Specification Highlights

Factory data leaves no room for error when rebuilding these classic in-line fours. Engine compression pressure sits at 1176.8±98.1 kPa for the CBX400F and 1225.8±147.2 kPa for the CBX550F. When setting up the valvetrain, the intake valve clearance for the 550 requires a precise 0.10–0.14 mm gap. Down in the bottom end, lubrication data dictates a CBX400F oil pressure of 490.3 kPa at 7,000 min⁻¹. The 6-speed constant-mesh transmission utilizes a primary reduction ratio of 2.565.

Please note that this document serves strictly as a technical reference for workshop environments. Always consult a certified motorcycle technician before performing service on high-pressure engine systems or chassis components to ensure complete operational safety.
