In this video I’m doing a simple oil change on a 2025 Honda CRF125F Big Wheel. If you’ve got one of these little bikes in the garage (or you’re wrenching on your kid’s ride), this is one of those basic maintenance jobs that makes a huge difference in how long the motor stays happy. I walk through the oil change process from start to finish so you’re not guessing what to grab, what to remove, or what to look for while it’s draining. The big takeaway is: keep it clean, don’t overthink it, and stay consistent with your oil changes—especially on a bike that gets ridden hard. While I’m in there, I also point you to a few helpful extras I keep around the garage like a dedicated oil change kit, chain lube, and some solid youth riding gear. If you’re new to dirt bike maintenance, this is an easy win that’ll build confidence and keep the CRF125F ready to ride.
