler 400X, would you like to come to the overseas test ride event for the new 400?” So off I went to Málaga, Spain.

I’ve been riding the Scrambler 400X for about two years. The only modifications I’ve made to the stock bike are installing engine guards and high-mount mudguards, and replacing the chain. I’ve put about 10,000 km on it.

Upon arriving at the hotel in Spain, a Racing Yellow Tracker 400 was symbolically placed in the entrance, as if to welcome guests.

On the first night in Spain, we listened to presentations on planning, development, and design. Both the Straxon and the Tracker are models with a rich heritage, and the presentations included anecdotes while reflecting on Triumph’s history.

The next morning, we attended the orientation and headed out for a test ride! Our group started with the Thruxton 400. I had a photo taken with Anri (Instagram @anritocamp), an influencer who joined us for this event.

The evolved "TR Series" engine—the Slacston 400 delivers a sense of unity with the bike

Before diving into the test ride report, let’s review a few details.Triumph’s 400cc Modern Classic series features the 398cc liquid-cooled single-cylinder DOHC 4-valve “TR Series” engine. The initial lineup consisted of the Speed 400 and Scrambler 400X, and this time, the Streetfighter 400 and Tracker 400 have been added to the lineup.

While each of the four models in this 400 series has its own distinct character, the first point worth noting is that the Thruxton 400 and Tracker 400 are equipped with the “TR Series” engine, which has been upgraded from 40 hp to 42 hp.When I was offered this opportunity for an overseas test ride, my biggest concern was: “Even though I’ve ridden the 40-horsepower Scrambler 400X, will I even be able to tell the difference with this 42-horsepower upgrade?”

So, I set off with a bit of trepidation, but that doubt vanished almost immediately after test-riding the Slugston 400, which has a higher-revving engine. At low speeds in the city, the characteristic single-cylinder pulse and easy-to-handle feel remain unchanged, but the response when opening the throttle on the open road is incredibly exhilarating—powerful and smooth.With acceleration that defies its 400cc class and a well-balanced ride that feels effortless, I immediately realized I really liked this bike.

The Triumph Thruxton 400 makes a strong impression with the contrast between its classic round LED headlight and bar-end mirrors, along with its compact rocket fairing. It’s equipped with Pirelli Diablo Rosso Quatro tires, which convey a pure passion for speed.

As the only Triumph 400cc model to feature clip-on handlebars, the Thruxton 400, combined with its slightly rearward-set footpegs, naturally creates a forward-leaning riding position. However, there’s no need to feel uneasy about this position.The bike’s responsive handling and natural power delivery combine to create a riding experience so effortless that it almost makes you feel like your skills have improved. The sense of unity between rider and machine—different from my usual Scrambler 400X—made for a truly enjoyable test ride.

The seat height is 795 mm. Compared to the Speed 400, the riding position features clip-on handlebars that are 40 mm narrower and 246 mm lower, while the rear footpegs are positioned 86 mm further back and 27 mm higher. This requires a more aggressive, forward-leaning riding posture.

The Tracker 400 brings a relaxed and laid-back feeling

The Tracker 400 features a design that openly inherits the DNA of American flat-track racing, with wide, flat handlebars, a sleek fuel tank silhouette, and side number plates. The seat height is 805 mm, which is 30 mm lower than the Scrambler 400X (835 mm).The riding position is slightly forward-leaning, with a wild style that keeps your elbows out. I felt a little bewildered at first, but it didn’t take long to get used to it.

The tires are Pirelli MT60RS, designed primarily for on-road use but capable of handling rough surfaces as well.

Perhaps because I had just test-ridden the Scrambler 400, the Tracker 400 felt even more approachable.Considering its versatility—from commuting and daily use to weekend medium-distance touring—I highly recommend it. Compared to the Scrambler 400X, it offers better ground clearance, which helps make it accessible to a wider range of riders.

Triumph, embodying solid British design, also offers attractive pricing

Personally, I really love the solid, rugged presence of Triumph. The style, which pursues practicality and durability without losing its refined elegance, is alive and well in this 400 series.While it is the most casual model in the brand’s lineup in terms of both price and specifications, seeing the actual bike reveals that its build quality and attention to detail are on par with other models.

The engine’s character has been revitalized through an increased redline and revised power delivery in the high-rpm range. Maximum output has improved by approximately 5% compared to the previous model, peaking at 9,000 rpm (up from 8,000 rpm).

The cockpit features a combination of the analog speedometer and LCD tachometer common to the 400 series. It is also equipped with a USB-C charging port.

The Tracker 400 features a striking "400" race number and a cool, sculpted tank with knee grips.

Both the Struxon 400 and Tracker 400 feature front forks with a black anodized finish. Newly designed wheels complete the modern look.

The Tracker 400 is available in three colors: Phantom Black, Racing Yellow, and Aluminum Silver. 809,900 yen (Phantom Black), 822,900 yen (other two colors)

The Struxon 400 is available in four colors: Phantom Black/Aluminum Silver, Pearl Metallic White/Storm Grey, Carnival Red/Aluminum Silver, and Metallic Racing Yellow/Aluminum Silver.849,900 yen (Phantom Black/Aluminum Silver) 862,900 yen (other 3 colors)

The starting price for the Streetfighter 400 in Japan is 849,900 yen, while the Tracker 400 starts at 809,900 yen. The ability to purchase a motorcycle with such refined design, equipment, and brand prestige for under 900,000 yen is a major draw.

The Speed 400 and Scrambler 400X have sold a cumulative total of 150,000 units worldwide in the two years since their launch. The Slugton 400 and Tracker 400, strategically introduced following that success, are sure to provide further momentum for the Triumph 400 series.With these expectations in mind, I look forward to the opportunity to ride the Thruxton 400 through Hakone.

The Scrambler 400X also started running very smoothly around the time I finished the break-in period. If you get one brand-new, I hope you’ll savor that process as well.
