Shop dirt motorcycle parts, spares and accessories for a wide range of motocross, enduro and off-road bikes at Radhouse. Explore engine components, brakes, chains and sprockets, suspension, replacement plastics, controls and essential maintenance parts, with UK delivery.
Dirt motorcycles are built for demanding conditions, from motocross tracks and enduro trails to recreational off-road riding. Keeping your bike in good condition means having access to reliable replacement parts, regular maintenance essentials and components suited to your specific make and model.
At Radhouse, we offer a wide selection of dirt motorcycle parts, spares and accessories for popular motocross and enduro bikes, including Yamaha, Honda, KTM, Kawasaki and Suzuki models.
Our catalogue covers everything from engine parts, pistons and gaskets to braking components, chains and drivetrain parts, suspension components, replacement bodywork and plastics and fuel, air and cooling system parts.
Whether you're carrying out routine servicing, rebuilding an engine, replacing damaged components after a ride or preparing your motorcycle for the next event, you can explore our range by parts category, manufacturer or motorcycle model.
Our Shop By Model finder uses make, model and year information where available to help you narrow down compatible products. This is especially useful for dirt bikes, where components can vary between different generations, engine sizes and motocross or enduro variants.
From everyday maintenance to more involved repairs, Radhouse makes it easier to find the parts you need to keep your dirt motorcycle ready for the next ride.
Always check the individual product specifications and compatibility information before ordering. If you're unsure which component is right for your bike, contact us and we'll be happy to help.
Use the Radhouse Bike finder to select your motorcycle's manufacturer, model and year. You can also browse our dirt motorcycle categories for engine parts, brakes, suspension, drivetrain components and replacement plastics. Always check the product compatibility details before ordering, as parts can differ between model years and engine variants.
Motocross bikes are generally designed for closed-course racing, while enduro motorcycles are built for longer rides across varied terrain. Although some components may be shared, differences can include suspension settings, gearing, electrical equipment, fuel systems and bodywork. Parts aren't always interchangeable, even between bikes from the same manufacturer.
Replacement intervals depend on riding conditions, maintenance and wear. Mud, sand and frequent off-road riding can accelerate drivetrain wear. Regularly inspect your chain for stretching, tight spots and damaged links, and check sprocket teeth for excessive wear. Chains and sprockets are often best replaced together when worn to avoid premature deterioration of new components.
Not necessarily. Dirt motorcycle plastics can vary significantly between model years, even when the manufacturer and model name remain unchanged. Radiator shrouds, mudguards, side panels and number plates may have different mounting points or shapes. Always check the specific year range and compatibility information before ordering replacement bodywork.
Common maintenance items include air filters, spark plugs, brake pads, chains, sprockets, wheel bearings, fork seals and engine servicing components. Maintenance requirements vary depending on whether your bike is two-stroke or four-stroke, how frequently you ride and the conditions you encounter. Follow your motorcycle manufacturer's recommended service schedule.
Some components, such as certain brake, suspension or chassis parts, may be shared between related models. However, engine components, exhaust systems, fuel-system parts and many servicing items are usually different. Even when two motorcycles have the same engine capacity, you should never assume their parts are interchangeable without checking the exact specifications.
