The bike Honda should have built. Experience the raw, unadulterated power of a 500cc two-stroke integrated into the industry-leading geometry of the 2026 Honda CRF450R chassis. This isn't just a garage swap—it’s a professional-grade, turnkey machine designed for riders who demand factory-level execution and modern ergonomics.
Factory-Level Engineering
This build is as close as you can get today to a factory-level machine. At Two-Strokes Only, we approached this project with the same tools and principles Honda’s own R&D department would have utilized had the CR500 remained in production.
Using advanced CAD modeling, stress analysis, and mechanical engineering standards, we’ve ensured that the engine placement, frame geometry, and cooling efficiency meet the demands of whatever you may throw at it. Every bracket and CNC machined part is designed to feel like it rolled off the assembly line in Hamamatsu.
