RTX-0 Super Builder Platform
A builder-focused 1000cc-class crosskart platform for fabricators who want maximum control.
Starting At
$75
Digital Plans Download
Physical chassis options start at $2,199.
Built for Fabricators Who Want Full Control.
The RTX-0 Super Builder Platform is designed for experienced builders, fabrication shops, and race teams that want to control more of the build process themselves. Instead of forcing customers into a pre-assembled package, RTX-0 gives builders access to digital plans, chassis options, and supporting parts.
This is the right platform for customers who have welding, fabrication, and race vehicle assembly experience. If you want a pre-assembled roller or complete race vehicle, the FX750, FX10R, or RTX-T platforms are the better fit.
Digital Plans Available
Start with downloadable build plans for experienced fabricators who want to cut, weld, and assemble their own chassis.
Builder Chassis Options
Choose from unwelded, welded, or welded-with-mounts chassis options depending on your fabrication capability.
Maximum Customization
RTX-0 gives builders more freedom to source, fabricate, and configure the final vehicle their own way.
Choose Your RTX-0 Builder Option
The RTX-0 is a kit-only builder platform. It does not offer Roller, Race Roller, or Complete Race Vehicle packages. Builders can start with digital plans or select a physical chassis option, then add components through the RiskTaker parts catalog as needed.
