GasGas Launches New RX 450F Replica Rally Bike

The Spanish brand releases a customer version of its Dakar-winning machine.

Last week we reported that a Rally Replica bike from GasGas was likely coming based on recently-filed type approval records. And now, it’s official – the Spanish brand has just announced the worldwide launch of a limited-edition Rally machine that is as close as it gets to a true factory bike. Dubbed the RX 450F Replica, the model is a pure race-breed machine designed to excel in and win multistage cross-country rallies.

Using feedback from Sam Sunderland during the design process, the RX 450F is equipped with a long list of high-spec rally-specific components and has the same gear ratios Sam used to win the 2022 Dakar Rally.

Each replica bike is assembled by hand with many of the very same high-performance components that can be found on Sam Sunderland’s Dakar-winning machine. Using feedback from the Dakar champ during the design process, GasGas explains the bodywork features race-specific ergonomics with “essential rider-bike contact points in all the right places allowing riders to grip the bike with minimal effort.” An ultra-light carbon fiber navigation tower behind the front fairing further helps reduce neck strain at high speeds.

The bike is equipped with an XPLOR PRO 7750 shock at the rear. The integrated TRAX system knows when the rear wheel loses touch with the ground on rough terrain and opens an oil bypass to rebound faster and push the rear tire into the terrain offering maximum traction.

Based on the powerhouse motor from the brand’s MC 450F motocross bike, the GasGas RX 450F Replica tames things just a little with electrical wizardry to deliver usable power tailored specifically for rally racing. For added reliability, there’s a strengthened clutch and gearbox, a reworked SOHC cylinder head, as well as a Pankl con-rod and piston. 


One of the key components that makes the GasGas RX 450F Replica bike outstanding is the Engine Management System (EMS). One of its clever features is that it activates a tailored engine map for each gear, which means maximum power is transferred to the rear wheel in higher gears, while in low speed, low gear situations, a broader spread of power is delivered for total control when things get technical.

The Replica bike also features some of the best suspension that money can buy – WP XPLOR PRO 7548 forks up front with the XPLOR PRO 7750 shock at the rear. “This combo inspires confidence thanks to its consistent performance across the roughest and toughest of rally terrain,” says GasGas.

Completing the build and making sure that the GasGas RX 450F is capable of racing at the highest level from new, a selection of the finest aftermarket components are installed during the assembly process. We’re talking X-TRIG triple clamps, oversize Brembo brakes, an Akrapovic exhaust, a Supersprox Stealth sprocket, Neken bars, a GasGas branded Hinson Clutch cover and more.

GasGas has stated that the RX 450F is available through dealerships worldwide in very limited numbers. No specific details about pricing or the number of available units were given by the company but we expect it to be positioned similarly to KTM’s Rally Replica bike, which is restricted to around 70 units and costs about €25,900 ($27,220 USD). 

For more  information, contact your national GASGAS dealer or importer.

I have one I’ll sell you but it is not a replica. It was Skylar Howles race bike.
