Motorcycle, RV, Boat and Trailer Gear

Start with the vehicle type, then the system

This department is organized by vehicle first, then by system. Start with motorcycle and ATV parts for tires, batteries, controls, fairings and helmets; boating has its own gear, safety, engine and electronics sections; trailers have towing gear and components, and pilots have a section for headsets, flight controls and instruments. Choose the vehicle, then the make, model and year, because parts are often specific to one engine, hull, axle or tire size.

Plumbing, power and electronics repeat across vehicles

Several systems repeat across vehicle types, which is why similar parts turn up under different headings. Water systems use valves, fittings and drain parts with threaded, socket-weld or compression connections, so match the pipe size and thread to the existing plumbing; for caravans and motorhomes, start with RV parts and plumbing supplies. Batteries differ by chemistry and voltage, with 12 V the common level, and radios and displays have their own power and water-resistance ratings, so read each product's specification rather than the department name.

Questions about Motorcycle, RV, Boat and Trailer Gear

How do I know a part fits my boat, RV or bike?

Match the make, model and year, then check the physical specifications that carry over, such as thread size, bore, voltage, tire size or connector type. Where a listing names compatible models, rely on that over general descriptions, and compare the part number printed on the old part.

Is a marine part the same as an automotive one?

Often not. Marine parts are built for constant moisture and salt, using stainless steel, bronze or sealed electronics. An automotive part may corrode quickly on a boat, and electrical parts in gasoline engine spaces must be ignition-protected.

What should I check on a motorcycle or ATV battery?

Check the voltage first, usually 12 V, then the capacity in amp-hours, the physical size and the terminal layout. Lead-acid, AGM and lithium types differ in charging needs, so use a charger that suits the type.
