There are numerous examples of the best and worst motorcycle engines built by the major motorcycle brands, and even among the "best" there can be significant variation.The longitudinally mounted, liquid cooled, flat-six engine that powers the Honda Goldwing is a prime example of a bike engine with a long lifespan, often exceeding 250,000 miles. Trying to measure that lifespan in years gets tricky since some riders use their touring bikes purely for pleasure, adding just a few thousand miles to the odometer per year, while others use them as commuter vehicles and rack up 2,500 miles or more per month.The secrets to the Goldwing engine's long life lie in Honda's use of quality components when designing and building its flagship touring model. Motorcycle engines of lesser quality see shorter lifespans, although most reputable major motorcycle brands' engines should approach six-figure odometer readings, with touring bikes and cruisers designed to last longer than sport bikes and dirt bikes. We'll assume the motorcycle encounters reasonable operating conditions and proper maintenance during its life as even the best engines fail prematurely when abused.AdvertisementAdvertisementRead more: The 5 Best And Worst Motorcycle Engines Built By Major BuildersGetting the most life from a motorcycle engineAdding oil to a motorcycle engine. - Aleksey Shvedov/Getty ImagesNeglect shortens a motorcycle engine's lifespan more than time or miles. Regular maintenance is the best way to ensure a motorcycle engine lasts as long as possible. In addition to some simple tips for motorcycle maintenance, it's important to follow the manufacturer's recommended maintenance schedule as closely as possible. Its recommendations will include which types of fluids and filters to use, in addition to timetables for periodic cleaning and replacement to get the most life from the engines put into their motorcycles.As with the rest of the motorcycle's components, time plays a factor in the engine's lifespan as well. This is especially evident if the motorcycle is neglected while going unused for long periods. Storage conditions can affect the lifespan of a motorcycle overall. If left exposed to the weather and sun's UV rays, deterioration comes quickly. However, keeping a bike in an uninsulated shed isn't much better as temperature extremes and rodents can cause extensive damage.Long periods of neglect when not riding the motorcycle shorten the engine lifespan as rubber seals meant to keep the inside of the engine separate from the outside dry out, crack, and fail. Gasoline evaporates over time, leaving behind a sticky residue inside the engine's fueling system.AdvertisementAdvertisementUltimately, riding the motorcycle the way its engineers designed it, performing the recommended routine engine maintenance, keeping the bike clean, and storing it properly when not in use will ensure the longest lifespan for your motorcycle and the engine that powers it.Want the latest in tech and auto trends?
