Top Ten Lightest Bikes in 2025

Our today’s article will cover the list of Top Ten Lightest Bikes in 2025. On a motorcycle, weight—or the absence of it—is one of the most significant performance factors. Low weight, a concept Honda revolutionised with the original Fireblade, is just as crucial to overall performance as power and torque.

Weight is also critical to how manageable a bike feels. For new riders, shorter individuals or anyone who may be intimidated by large, heavy motorcycles, a lightweight machine can be a very welcome advantage. This is why many would assume that weight figures are widely publicised, consistently measured and easy to compare—but unfortunately, that is not the case.

Instead, there is ongoing confusion about terminology and a lack of uniform standards that manufacturers must follow, making it difficult to determine which figures are truly comparable. Terms such as dry weight, wet weight, kerb (or curb) weight and fuelled or dry are all used, even though they differ substantially. As a result, despite our best efforts, we fully expect some disagreement regarding this list.

Wherever possible, we have used ready-to-ride weights that contains all fluids and full tank of fuel. Unrealistic dry weights—which often exclude items such as the battery, oil and coolant—have been disregarded. We are also focusing on currently available models from mainstream manufacturers, meaning no CCM, MASH or Fantic entries, as their figures are difficult to verify. In addition, we are limiting the list to road-legal motorcycles over 125cc to avoid it being dominated by very small mopeds. Full motocross and enduro machines, even those with nominal road capability, are not included.

With those clarifications in mind, here is the list—in reverse order—of the lightest bikes based on their stated wet or kerb weights. Feel free to let us know if any deserving models have been overlooked.

Top Ten Lightest Bikes in 2025 – Top Rated

10. Royal Enfield HNTR 350 – 181kg

Introduced last year, the HNTR 350 (which is not called the Hunter in this market due to trademark restrictions) uses the same 24bhp single-cylinder engine as the Meteor 350 cruiser, but it is lighter thanks to its more straightforward overall layout. For comparison, Royal Enfield’s Scram 401 and Himalayan adventure bikes weigh 185kg and 200kg, respectively.

9. Aprilia RS660 Extrema – 180kg

The only twin-cylinder motorcycle to make this list is the premium Extrema version of Aprilia’s striking RS660 mini-superbike. With 100bhp and weight savings from features such as a carbon-fibre lower fairing, this variant offers the best performance of any model here, and it is the only proper sports bike on the list. We also expect Aprilia’s upcoming smaller model, the RS457, to appear in this weight category soon.

8. Triumph Speed 400 – 170kg

We are taking a slight liberty with this entry, as the brand-new, single-cylinder Triumph Speed 400 is not officially on sale yet; its launch is expected in January, and its price is still unconfirmed. However, journalists have already ridden pre-production examples, and the early reviews are overwhelmingly positive. Not only is this 398cc motorcycle lightweight, but it also delivers an impressive 39bhp. It is also the only way Triumph appears on this list, since the Street Triple and Speed Twin 900 are both too heavy. Its sibling, the Scrambler 400 X, does qualify but weighs slightly more at 179kg due to its scrambler-specific equipment.

7. KTM 390 Duke – 168kg

As we found previously, it is easy to fill a lightweight list with KTM models because the Austrian manufacturer builds many lightweight singles. This time, we narrowed it down since several KTMs share similar architectures. The lightest KTM over 125cc is the 390 Duke, which has been restyled and updated again for 2024. It is light, nimble and characteristically wild to ride. It also serves as the basis for the slightly heavier RC390 (172kg) and is essentially the same platform as the Husqvarna 401 Svartpilen and Vitpilen.

6. Yamaha MT-03 – 168kg

Among mainstream twin-cylinder motorcycles, the Yamaha MT-03 is one of the lightest. This engaging A2-class roadster features a 321cc twin that produces a healthy 41bhp. It is manageable, user-friendly and enjoyable to ride. For those who prefer a faired sportbike, Yamaha also offers the YZF-R3, which weighs only 1kg more.

5. Kawasaki Z400 – 167kg

Slightly lighter and more powerful than the Yamaha is the Kawasaki Z400 roadster, which was upgraded and reintroduced last year. Its 399cc twin generates 44bhp, and the bike is stylish, approachable and fun to ride. As with the Yamaha, there is also a fully faired sibling—the Ninja 400—which weighs a bit more but shares much of the same character.

4. BMW G310R – 164kg

Returning to single-cylinder models brings us to an unexpected entry in fourth place. The BMW G310R, built in India and aimed at new riders, is a charming, lightweight, straightforward roadster that is extremely easy to handle. Offering just over 30bhp, it is not the fastest machine, but it is pleasant, affordable and well-constructed with a touch of BMW refinement. Riders who prefer a more adventurous style can opt for the G310GS, which weighs 175kg.

3. Ducati Hypermotard 698 Mono – 160kg

Ducati’s first single-cylinder motorcycle in nearly 30 years is, predictably, extremely light. Determining its exact weight required some calculation since Ducati only provides a wet weight without fuel. Based on our estimates, the fuelled weight is approximately 160kg. It explains why the bike feels exceptionally quick. Its Superquadro Mono engine—which can essentially be viewed as one half of the older Panigale 1299 engine—produces an impressive 87.5bhp.

2. Honda CRF300 Rally – 153kg

Technically, the standard CRF is even lighter, but the adventure-oriented CRF300 Rally, with its tall windscreen and additional comfort features, is a much better all-round motorcycle. Both versions were initially introduced as 250cc singles before being upgraded to 300cc. For riders seeking a lightweight, off-road-capable all-rounder, this is an excellent option—just keep in mind that the KTM 390 Adventure is also a contender in this category.

1. Honda CB300R – 143kg

The lightest mainstream motorcycle over 125cc currently available is the Honda CB300R. This charming and extremely approachable machine is part of Honda’s stylish “Neo Café” lineup, which includes the CB125R, CB300R, CB500R, the four-cylinder CB650R and the CB1000R super-naked. The CB300R is Honda’s most affordable A2-compliant single-cylinder model. While it is not particularly fast, it is lively, friendly, unintimidating, built with Honda’s reassuring quality, and most importantly, very light.
