How this works

Pick your bike, where the problem is, and what you notice. The tool lists the 287 problems in this guide, sorted by system.
Each answer opens a full diagnosis: is it safe to ride, two-minute checks, then yes/no steps that end at a repair, a part or a workshop.
Brakes, steering, tyres, fuel leaks and high-voltage faults are marked Do not ride or Stop now. Fix them before riding.
