I have always been a fan of trials riding and have done it on more than a few occasions. When my son Aden first started to learn how to ride I put him on a trials bike, just so he could get the feel of balancing a motorcycle, weighting the footpegs as well as use the brakes properly. As motocross or off-road riders we have a tendency to try to rush through sections in order to get to the checkered flag first, but with trials riding it’s the exact opposite. While we are under some weird times in our country right now with the pandemic I wanted to be able to get outside, but also try to be a little safer while getting my two-wheel fix in. Trials riding is a much safer two wheeled sport than motocross, but it still can give you those butterflies in your stomach when you have to go up and over a rock that you may think is not possible.
Aden and I spent hours on some rocks near my home in Hesperia, California as well as created some make shift courses around our backyard, without disturbing our neighbors. Getting to ride with my son side by side while still being able to laugh and talk to him is priceless. Not to mention being able to teach him proper balancing technique as well as open his creative mind to possible new obstacles only helps his motocross riding. Riding trials can also break up the monotony of just doing lap after lap of motocross riding and can keep that fire burning maybe once he’s done riding moto. I have ridden motocross/off-road for so long it’s actually really fun to suck at something so badly. Riding trials is one of the most fun two wheeled sports that you may have never tried. I am not going to sit here and write you up an article on the ins and outs of the GAS GAS TXT Racing 250 machine like I can a motocross bike, but below is a breakdown of the highlights of the new GAS GAS trials machine. Stay tuned for a podcast about the GAS GAS TXT Racing 250 Trials Machine over on keeferinctesting.com and maybe we can get Matthes on this sucker and get his thoughts.
Riding a trials bike will feel very funny to most dirt bike enthusiasts when hopping on one. The GAS GAS TXT 250 is very roomy, feels light at around 148 pounds dry, has a very responsive engine character and suspension that allows you to hit some fairly big obstacles in stock form. Since I am a novice type trials guy I left the Gas Gas in second gear on most of my obstacle attempts in order to tone down the responsiveness that it has. You would think that you would have more tire spin on slick rock, but the Michelin’s hook up very well, so for beginner’s I would recommend staying in a higher gear when you’re learning to get over an obstacle. Starting the Gas Gas is a little tricky so be ready to give it a good kick even though the kickstarter itself is not very long. I tried the two engine modes that the GAS GAS comes with but preferred the standard mode was best under dry rock conditions.
- The GAS GAS TXT RACING 250 brings the perfect balance between fun, usable 2-stroke torque and power and nimble, lightweight handling. It shines in tough, technical terrain thanks to the high-revving engine’s punchy yet manageable power delivery. Combined with class leading suspension, selectable engine maps and

- 2-stroke single-cylinder liquid cooled 250 cc engine (247.7 cc) features the latest 2-stroke technology and is designed to be powerful, light and compact. The cylinder features thermodynamic ports, which contribute massively to power figures and make the engine the most competitive 250cc 2-stroke in its class.
- Cast aluminum cylinder head domes have been designed to improve combustion and obtain the best engine performance.
- Cylinder with a 72.5 mm bore and specially designed intake and exhaust ports provide excellent torque and power delivery. The low weight aluminum cylinder bracket reduces engine vibrations and stiffens the structure with the chassis. The piston is specially developed using high-performance forging and coating for increased power, responsiveness and durability.
- The crankshaft delivers a 60 mm stroke that produces optimal torque and revs. It is ideally balanced and designed to obtain the maximum inertia with the minimum weight as well as being positioned to centralize mass, contributing to better handling. A closed main bearing made by SKF increases durability and reduces the amount of lubrication needed.
- The crankcase is manufactured using a gravity casting production process to help with weight reduction while retaining strength and durability. The compact design provides an ideal center of gravity for perfect motorcycle movement. To make the engine more compact, the clutch cover includes the clutch master cylinder.
- Chrome-moly (25CrMo4) steel tubular frame is expertly crafted using 1.5 mm tubes, laser cutting and robot welding, and is developed using specifically calculated parameters of longitudinal and torsional flex. The frame weighs a total of 6 kg (13.2 lbs) and is finished off with a durable red powder coating.
- Hollow one-piece cast aluminum swingarm offers optimal stiffness and reliability at the lightest possible weight and performs with perfect flex behavior. A redesign of the swingarm and linkage give a new progressiveness to the new GASGAS TXT RACING 2020 range, increasing stability and improving traction.
- Adjustable TECH 39 mm front forks provide 180 mm of travel and an exceptionally smooth and progressive ride. The left side fork has a progressive adjustable spring, as well as an “End Stroke“adjustment function in order to avoid bottoming. The right side fork is fitted with the rebound adjustment clickers at the top.
- ÖHLINS 2-way hydraulic rear shock absorber with 174 mm of travel brings top performance and comfort and provides maximum traction to the rear end. With adjustable damping you can change the behavior of the shock to suit your taste by setting the spring preload and rebound adjuster clickers.
- CNC machined black-anodized aluminum triple clamps with 35 mm offset provides a secure fork mount for precise handling.
- The GASGAS 1/3 compact clutch, consisting of three Kevlar friction plates + two steel plates with a Belleville spring system, with adjustable clutch pre-load system to improve power and torque delivery and BRAKTEC hydraulics deliver the maximum torque with a light and easy feel, near maintenance-free operation and perfect modulation in every condition. Clutch play is constantly compensated so that the pressure point and function of the clutch remain identical in cold or hot conditions, as well as over time.
- BRAKTEC braking system offers the highest level of braking performance while being specifically tailored for trial riding, delivering a sensitive and modulated feel. The front monoblock 4 piston caliper with 185 mm front waved floating brake disc by NG and the rear 2 piston 150 mm caliper with its 150 mm NG waved disc keep weight to a minimum and offer complete braking confidence.
