Look back at any review of a Harley-Davidson touring model (and any other model than the Pan America), and there’s a good chance you’ll find a sentence or two about Harley’s weird choices when it comes to suspension. Specifically, the rear shock(s). It seems as though, in order to bring the seat height as low as possible, Harley has sacrificed ride quality in the back by putting on a shock with hardly any suspension travel. Sure it works, but it doesn’t do the human spine any favors.
In essence, an internal combustion engine is just a big air pump. Air comes in, then air goes out again. In a perfect world, engines wouldn’t even need air filters, but as we all know, there’s a ton of dirt, grime, and other airborne crud on the roads (or off the roads!) which, if ingested by your engine, could spell terminal damage. Or at least a lofty repair bill. Many of today’s motorcycles have well-designed intake paths and airboxes, but in many cases the stock paper filter element restricts the amount of air your engine could be breathing, robbing power in the process. Here we’ve gathered some aftermarket air filter options to help your motorcycle breathe as best it can. Of course, the most obvious plus side in doing so includes gaining more power, but in some cases you can achieve better fuel mileage. You can even save money in the long run, too, as some aftermarket filters are designed to be washable and reusable. See our top picks for best motorcycle air filter below, and remember, the prices will vary depending on the application.
