Engine & Engine Electrics

BMW motorcycles are kept for more years and ridden more miles than those of other brands. The number of 20-, 30-, even 40-year-old BMWs still being ridden regularly is astounding. The need to keep the older bikes running has inspired countless entrepreneurs and cottage industries to create reproduction or alternative parts to satisfy demand. Sometimes these products are created to replace OEM parts that are no longer available. Other times they’re developed to provide a performance advantage over an original part. And of course, the after-market can always be counted on to provide parts that are simply less expensive than originals.

In general, it’s never a bad idea to stick with BMW factory original parts, but sometimes an after-market alternative really is the smart choice, even when an original part is still available. Obviously, with critical engine & engine electrics parts, making the right decision is important. We have plenty of options for your needs in our selection of reproduction BMW motorcycle engine and electrics products. The reproduction or alternative BMW motorcycle engine and BMW motorcycle engine electrics components we sell at Bob’s are proven, high quality, reliable parts you can install with confidence. We would not sell them otherwise. These parts will perform as well as if not BETTER than the OEM parts they were made to replace. And in most cases, these parts come at a more affordable price too. Win-win!

Browse the alternative BMW motorcycle engine and engine electrics parts here to find the parts that, eventually, nearly every rider must replace during the lifetime of their bike: starters, fuel pumps, valve covers, ignition controls, alternators, coils, diode boards, and much more. Remember, we’re here to help. Please contact us if you have any questions or need further assistance of any kind.
