Keep An Eye On Fluid Leaks

A tiny mark under the bike can be nothing, or it can be the first sign of a job waiting to happen. The important thing is not to ignore it blindly.

Work out what the fluid is, where it came from, and whether it keeps appearing. Oil, coolant, brake fluid, fuel, fork oil, and chain fling all have different meanings. Some are urgent. Some are messy but harmless. Guessing is not diagnosis.

If the bike is leaving spots, investigate. Clean bikes make this much easier.
