I bought two of these filters for my son and his buddy. They both ride Honda CRF250Rs. They were easy to install and appear to be made of a quality filter media. I have used K&N filters in autos before with great results. Riding time will tell how well they filter oil in the bikes.

I recently purchased the K&N drop-in filter for my '13 Honda CR-Z and love it. Before installing the filter I logged my car's performance using Torque, and then again after installing the filter. The difference in performance was not only noticeable within Torque, but I can feel the difference while driving.

The fit was not perfect, it was a little too big but still fit with a little convincing. It really woke my 2000 Honda Shadow VLX600 up. I was really impressed with how much of an improvement it was. I would buy another K&N filter.
