PDF Manuals is an independent motorcycle maintenance reference run by a small team of riders and home mechanics. It started the way most garage projects do: we were tired of digging through forum threads and dead links just to find one number — how much oil an engine takes, what pressure the tires want, when the next service is due.
The mission is simple. Every maintenance value on this site — oil capacity, tire pressure, service intervals, torque figures — is published with a source you can check yourself. That source is usually the manufacturer’s own service or owner’s manual, or an official brand portal. Where we can, we point you to the official manual as well, so you can read the full document rather than trust our summary.
The site currently covers more than 3,300 models from over 100 brands, and the library keeps growing. We are reader-first: no accounts, no paywalls, no email required to look up a number.
Questions, remarks or a manual we are missing? The contact page has the details, and we are genuinely happy to hear from people who work on their own bikes.
