Top quality.
The original high performance filter. Used to be made in my home town of Riverside, California. Not anymore, but still great quality.

ST 1300 Impressive
Installed on my Honda ST 1300. I replaced the OEM filter with this K&N filter, I was surprised to actually feel an increase in horsepower. I use these filters on all my vehicles. Simple to install and very cost effective. The last filter you will ever need. You can't go wrong. I highly recommend.

K&N ALWAYS Means Quality and Performance
Got their tiny cartridge filter for my Yamaha WR250R on Amazon since it was cheaper than anywhere local. I think you can run alternate filter changes (change filter only once every other oil change) if you are only changing oil due to time not mileage. Since I ride maybe 2,000 miles a year these days I’ve stuck to that and have had no issues, but I feel better doing that with a high quality oil filter like a K&N.

As the headline says, fits/works for Yamaha XT 250 2021 edition. I've bought 4 of them now over the past year plus. Zero issues, cheap price and 2 day delivery.

Le quedó muy bien a mi moto fz25, probe con este K140 y el "K141", el 141 es ligeramente más largo. Buena compra.
