Fart humor has been a staple of soundboards for years, and motorcycle exhausts that mimic flatulence became a natural spin on the classic fart sound. Riders and editors noticed that a lumpy Harley idle at low revs lines up perfectly with that joke, so short clips like this spread through meme pages and group chats as a ready-made punchline. It sits in the same family as the broader fart meme sound trend, used less for realism and more for the instant, childish laugh it guarantees.
About this sound
A short Harley-Davidson motorcycle engine rev that sounds like a loud fart, used as a funny sound effect for bike fails, pranks and meme edits.
This clip captures a Harley-Davidson V-twin engine sputtering and revving at low speed, and the uneven putt-putt rhythm sounds uncannily like a long, wet fart. The choppy exhaust blasts start rough, wobble in pitch, then trail off in a sputtering finish that sells the joke. It is not a clean studio rev, it is raw, throaty and a little ridiculous, which is exactly why it lands. Played over a serious bike shot or a straight-faced moment, it instantly undercuts the toughness and turns the scene into slapstick.
