FX K301 EC - 3.5cc Off-Road Engine - 3 ports, DLC, Ceramic Bearing, Tungsten Balanced
The European Champion Engine K301 EC is based on the K301 engine but incorporates numerous improvements and refinements with focus on maximum bottom and top-end power.

The 3-port engine includes a ceramic bearing and diamond-coated crankshaft. The crankshaft is individually balanced with a tungsten weight and filled with silicone. The sleeve and piston set were specially selected and matched. The engine features 10-rib engine head.

Significant improvements were incorporated in the production & assembly processes, with new and even more precise quality inspection. All parts are individually measured and then specially selected and matched to increase engine reliability, performance, and quality.

All of the finest engineering and craftsmanship has gone into the concept, design, creation, and finishing of all FX Engines. This engine and all of its parts were designed and manufactured by FX in-house in Slovakia, Europe from the finest European materials and using 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 all dimensions are recorded to ensure a full manufacturing & assembly record of every single part. Each engine includes a manufacturing certificate that records all important serial numbers and measurements so that, at any time, all details of the production – material batch, machine programs, responsible craftsperson, and production dates – can be traced back to the beginning.
