Ultimate 300cc Two-Stroke Shootout: Top Dirt Bikes

Hey everyone, it's always an exciting time when new dirt bikes hit the scene, especially when discussing the thrilling 300cc two-stroke enduro machines. These bikes offer a fantastic blend of power and agility that many riders, from casual enthusiasts to seasoned off-road rider pros, just can't get enough of. We recently came across a really insightful 300cc two-stroke shootout that gave a clear look at some of the top contenders for 2025; you'll learn what makes each of these sport motorcycles tick, and which ones might just be calling your name. The folks over at Australasian Dirt Bike Magazine put together an awesome comparison at the Goulburn Motocross Complex. They didn't just stick to the MX track, a common testing ground for a motocross bike; they also used an enduro loop out back. This is great because it gives a well-rounded view of how these bikes perform in different off-road riding conditions. Understanding this varied testing ground is important when you're looking at the results of any 300cc two-stroke shootout. One really smart thing they did was split their tests. This particular showdown focused on trail and race performance, crucial for any race bike. They're planning another one specifically for hard enduro, where features like a radiator fan become even more critical. Why? Because these are very different styles of riding; hard enduro often means slow, technical crawling, while trail and race riding is generally faster, sometimes demanding a good sixth gear. A bike that shines in one might not be the top pick for the other, so separating them makes total sense, especially when evaluating overall engine performance and handling characteristics. Meet the 2025 Enduro Contenders Let's get familiar with the bikes that were put through their paces. It's quite a lineup, with some familiar faces and a very interesting newcomer to the off-road bike scene. Each bike brings something a little different to the table, showcasing varied approaches to engine mapping and suspension philosophy. Fantic XE300 Two-Stroke First up, we have the Fantic XE300. This isn't just any Fantic; it's the new injected version, a significant technical overview point for the brand. The testers hadn't ridden this specific model before, so there was a lot of curiosity surrounding its TPI fuel system. It's always exciting to see how a manufacturer approaches fuel injection on a two-stroke, particularly how they manage the power valve activity for smooth delivery. TM300EN Then there's the TM300EN. This bike was their up-spec injected model, though TM also offers a carbureted version. This high-tech one was chosen for the test. TM bikes often stand out for their craftsmanship and distinctive character; you can find more about TM's approach on sites dedicated to European motorcycle brands. The Austrian Powerhouses: KTM, GasGas, and Husqvarna Of course, you can't have a shootout without the Austrian brands. We saw the KTM, a GasGas ec, and a Husqvarna in the mix. Interestingly, the Husqvarna on hand was a 250cc model, perhaps a Husqvarna TE. They couldn't get a 300cc Husqvarna two-stroke for this test, but they decided to include the 250 anyway, offering a point of comparison for riders considering different cc dual sport options. Beta RR300 Racing The defending champion, the Beta RR300, was also there to defend its title. They had the Racing version, the rr race model, for this trail and race shootout. Beta has a strong following, and for good reason; for their upcoming hard enduro test, they plan to use Beta's rr x-pro version, highlighting again how different bike setups suit different disciplines. The Beta RR line is well-regarded among enduro enthusiasts. Sherco 300 SE Factory Last but not least, the Sherco 300 SE Factory. This is Sherco's top-tier offering, often referred to as the se factory model. For 2025, Sherco is also bringing in a "Racing" version, which is a bit of a throwback. But for this comparison, and their future hard enduro one, they stuck with the Factory model, known for its high-end components and race-ready build. Sherco bikes are known for their strong performance in enduro competitions worldwide. The 300cc Two-Stroke Shootout: Rider Impressions After a full day of riding on a dusty but manageable enduro loop, the test riders gathered to share their thoughts. It's these rider-specific insights that really paint a picture of each bike's strengths and weaknesses, beyond just a technical stuff list. Let's see what they had to say about how each bike feels on the track and trail. The Upstart Fantic XE300 Skibbo, one of the testers, was quite impressed with the Fantic. He felt that for a first attempt with this TPI (Transfer Port Injection) system, Fantic did a fantastic job. He mentioned it was "as close to a carbureted feel that you can get in 2025," which is high praise for an injected two-stroke, as many riders miss that classic carb response. This TPI fuel delivery system aims for efficiency and smooth power. He highlighted the Fantic's superb chassis balance and brilliant fork action, with good progressive damping. And when the bike "gets on the pipe," referring to when the power valve opens and the engine hits its sweet spot, he loved the sound from its cone pipe, saying it made him feel "like a 16 again." He certainly felt it was a fast bike. GB and Briggsie, known as the "racer boys," agreed it was quick once it hit the mid-range and top-end, showing strong engine performance at higher RPMs. But, they also noted it lacked a bit of bottom-end power compared to the Sherco and the Beta, which could be a factor in extreme riding scenarios. When asked about downsides, Skibbo reiterated the lack of bottom-end for harder, technical terrain where precise throttle control is paramount. Graham found the five-speed gearbox a bit tricky. He often found himself "hunting around" between second and third gear, suggesting the gear ratios might not be perfectly suited for all conditions or that a sixth gear might have been beneficial. Because of the flat bottom-end power, he thought he'd struggle with it in hard enduro. Another rider pointed out the aluminum frame; after riding steel-framed bikes, the Fantic felt "a little bit more active in the suspension" and somewhat cramped, even if it didn't look that way. The perceived stiffness of an aluminum frame can translate to a different ride than more flexible steel frames. The Reigning Champ: Beta RR300 Racing The Beta RR300, the previous year's winner, made a strong case again. Briggs immediately called it "fast" and "race-ready." He was on the KYB-equipped Racing version, which clearly means business, suggesting its stiffer suspension is built for speed. He even suggested it was probably the fastest bike there, a testament to its potent motor and well-sorted chassis. The Beta RR line is well known in these comparisons. Skibbo found the Beta to be the "cleanest running carby of the lot," indicating excellent jetting and engine tuning. He genuinely couldn't find much to fault with it. Gibbo, who rides a Beta at home, unsurprisingly named it his favorite bike of the day. He praised the twin-spark plug head for making it run super clean, even cleaner than his 2023 model, which is a neat piece of technical stuff. He found power everywhere and excellent front-to-back balance, critical for a confident off-road motorcycle. He didn't even have to think about the suspension, equipped with renowned KYB suspension components; it just worked. This often indicates a well-balanced rear suspension linkage system and front fork setup. Graham, usually a KTM rider, was new to KYB suspension but had heard good things from many a dirt rider. After riding the Beta, he admitted that when he got back on the Austrian bikes, he realized the KYB setup felt better to him. He found the Beta's power delivery good and its balance quite nice, especially considering its carbureted nature in a field with many TPI bikes. The bike also likely features a Selle Dalla Valle seat, known for comfort and grip, which adds to the premium feel of the rr race edition. Oil injection is also a standard convenience on modern Betas, simplifying fuel-ups. The Austrian Contingent: KTM, GasGas, and the Husky 250 Moving to the familiar orange, red, and white bikes, Graham kicked things off. His favorite of the three Austrians was actually the Husqvarna 250, a capable cc dual sport sibling. He said if it were a 300, perhaps a Husqvarna TE 300, he'd be very happy. He liked its bottom-end feel, which is crucial for technical sections. The KTM, which was the Six Days or Champions edition (a top-spec race edition model), felt "super aggressive" to him. He wondered if the map switch was on an aggressive setting or if the stock engine mapping was just that potent. He did praise its incredible front brake, a key component for any serious off-road rider. The GasGas EC, however, didn't impress Graham as much for serious enduro. He described it as an entry-level bike that lacks essential equipment like a skid plate and handguards, meaning the initial price tag might be lower but additional investment is needed. You'd have to spend more money right away to protect the bike properly. But, Skibbo had a different take on the Gas Gas. He thought the GasGas ec was a "fantastic trail bike" and could ride it all day at slower speeds. He called its open cartridge fork the best stock one he's ridden under 60 kilometers per hour, perfect for trail riding, though perhaps not up to par with the WP Xplor components found on higher-spec KTMs. So, its suitability really depends on your needs, budget, and desired skill level. Briggs picked the KTM as the standout from the Austrian trio. He felt it was the best all-rounder. He could happily trail ride it, but also push it into race mode, thanks to features like its adjustable power valve. He thought its fork was the best of the three, noting the revised closed-cartridge design as a definite improvement, feeling more like a KYB setup, potentially even better than some WP Xplor forks for aggressive riding. Its balance was a strong point, and its electric start and hydraulic clutch are benchmark. He put it in contention for bike of the day, alongside the Sherco and Beta. Geoffrey, with lots of experience on KTMs, felt the 2025 TBI (Throttle Body Injection) two-strokes are the best KTM has ever made. He believes they're the closest they've come to recapturing the excellence of their older carburetor models. He found the KTM incredibly easy to hop on and feel comfortable; everything from clutch action (likely a Brembo hydraulic clutch) to brakes and suspension, including the rear suspension PDS shock or linkage system, felt right. He particularly noted the improved forks making the balance spot on. For him, on that specific track, the KTM was a top choice for an experienced off-road rider. The Italian Enigma: TM300EN The TM300EN seemed to be a bit of a polarizing bike. Graham found it "a difficult bike to ride." He described its power delivery as problematic, going from off the bottom to top-end without a smooth transition in its power valves' operation. For his riding ability and that type of terrain, he struggled, feeling the bike didn't quite deliver the expected engine performance. But, he did like its suspension, especially the front-end feel, which provided good feedback from the rear wheel and front tire. A common point of contention was the TM's levers, particularly the brake and gear levers, which were described as very long. Skibbo mentioned struggling to get his foot positioned correctly for the rear brake on downhills because of the lever length. Riders noted they were often shifting using the lever arm itself rather than the pedal tip. There was a concern these long levers could easily get damaged in tough bush riding; it's tough enough out there without worrying about easily broken parts. The seat height also contributed to a distinct riding position. Briggsy echoed some of these sentiments. While he didn't mind the suspension too much and thought the chassis was okay, he felt the motor let the TM down. He called it a "light switch," with some bottom-end, more than the Fantic perhaps, but then "no mid, no top." This abrupt power delivery made it difficult to manage in slippery conditions where a wide range of smooth power is preferred. Todd, another tester, felt the TM still has its own distinct identity, perhaps feeling "a little bit more Euro" and slightly behind in the push for linear, rideable power that many other brands now offer. He even said it "feels 10 years older," suggesting it didn't feel as refined as other modern sport motorcycles in the cc dual sport motorcycles category. Skibbo strongly agreed, comparing it to his brother's 2008 TM which he remembered as a light switch bike, scary to ride. He found the ergos and switchgear a bit "funky." Despite its stunning looks – "a work of art," with "superb welding" and a well-sized fuel tank – he was ultimately disappointed with the riding experience. It was pointed out that the TM tested was the carbureted model, and a previously tested injected TM was a much better, more user-friendly bike. This highlighted the significant difference setup, including engine mapping and the type of power valves used, can make to how a bike feels. The French Competitor: Sherco 300 SE Factory Finally, the Sherco 300 SE Factory. Mitch, the narrator of the video, personally felt its suspension was probably the firmest of the group. He thought both it and the Beta felt the "raciest," but gave the edge to the Sherco for its firmer, stiffer suspension feel. This characteristic often appeals to riders tackling motocross bikes style jumps or high-speed sections. The se factory model comes well-equipped from the showroom. Jeff, considered one of the "racer boys," felt most comfortable on the Sherco. He liked the fork, describing it as "nice and plush" initially but "solid" when pushed hard. He noted you sit quite high on the bike, which might be a consideration regarding seat height for some riders. He found it strong, fast, with well-integrated components like its Selle Dalla Valle seat, making it easy to move around on. The seat grip was also a plus, similar to the KTM's, also often from Selle Dalla or similar quality. He concluded the Sherco is definitely aimed at racers, but felt the Austrian bikes, particularly KTM and Husqvarna with their closed-chamber forks, are bridging that gap. They offer rideability but can still be pushed hard; even on a challenging flatland jump, the Sherco handled it well, showcasing its robust rear suspension. Graham, who is taller, liked the Sherco. He felt more "away from the seat" compared to other bikes, which suited his height. He found the bottom-end power "really nice and easy to use," making technical stuff easier to manage. Skibbo agreed, calling the bottom-end "really, really, really strong and really user-friendly." He also praised its clean jetting, effective hydraulic clutch, comfortable ergonomics, and well-functioning electric starting system. For him, it was "by far the best Sherco I've ridden." Key Takeaways from the Testers It's clear from the riders' feedback that there isn't one single "best" bike. Each machine in this 300cc two-stroke shootout has its own personality and strengths. What works for one rider might not be ideal for another, especially as skill level varies. It often comes down to riding style, typical terrain, and personal preference for how an off-road bike should perform. The Fantic XE300 made a strong debut with its injected engine feeling surprisingly close to a carb model, though its bottom-end power was a slight concern for some. The Beta RR300 Racing, or rr race, lived up to its champion status, proving to be fast, race-ready, and possessing an excellently tuned carburetor setup that many riders loved; the performance from its KYB suspension was a highlight. The KTM was often highlighted as a superb all-rounder, especially with its improved TBI system and balanced chassis; its electric start is flawless. For general dirt bike riding and reviews, bikes like the KTM often score well across a wide range of abilities. The Sherco 300 SE Factory impressed with its race-focused feel, strong yet user-friendly engine, and comfortable ergonomics for aggressive riding. The TM300EN stood out for its beautiful craftsmanship but presented a more challenging, old-school power delivery that wasn't for everyone; some testers didn't feel it matched modern expectations. The GasGas EC offered a good entry point for trail riding, particularly at slower speeds, though it would need some accessories like a skid plate. And the Husqvarna TE 250, despite its smaller capacity, showed it could hang with the 300s, particularly with its pleasant bottom-end power, showing that not all cc dual sport machines need to be big bore to be fun. One thing Geoffrey mentioned really hits home: ten years ago, picking between bikes was easier. Now, he'd "happily own every one of these bikes." The quality and performance across the board have become incredibly high, and many feature niceties like oil injection and reliable electric starting systems. We truly are splitting hairs when comparing modern enduro bikes, even down to the performance of the rear wheel traction. Small differences in suspension feel, engine character from power valves, or ergonomics can sway a rider's preference, but all these machines are highly capable. Choosing often comes down to very specific needs and what a rider prioritizes in their off-road motorcycle experience. Conclusion This detailed look into the 2025 300cc two-stroke enduro bikes, thanks to the comprehensive testing by Australasian Dirt Bike Magazine, really shows the incredible diversity and capability available to riders today. Whether you're chasing podiums, exploring technical trails requiring good low-end power, or just love the thrill of a potent two-stroke, there's a bike in this lineup that could be your perfect match. This particular 300cc two-stroke shootout helps clarify what each model, from the Gas Gas to the Sherco se factory, brings to the dirt. Remember that test riding, if possible, is always the best way to find the bike that truly connects with you and your individual skill level. Happy trails.
