Working on the ST2 requires precise tolerances. The documentation outlines exact factory clearances, including the intake valve clearance (0.05–0.12 mm), maximum rear brake disc distortion (0.3 mm), and the 3.5-liter coolant system capacity. You will find complete teardown sequences and torque tables to guide heavy internal engine work or routine fluid replacements across the Brembo hydraulic circuit.
Because working on high-performance motorcycle systems involves significant mechanical risks, always ensure you are familiar with proper shop safety practices or consult a certified technician before applying these factory specifications to your machine.
