Motorcycle Parts

Wear parts, crash parts and whole engines:

three trades with very different buyers. Wear parts are what every bike eats through: the drive kit is the chain with both sprockets, front and rear, sold as a set because a new chain running on worn teeth wears out early. Brake pads and drum-brake shoes sit alongside it. Automatic scooters such as the Honda Navi have no chain; they wear out the drive belt and its rollers. Crash parts are the levers, mirrors and plastics lost in a slide on wet asphalt, and the big pieces come off bikes that have been written off or stripped. When fixing one would cost more than the bike is worth, look at motorcycles for sale, or step back to motorcycles.

Gravel roads and the badge on the tank:

between them they settle which part is right. A dual-sport bike like the Honda XR150L or Yamaha XTZ that lives on gravel wants a block-tread tire, which bites in loose stone and wears fast on asphalt, and an O-ring chain, whose sealed links hold their grease against dust and mud. Fork seals go early too, because grit on the tubes cuts the seal lip. The badge decides the rest. Honda, Yamaha and Suzuki parts come as original or aftermarket, and both are fair buys at their own price. Bajaj and Hero bikes come out of India, Serpento and Freedom from Chinese factories, and several share engine designs with other makes, so the part you need may be listed under another model’s name. Hold it against the old one before you trust the label. One cheap mistake costs a clutch: a geared bike needs JASO MA or MA2 oil, because its clutch runs in the engine oil. JASO MB is for automatic scooters, and car oil can make the clutch slip.

Cheap chain kits and hard-to-find tanks:

pull the used market in opposite directions. A plain chain kit for a 125 or 150 cc work bike is around ₡15,000 to ₡20,000 new, and an O-ring kit for a 250 to 400 cc bike runs about ₡30,000 to ₡45,000. With new wear parts that cheap, a half-worn chain or a tire with some tread left fetches very little. Used money sits in pieces that are dear or slow to get new, such as an undented tank or factory-colour plastics for a model no longer imported.

Sprocket teeth, belt cogs and tire sidewalls:

each shows a part’s age if you know where to look. Rear sprocket teeth that have turned pointed or hooked mean the whole kit is finished, and a chain you can pull away from the back of the rear sprocket is stretched. A drive belt with cracks across its cogs, or one visibly narrower than a new belt, is due. On a tire, check the tread against the wear bars in the grooves, look inside for plugs and read the date code on the sidewall: rubber that sat for years in a storeroom hardens and grips poorly even with full tread. Plastics give away repairs at the mounting tabs, where glue shows on the back, and a wheel should spin true. For an engine, hear it run, watch for blue smoke and ask for the documentation from the bike it left.

Part numbers, tooth counts and the model year:

belong in the title, because buyers search by their bike, not by the part. Say whether it is original or aftermarket, new or used. Photograph the tooth count stamped on each sprocket, the size moulded on a tire’s sidewall and every mounting tab on bodywork. If you are stripping a whole bike, one listing that names the model and the parts still on it saves a long thread of questions. Anyone travelling from Pérez Zeledón for a used engine will want to see it turn over, so keep it in the frame with a charged battery until it has gone.
