BMW Motorcycle Engines

BMW motorcycle engines are developed, designed, built, and tested to be the best for your bike. That's thanks to over 90 years of storied history belying that namesake Bavarian German craftsmanship excellence. Whether you ride packs a dual-cylinder or twin-cylinder boxer engine, a two- or four-cylinder in-line, or a two-cylinder opposed-twin (air/water cooled or otherwise), you probably know this firsthand -- every cubic centimeter of it, whether that's 800cc or a whopping 1802.

Your model has many of the same parts as today's motorbike engines, but better. They're highly durable and high-efficiency, and most importantly, they deliver superb performance in cold and wet or hot and dry weather. They only require minimal maintenance, too -- the kind that's quick and easy to take care of.

Of course, no bike engine lasts forever. Luckily, if yours is starting to go bad, you'll know it by the warnings.

Signs a Motorcycle Engine is Failing

They include:

• Poor startups
• Run-ons (when your engine keeps running after it's turned off); this can indicate anything from an incorrect-octane gas to carburetor problems or a failing solenoid
• Power loss; this can have any number of causes
• Worsening fuel efficiency
• Foul exhaust odors; in this case, your exhaust stroke could be failing
• Hissing, misfires, pops, spitting, and/or knocking noises; these may indicate a combustion problem

If you see any such symptoms, do an engine inspection and replace any parts that the results call for changing. Our auto parts store carries what you need.

Why Buy Genuine OEM Parts?

BMW Motorrad engineers and builds motorcycle parts guaranteed to fit your bike, right from the factory. Here's the shortlist of just a few of the engine parts you can find for sale online.

• Cylinder heads: these seal the tops of engine cylinders, which make up the combustion chamber. They contain shafts and engine valves.
• Cylinders: fuel combustion happens here; it's where your bike's power is generated. These are also called engine blocks.
• Pistons: these move up and down (a reciprocating motion), driving the connecting rods.
• Piston connecting rods: these link the pistons and the crankshaft. They move left to right, transferring rotational energy to the crankshaft.
• Crankshafts: these move motorcycle chains and ultimately, wheels. Their movement has to be timed right, a job done by timing chains or, in older models, timing belts.
• Engine valves: these are of two kinds: intake valves and exhaust valves. The former regulates the air and fuel in the engine, while the latter manages the fumes from combustion.
• Spark plugs: these ignite the mixture of fuel and air in the engine, enabling your bike to run on its own power. No motorcycle would work without them.
• Batteries: these have the relatively obvious role of powering the ignition system, headlights, taillights, and other electrical systems.
• Cooling systems: these are basically heatsinks; they help keep engines from overheating. Radiators, for instance, are becoming more common in them.
