EC 450F

The 2025 GasGas EC 450F brings big-bore four-stroke power to the enduro world with an agile character that belies its displacement. Fueled by an efficient Keihin EFI system and assisted by a responsive electric start, this machine surprises with nimble, tall-gear torque that rewards smooth inputs and confident control. Its all-red appearance, accented with durable in-mold graphics, sustains the Therm of factory feel while ensuring the bike looks sharp no matter how rugged the terrain. Built for trail riders who want smooth authority and enduro prowess in equal measure.​

 Power Meets Precision At the heart lies a potent 449.9 cc single-cylinder four-stroke engine with a 42 mm throttle body, generating controllable but exciting performance across the rev range. An electric starter and one-way DDS clutch featuring Braktec hydraulics make operation reliable and accessible, even on the roughest trails. The wide-ratio six-speed gearbox delivers the right gear for everything from tight switchbacks to open-speed sections, offering versatility that encourages full confidence from first ride to full-throttle attack.
Agile Chassis Performance The EC 450F impresses with handling that feels light and responsive like a smaller bike. Its central double-cradle steel frame, aluminum subframe, and lightened motor mounts offer stability without compromising agility. WP XPLOR front forks and a WP XACT rear shock—both with 300 mm of travel—deliver controlled damping and smooth feedback, while forged triple clamps and optimized steering geometry ensure precise control. Every detail combines to offer intuitive handling that keeps riders planted and pushing harder.
Trail-Ready Ergonomics & Utility With a 956 mm seat height and a dry weight of around 111 kg, the EC 450F remains accessible yet trail-capable, ideal for long rides and technical challenges alike. It features a transparent 9-liter tank for easy fuel checks, oversized footpegs that offer superior grip and mud clearance, and Neken handlebars with reinforced mounts to handle impacts. Maintenance is simpler, connections tighter, and control more intuitive—making this big-bore enduro a dependable companion for everything from weekend adventures to serious competition.
