The perfect balance, XEF310 is positioned in an already wide range right between 250 and 450, and boasts the perfect balance of the best features of these models. In fact, the extreme agility, ease of use and consequent riding fun of the 250 4-stroke is guaranteed, but with a powerful power delivery and torque that comes close to its big sister 450. Many hours were spent searching for precisely the best balance between performance and ease of use even for the amateur.

ENGINE
The 304cc has been developed specifically for enduro use: this has resulted in a compression ratio (12.8) that is not too steep, but much more suitable for all-round off-roading.
Lots of torque in the low range, with a full and enjoyable delivery at all revs without losing power in the highs and without the sometimes excessive nastiness and explosiveness of many 450s.
MAPS AND TRACTION
The character of the engine is customisable and even more refined thanks to new engine maps with refined engine brake management: you can choose one of 3 dedicated mappings (hard/soft/standard), directly from the handlebar-mounted Multiswitch. From the same instrument you can also control traction control on 10 levels.
CHASSIS
Like its 250 and 450 sisters, it boasts a chassis compartment that is unrivalled in the enduro scene. Forged, extruded and stamped parts combine to give you the ultimate balance of lightness and stiffness, agility and precision.
A quality suspension must ensure super-precise handling, using every mm of travel to filter the terrain and return only what the rider needs
That’s why we chose KYB using a 48mm pressurised closed-cartridge, 300mm travel, ultra-adjustable SSS (Speed Sensitive System) fork with adjustable preload, rebound and compression damping.
The monoshock is also Kayaba, with 315mm of wheel travel. The brake discs are 270mm at the front and 245mm at the rear.
WIFICOM E APP WIGET
Also standard is the WIFI COM, which contributes to a complete electronic package to tailor the motorbike to you. And thanks to the dedicated ‘WiGET’ app, it’s like having several motorbikes in one.
With a simple click on your smartphone, the bike’s ECU can be set to one of the maps developed by Fantic Racing, or you can create your own ideal engine setup for all types of terrain and environmental conditions.
You can also read the bike’s hour meter, add service notes, read diagnostics and view engine data in real time.
