FX750 CrossKart
The lightweight crosskart platform for 600–750cc sport bike engines.
Starting At $2,499
Builder Chassis — Unwelded Kit
The FX750 is RiskTaker’s most accessible crosskart platform — compact, lightweight, and built for serious grassroots racing, rallycross, and track use.
Built for Agility. Designed to Win.
The FX750 CrossKart is the most accessible way to get into a purpose-built RiskTaker race platform. It is designed around 600–750cc sport bike engines, 10-inch beadlock wheels, and a compact chassis that keeps weight down and response sharp.
This platform is ideal for first-time crosskart builders, grassroots racers, small teams, and experienced fabricators who want a lightweight competition vehicle with lower operating costs than larger 1000cc-class platforms.
