2024 GasGas EX 250 Technical Information

Features and specifications of GasGas’ 250 two-stroke cross-country racer.

GasGas dipped its toe in the two-stroke cross-country motorcycle market in its first year under KTM ownership with the EX 300 in 2021. The following year, it introduced a second front number plate–equipped off-road two-stroke model in the form of the EX 250. This quarter-liter smoker has a 5.6mm smaller bore than the EX 300 but they share much else in common, including the fact that they’re completely revamped for 2024, as is the rest of GasGas’ cross-country range as well along with the full-size motocross, enduro, and dual sport lineup. Before releasing our test of the EX 250, we’ve compiled a stack of static and detail photos to examine some of what makes it unique and technologically advanced.

GasGas’ EX 250 hit the market in 2022 and was unchanged mechanically for 2023, but that’s certainly not the case for its third year on the market. The fun Austrian brand’s 250 two-stroke cross-country model is all-new in 2024.Jeff Allen
Two major updates to the liquid-cooled two-stroke 249cc single-cylinder engine are that it’s fuel-injected via throttle body injection (TBI) and features an electronic power valve.Jeff Allen
Throttle body is a Keihin 39mm.Jeff Allen
On our in-house Dynojet 250i rear-wheel dynamometer, the EX 250 churns out peak figures of 43.2 hp and 29.0 lb.-ft. of torque.Jeff Allen
Header pipe is shaped for maximum ground clearance.Jeff Allen
Silencer is shorter than it’s been in years past, follows lines of the bodywork nicely, and isn’t finished in black like the KTM 250 XC’s is.Jeff Allen
A larger-capacity fuel tank than a motocross bike is a key trait of nearly all cross-country models. GasGas’ entire EX range holds 2.4 gallons.Jeff Allen
Like the fun Austrian brand’s enduros and dual sports, its off-road competition models use a gas cap with a button to release it.Jeff Allen
Radiator cap is new for 2024, but remains 1.8-bar.Jeff Allen
Another change for MY24 is the switch from Brembo to Braktec for the hydraulic clutch system.Jeff Allen
Engine start and stop buttons are now combined on a single module within thumb’s reach on the Neken handlebar’s right side.Jeff Allen
One of the cost-saving measures GasGas uses to keep the MSRP of its cross-country racers lower than that of KTM’s and Husqvarna’s is forgoing a combination switch, which, on the premix-burners, features two engine maps. It can be purchased through GasGas Technical Accessories and installed on the bike (part No. A44039974044).Jeff Allen
While the 2021–2023 GasGas motocross and off-road competition models didn’t come with an hourmeter in stock trim, the 2024 models do.Jeff Allen
Air forks are a thing of the past on GasGas’ EX range. Say hello to the WP Xact 48mm closed-cartridge coil-spring fork.Jeff Allen
Although shorter, the WP Xact shock’s travel remains 11.8 inches.Jeff Allen
Shock spring rate is 45 Nm.Jeff Allen
You can leave the flat-blade screwdriver and 17mm T-handle in your toolbox. The EX 250’s shock damping adjusters are movable by hand in 2024 and beyond.Jeff Allen
Swingarm is slightly stiffer and lighter weight than the previous-generation (2021–2023) models’.Jeff Allen
With high speed in mind, gearing is 14/49.Jeff Allen
Triple clamps are made of forged aluminum like the prior generation, but feature a new design.Jeff Allen
Brake systems have also been swapped from Brembo to Braktec.Jeff Allen
New handlebar mounts are adjustable and have a slightly larger contact area against the bar to lessen the chances of it twisting in the event of a fall.Jeff Allen
In addition to being larger, footpegs are mounted further inward on the frame to make them less prone to catching edges of deep ruts and jump takeoffs.Jeff Allen
ODI lock-on grips are a staple on all Austrian-built dirt bikes.Jeff Allen
GasGas shaped the latest-generation radiator shrouds in a way that helps riders grip the bike better.Jeff Allen
The entire bodywork package is new, including the front fender.Jeff Allen
The EX 250 and EX 300 look practically identical. One way to tell them apart is by the model name sticker.Jeff Allen
GasGas’ 250 two-stroke cross-country racer hits the Dirt Rider automotive scales at 242 pounds wet.Jeff Allen
