XEF 450

A bike for the most ambitious: 450 is the queen of Enduro, the very limit between balance, control and overkill. But don’t worry: the XEF450 is a master of the art, with the 55-plus hp of the 4-stroke engine kept under control by 100% Fantic-made engine management.

If you’re looking for maximum adrenaline and performance, this is the bike for you.


Our fabulous 4-stroke requires no introduction: an engine with great power and everything it takes to enjoy it – badass when needed, but always manageable.

Characteristics that arise from a series of solid solutions like the double cam shaft and drive shaft, and a touch of craziness.

The inverted head, combined with a backwards-sloping cylinder, centralises the weight and guarantees exceptional agility and impressive handling.


The exhaust system is an essential component to get the best from our 4-stroke.

Developed in collaboration with Arrow, the manifold closely hugs the cylinder to centralise weight, while the aluminium terminal releases all the power and thrilling sound of a 450.


A rider becomes a winner if his performance is consistent from start to finish.

The 8-litre central tanks allowed us to work with the Enduro Factory Team on an ergonomic design that’s sleek, clean and contoured.

The seat design is also key, comfortable and with great grip. And all to offer you maximum comfort and freedom, from a Sunday ride to a 6-day event.


Want to turn on a sixpence? Want to correct your course at the last moment to avoid an obstacle?

Our superb aluminium frame was designed for this.

Moulded, extruded and die-cast components join forces to guarantee the ideal balance of lightness and rigidity, agility and precision.

High quality suspension should guarantee ultra-precise handling, using every millimetre of the stroke to filter the terrain and keep only what the rider needs.

This is why we chose KYB and a 48 mm pressurised closed-cartridge SSS (Speed Sensitive System) fork, with 300 mm of travel and super-adjustable for preload, extension and compression.

The mono shock absorber is also Kayaba, with 315mm wheel travel.


With the dedicated WiGET app, it’s like having several bikes in one. With a simple click from your smartphone, the bike’s ECU adjusts to one of the mapping setups developed by Fantic Racing, or you can create your own engine setup, for any terrain and weather conditions.

It’s also possible to read the bike’s meter, add service notes, get diagnostics and view engine data in real-time.


Is there a discipline with more obstacles and pitfalls than Enduro?

We want you to tackle any course without worries, and that’s why the XEF450 comes with hand guards and a robust engine standard
