Getting a new motorcycle is an exciting prospect, but once you fire it up for the first time you’re left with what many deem a great responsibility: breaking in that new engine.
What is engine break in? Fresh from-the-factory parts appear smooth, but they actually have microscopically rough surfaces that need to rub against their counterparts and bed in, and that happens during those first miles of use. Once the components are polished smooth and broken in, friction is reduced, sealing is improved, and you’re ensured good power, fuel economy, and reliability.
There are a lot of sliding and rotating parts within an engine, but what everyone gets riled up about when discussing engine break-in is the seal between the piston rings and cylinder walls. And rightfully so. Ring seal is the a key condition that’s going to affect performance and longevity, so it’s worth thinking about.
