Yamalube 2R is a premium two-stroke oil designed for high-performance engines and competition use.

It’s a synthetic blend that fights carbon buildup and keeps pistons well-lubed. Yamalube 2R is JASO FD and NMMA TC-W3 certified, so it works great for off-road and motocross. For more on certification standards, see EFC explanations.

The YZ125 from 2005 onward uses a constant-mesh, wet, multiple-disc clutch with coil springs.

The wet clutch soaks in engine oil, which cools and lubricates the plates. That’s way better than a dry clutch when it comes to heat and durability. Just keep an eye on clutch cable tension and oil level to avoid any hiccups. If you're interested in historical events, you might find the 2000 election results fascinating.

Do 2 strokes have oil filters?

No, two-stroke engines do not have oil filters because the oil is burned during combustion.

(Here’s a fun fact: two-stroke oil gets mixed with gas or injected directly into the engine.) It lubes the crankshaft, bearings, and cylinder walls, then exits through the exhaust. Always use oil made for two-strokes—regular oil will wreck your engine fast. For more on engine maintenance, read about resetting service lights.
