Check my bike
Pick your bike and check it job by job. Oil gets a plain verdict on any bottle — safe, conditional, or no — against what your manual actually asks for. Brake pads get their shapes and the compound ladder; brake fluid, coolant and chain get the spec, straight from the sourced sheet.

Every fact wears its receipt
Every number on the site wears its receipt. Each fact carries a confidence tier, the source it came from with a page or part reference, the date we last checked it, and a flag when sources disagree. Click a citation and you land on the manual or catalogue it came from.
- OEM-verified — Straight from the owner's manual or a manufacturer registry.
- Cross-referenced — Two independent catalogues or a manufacturer parts page agree.
- Community — Widely reported and plausible, but no primary source yet.
- Unverified — A known gap. Shown in the open, never guessed at.
