Tillotson Gen 2 Kart Racing Engine
The Tillotson 225RS is a Spec Class Racing Engine designed to elevate the performance of 4-cycle karting. In collaboration with our team at EC, Tillotson Racing designed an engine that would close the gap between 4-cycle and entry-level 2-cycle karting. The increased power output provides a more exciting and forgiving driving experience for novice and advanced drivers.
Based on the popular Honda GX200 architecture, the Tillotson 225R is familiar to most racers and kart shops, which can service the engines with less expensive and more accessible parts. Unlike the Honda or its many clones, the Tillotson 225RS is designed from the ground up to include a highly reinforced racing block to handle higher output and extended durability. Also, the redesigned "Non-Hemi" cylinder head with 27mm intake and 25mm exhaust is reinforced with more material between each fin for improved rigidity and cooling.
The Gen 2 features a higher rpm limit of 7500rpms, and the cylinder head has been decked to increase compression.
