All the finest engineering and craftsmanship has gone into the concept, design, creation, and finishing of FX Engines. This engine and all of its parts were designed and manufactured by FX in-house in Slovakia, Europe using all the finest European materials and the most advanced Swiss, German, and Italian technologies. Even the crankcase was die cast in-house using fully robotic die casting technology.

All parts are individually measured and inspected, and dimensions of all parts are recorded to ensure a full manufacturing & assembly record of every single part. Each engine includes a manufacturing certificate that records all the important serial numbers and measurements so that, at any time, all details of the production – including material batch, machine programs, responsible craft persons and production dates – can be traced back to its roots.
