Crosskart questions
Which engine fits the FX1000?
Chain-driven motorcycle engines with an internal sequential gearbox, up to 180 hp and 120 Nm. For a first build we advise a 600 cc fuel-injected engine with 100–140 hp.
What skills and tools do I need?
Reading technical drawings and welding: MIG/MAG for the frame and A-arms, TIG for small parts. You cut and bend tubes or buy them bent, and need a small press and a heat source for the bearings.
How long does a first build take?
Not two weekends, but not years either. With one evening a week and a Saturday now and then, most builders finish within a year. Our build guide explains how to plan it.
Is the FX1000 road legal or approved for racing?
No. The FX1000 is an off-road vehicle for private grounds and tracks. It is not road legal and not homologated for racing.
Can I buy part of it and make the rest?
Yes. Every module has its own plan, laser files and kit, and the part numbers in the plan match our shop. Mix as you like.
Do you ship to the US and Canada?
Plans and laser files: yes, as an instant download. Physical parts and kits are not shipped to the US and Canada.
