Manufacturers and official manuals
Model specifications, capacities, dimensions, tire sizes, service information and official product details.
Where the data comes from.
The source should match the claim. A motorcycle manual is useful for specifications; a current retailer page is useful for an asking price; neither automatically proves accessory compatibility.
Official stores and identifiable Philippine retailers
Observed product pricing, current variants, availability and seller-specific offer information.
Established publications and archived launch records
Launch prices, discontinued generations and older information that may no longer appear on current manufacturer pages.
Marketplaces, forum posts and user claims
These can point to something worth checking, but they are not enough on their own for a technical specification or fitment claim.
Open the source
Motorcycle and product pages link to the source used for important changing facts whenever one is available.
