*Mid-displacement four-stroke front number plate–equipped off-road competition pre-owned bikes*
When it comes to off-road racing, especially in the cross-country and enduro disciplines, 350cc four-stroke dirt bikes have become one of the most desirable engine sizes for riders seeking the ideal balance between power and maneuverability. Whether you’re racing GNCC, WORCS, or just tackling challenging trails, the 350cc class delivers tractable torque, lighter handling than 450s, and more top-end punch than a 250F. For 2025, riders shopping the used market will find several excellent pre-owned models with front number plates—signaling their race-focused intent—still capable of competing or serving as high-performance trail bikes.
Here are some of the best used 350cc four-stroke cross-country bikes to look for in 2025:
—
### **1. KTM 350 XC-F (2022–2024)**
The KTM 350 XC-F is arguably the benchmark in the mid-size off-road competition category. Purpose-built for cross-country racing, it combines motocross-style aggression with the endurance of off-road tuning. With a lightweight chromoly steel frame, advanced WP XACT suspension, electric start, and fuel injection, the XC-F is a race-ready platform right off the showroom floor.
For used buyers in 2025, the 2022 to 2024 models offer excellent value. These years feature the updated engine architecture and chassis redesign that shaved weight and improved rider ergonomics. If you’re seeking a potent yet manageable used four-stroke with serious race pedigree, the KTM 350 XC-F should be high on your list.

### **2. Husqvarna FX 350 (2022–2024)**
The Husqvarna FX 350 is KTM’s close cousin, sharing much of its core technology while offering subtle differences in suspension feel and ergonomics. Husqvarna outfits the FX 350 with WP XACT air forks and a composite carbon-reinforced subframe, which contributes to a slightly different handling character—often considered a bit plusher and more stable at speed than the KTM.
The FX 350 is a popular choice for riders who want cutting-edge engineering with a slightly different aesthetic and feel. Models from 2022 and newer come with the same major platform upgrades as the KTM XC-F and are highly sought after on the used market.

### **3. GasGas EX 350F (2021–2024)**
Part of the Pierer Mobility Group alongside KTM and Husqvarna, GasGas entered the off-road competition scene with the EX line in 2021. The EX 350F is essentially a red KTM XC-F with slightly more basic components to hit a lower price point—think cast instead of billet triple clamps, and suspension with different valving. Yet the core frame, engine, and geometry remain top-notch.
Because it delivers much of the KTM performance at a reduced cost, the EX 350F is a smart buy for used shoppers in 2025. It also features a front number plate, no lights, and cross-country racing ergonomics, making it ideal for competitive off-road riding.

### **4. Beta 350 RR Race Edition (2021–2023)**
Beta may not be as dominant in the U.S. racing scene as the Austrian brands, but its 350 RR Race Edition is a legitimate contender for off-road competition. This Italian-built machine offers a more traditional suspension setup (KYB forks), nimble chassis, and strong low-to-mid power that’s especially well suited to tight trails and enduro-style terrain.
The Race Edition trims include upgrades like a quick-turn throttle, racing graphics, and weight-saving features. Although rarer on the used market, these Betas offer something unique and competitive for riders wanting a bike that stands out while still delivering proven performance.

### **5. Yamaha WR250F with a Big Bore Kit (Converted to 350cc)**
While not a stock 350cc, many riders looking for a unique project turn to Yamaha’s WR250F and install a 350cc big bore kit. The WR250F is known for its bulletproof reliability, strong chassis, and excellent KYB suspension. With a 350cc kit, it gains much-needed torque and power for more aggressive cross-country performance.
Buyers should carefully evaluate any modified machine, but if done correctly, a 350cc WR can be a great used option. Look for builds from reputable shops or experienced owners who’ve upgraded the ECU, fuel mapping, and internal components properly.

### Final Thoughts
In 2025, the used market for 350cc four-stroke cross-country bikes is rich with potential. These mid-displacement machines are popular for good reason—they offer a near-perfect blend of handling and horsepower for off-road racing and hard-core trail use. Whether you’re buying to compete or just want a high-performance ride with a front number plate and a competitive edge, these pre-owned models represent some of the best value and performance available.
Just remember: always check maintenance history, inspect wear on suspension and engine components, and verify that any modifications were done professionally. A well-maintained 350 can provide years of reliable, exhilarating riding.
