Although it’s not Green Sticker legal, the CRF250RX sits between the new CRF250F trail bike and CRF250R motocrosser So I get a sense of nostalgia when I see a CRF230 on the trail or in the back of someone’s truck.

The Honda CRF250F is powered by a 249cc air-cooled single-cylinder four-stroke engine. It features a 71.0mm x 63.0mm bore and stroke, and a 9.6:1 compression ratio.

Any non synthetic 10w40 will work. I ran the regular white bottle / blue label Valvolene 10w40 motor oil in my CRF150F for 5 years without a problem.
