Check RappelConso (motorcycles & scooters) →⚠️ This tool helps you understand what's going on with your motorcycle; it doesn't replace the inspection or judgment of a certified mechanic. If in persistent doubt, if a safety-critical part is involved (braking, steering, bearings, transmission), or if the problem keeps recurring, have the diagnosis confirmed at a workshop before doing any work.
