Yoshimura RS-12 Stainless Muffler System (2021 Kawasaki KX450)

The stock 2021 Kawasaki KX450 is pretty damn good machine, but that muffler looks atrocious right? We called up on Yoshimura to see if we can get a more attractive aftermarket muffler system that is actually better than the stock system.

Thor Terrain Off-Road Pant And Jersey

Although I ride year around, winter in Southern California is my favorite time of year because it means wet dirt, awesome traction, and prime trails.

The Makings Of A Great WP Pro Component Settings On The KTM 450 SX-F (With REP Suspension)

Let me preface this article with how much I like to ride the KTM 450 SX-F. But… Yes, of course there is always a “but”, right? I like a lot of things about the KTM 450 SX-F, but the stock suspension isn’t one of them. The AER fork is a slight headache for me as…

On My Own Dime: My Favorite MX Tires

To keep up with these ongoing “On My Own Dime” articles I thought it would be informative to write about a few of my favorite tires.
