Model Description


The new GASGAS TXT GP range features an extensive list of premium components and performance upgrades. Using the knowledge gained from 15 successful FIM Trial World Championship campaigns, GASGAS Motorcycles has designed each machine to deliver uncompromised performance. Available in four capacities – 300cc, 280cc, 250cc and 125cc – each TXT GP model benefits from fully-adjustable, premium suspension, a carbon fibRe airbox, factory racing graphics and many other technical highlights. As GASGAS’ Factory edition, flagship trial models all TXT GP machines utilise parts developed and used on the official GASGAS Factory Racing machine of Jorge Casales.
All GASGAS TXT GP machines are built to excel at the highest levels of competition, designed for riders who expect nothing but the very best. Delivering optimised performance and reduced weight, the TECH GOLD forks and REIGER 3-way hydraulic rear shock ensure the TXT GP range delivers exceptional handling. Key engine modifications, including an S3 cylinder head, closed core ignition coil and titanium exhaust, provide the advanced power curve needed for top-level riders to scale the toughest sections. 
All GASGAS TXT GP models are fitted with carbon fiber airboxes, ensuring reduced weight as well as increased strength and a true factory look. In addition, Renthal handlebars and grips, CNC machined triple clamps, S3 footrests, an Aluminum front wheel axle, a titanium expansion chamber and optimised engine casings all deliver key improvements that ensure improved rideability, braking and strength. Finished with factory racing graphics all TXT GP models offer both optimised performance and true factory styling. 
New for MY22, the full TXT GP range rolls off the production line fully EURO 5 compliant.

TXT GP 250 2022


The classic motor displacement of the GASGAS trial range, the TXT GP 250 ensures the perfect balance between usable 2-stroke torque and nimble handling. Fitted with selectable engine maps, Braktec hydraulic clutch and brakes, class leading suspension, a titanium exhaust and much more, the TXT GP 250 delivers day-long fun. And thanks to the fact it revs to 10,500 rpm, the 250cc 2-stroke is versatile and leads the way in tough, technical terrain thanks to its strong, manageable power.
A piece of art and an industrial design masterpiece! The carbon fiber airbox fitted to the TXT GP line-up ensures maximum airflow and the best filter protection. Featuring a clever, patented design, the airbox is a structural part of each bike yet feature no additional sub-assemblies. The Twin Air filter is easily accessed and can be removed by taking out just one bolt.
Red (we like red!) CNC machined triple clamps help deliver a super stable front-end on all TXT GP models, and look great, too. Aiding overall handling and ensuring perfect fitting of the front forks, the 35mm offset clamps are made from the highest quality aluminum for ultimate reliability and minimal weight.
Similar to the TECH forks fitted to our TXT RACING models, just a little better… and golden! The 39mm Golden TECH forks feature 167mm of travel to ensure the entire TXT GP range offers the very best handling. A low friction coating on the stanchion tubes, combined with progressive rate springs and hydraulic compression and rebound adjustment ensure an incredibly smooth and stable ride. A 160 gram aluminum front axle guarantee riders have absolute front wheel confidence.
All our TXT GP models feature an S3 cylinder head. Forged from the highest quality aluminum, the two piece part increases compression and ensures perfect combustion for the very best engine performance. The cylinder head features cooling ducts to keep motor temperatures down.
Offering three different options, the adjustable, large platform Hard Rock pegs from S3 offer standard, forwards and backwards positioning options. Ensuring riders can fine-tune their bike depending on personal preference and riding conditions, they allow for a precise, individual set-up.
With the adjustability of compression and rebound as well as the spring preload the REIGER 3-way shock is one of the stand out features of all TXT GP models. Delivering serious performance, the REIGER shock ensures maximum traction, every time.
Finishing the look of our TXT GP models, a set of factory graphics gives each bike a clean, distinctive appearance.
