advrider Posted February 28, 2022 Share Posted February 28, 2022 As Pierer Mobility’s latest motorcycle brand acquisition, GasGas wants to let everyone know it makes more than trials machines. In recent YouTube posts, the company is showing off two of its garage builds. From there, it builds two separate machines using factory parts available to the public. [embedded content] GasGas says that the primary goal of its flat tracker build was to see if it can build a legitimate flat track racer from a stock MC 450F motocross bike. To keep the build project simple (and show off its line of accessories), they tried to only fit “essential” GasGas technical accessories. However, they did mount one non-GasGas part—a complete Akropovic racing titanium Evolution Line exhaust system should free up some power and drop a bit of weight. Flat track build After taking off lots of parts, the rebuild process begins with a new WP Xplor Pro rear shock with shortened suspension travel. Next, the builders fit a new supermoto triple clamp to shorten the front of the bike’s suspension as well. The build continued with an WP Xact Pro fork and a slight gearing change, with 48-tooth black anodized rear sprocket. The bike’s tires and wheels were changed, for 19-inch flat track styled wheels shod with Maxxis DTR-1 tires. Although the video doesn’t give us the specs, it looks like at least the front rotor was changed, but with what, we don’t know. That said, it seems like the same Brembo calipers were re-attached. Since the bike would be charging hard into corners, GasGas fitted a slipper clutch to help eliminate rear wheel stamping under hard braking. The new clutch unit is protected with a new Hinson clutch cover. Flat track detail changes Next up was a minor change to the bike’s plastics; a shorter front fender was sourced from the company’s MC 85 bike, and once installed, the bike was ready to roll. For GasGas’s second garage build, they decided to convert another stock MC 450F motocross bike and make it into a supermoto machine. [embedded content] Supermoto build This time around, they followed a similar methodology by removing lots of the bike’s stock plastic and motocross-specific parts. Left with the frame and engine, GasGas first changed out the rear shock opting for a WP Xact rear shock with a shorter 266 mm of travel. Next up, the front fork; GasGas installed a supermoto triple clamp which they claim is “extra wide and CNC machined for optimal stiffness and clamping.” Then, the wrenchers added a handlebar support kit to give the handlebar new mounting points for better supermoto positioning. A new set of WP Xact forks legs were then inserted into the triple clamps. The forks also shortened suspension travel to 285 mm. To tighten things up at the bottom of the fork, an extended supermoto axle was added because of the wider triple clamps and front wheel rim. Now that the bike could roll, it was time to start thinking about what the machine needed to slow down. GasGas paired a Brembo monoblock caliper to a new 310 mm wave brake disc. Add a Brembo radial master cylinder for single-finger braking, and you’re off to the races. The converted GasGas supermoto. From there, the project saw stock wheels exchanged for a set of Alpina Supermoto wheels with a 16.5-inch front and a 17-inch hoop at the rear. Once again, since this bike would be charging hard into corners, a Suter slipper clutch was added to help eliminate rear-wheel hop under hard braking. Again, GasGas added a Hinson clutch cover and finished the project with complete Akrapovic titanium race exhaust system. Supermoto detail changes Down to the detail work: The nearly-complete supermoto machine received the same short fender from the GasGas MC 85 and a pair of its closed aluminum handguards to protect the bike’s levers in a fall. All in all, the videos are a good example of what can be done with a stock motorcycle to change its intended use and capability. Not bad for something that mostly came from the parts bin!
