Fantic’s XEF 310, is an exciting blend of agility and power, sitting perfectly between the nimble 250 4T and the torquey 450 4T. Designed with extensive development to balance performance and rideability, this bike offers a smooth yet powerful experience that many riders claim makes it nearly impossible to go back to a smaller or larger displacement.
First Impressions
Swing a leg over the XEF 310, and the immediate feeling is confidence-inspiring. The lightweight aluminum perimeter frame and well-balanced chassis make for effortless maneuverability, whether you’re tackling technical trails or open fire roads. With a seat height of 955mm, it’s slightly tall but expected for an enduro machine, ensuring good ground clearance while maintaining control.
Engine & Power Delivery
At the heart of the Fantic XEF 310 is a 304cc, single-cylinder, 4-stroke DOHC engine with a 12.8:1 compression ratio. This provides a smooth and manageable power curve, eliminating the intimidation factor that can sometimes come with high-strung, larger-displacement enduro bikes.
One of the standout features is the three engine maps – Hard, Soft, and Standard – switchable on the fly via handlebar-mounted controls. This allows riders to tailor power delivery based on terrain and skill level. The addition of a 9-level traction control system further enhances adaptability, making the bike as capable in slippery, muddy conditions as it is on hard-packed dirt.
Even in the Soft mode, the bike feels responsive and eager, while the Hard setting unleashes the full potential of the 310, making it a serious contender for riders looking for race-ready performance.
Technology & Connectivity
One of the most innovative aspects of the XEF 310 is its integrated WiFi system, allowing riders to adjust engine settings via a smartphone app—a feature borrowed from Yamaha’s advanced tuning technology. This means you can fine-tune power delivery, traction control, and throttle response without plugging into a laptop or ECU.
Suspension & Handling
The fully adjustable KYB 48mm front forks and KYB rear shock offer 310mm and 317mm of wheel travel, respectively. This means superb absorption of bumps, jumps, and rocky terrain while still feeling precise and controlled at high speeds. The aluminum swingarm with progressive linkage adds to the stability, ensuring predictable handling even in aggressive riding conditions.
With a wheelbase of 1480mm, the XEF 310 strikes an ideal balance between agility in tight sections and stability at speed. Whether you’re navigating steep inclines, rutted-out trails, or high-speed fire roads, the bike stays composed and planted.
Braking & Traction
Stopping power is delivered via hydraulic disc brakes with a 270mm front rotor and a 245mm rear rotor. This setup ensures consistent and reliable braking performance, even in demanding conditions. The 90/90×21 front and 140/90×18 rear tire combination provides excellent grip on a variety of surfaces, further complemented by the bike’s 9-level traction control for enhanced confidence.
Weight & Fuel Capacity
At 106 kg (kerb weight), the Fantic XEF 310 is remarkably light for a mid-sized enduro machine. This low weight translates to exceptional maneuverability and reduced rider fatigue, particularly during long rides or technical terrain.
With a 7.9-liter fuel tank, the bike offers decent range for enduro riding, though aggressive throttle use in higher engine modes may shorten ride time between refuels.
The connection between Yamaha and Fantic
Yamaha Motor Europe and Fantic Motor have a strong strategic partnership, which was significantly reinforced in 2020 when Yamaha announced the transfer of its subsidiary, Motori Minarelli, to Fantic. This acquisition, completed in January 2021, allowed Fantic to expand its expertise in engine technology, particularly in e-mobility and high-performance motorcycle engines. Fantic has since integrated Minarelli’s advanced engineering to enhance its range of off-road, enduro, and motocross bikes, equipping them with reliable, high-performance engines. Many of Fantic’s motorcycles now feature upgraded versions of Yamaha-derived engines, fine-tuned for power and efficiency. The partnership benefits both companies, as Fantic gains access to advanced engine production capabilities, while Yamaha ensures continued collaboration in the development of two-wheeled vehicles. This alliance strengthens Fantic’s market position and enhances innovation, particularly in the off-road and e-mobility sectors, leveraging Yamaha’s extensive manufacturing expertise and global presence.
Final Verdict: Is the XEF 310 Worth It?
For riders looking for the perfect middle ground between a lightweight 250 4T and a high-powered 450 4T, the Fantic XEF 310 is an exceptional choice. It delivers a powerful yet manageable riding experience, bolstered by advanced electronic features, customizable power modes, and top-tier suspension.
Whether you’re an experienced enduro competitor or a weekend trail enthusiast, the XEF 310 offers a level of versatility and confidence that few bikes in its class can match. If you’ve ridden one, you probably understand why many say, “once you go 310, there’s no going back.”
