Long Term With The 2021 Yamaha YZ 125X

Written By: Dr. Gardner Tarlow Can the YZ 125X really serve as a multipurpose moto-enduro bike? If you have read my previous article on the 2021 YZ 125x you know that Kris gave the average Joe rider (me) the opportunity to test the bike. Well luckily for me Kris asked me to continue to ride…

2021 250/450 Motocross Gearing Specs

I have spent a lot of time testing on each 2021 machine you see below. I went back and forth on several bikes to see which gearing would be good for the average rider. I did my evaluations on tight clay based tracks to flowing sandier based type desert courses. Since the word “gearing” is…

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. I will say that the stock KX450 muffler system works pretty damn well, but…

The Weekend Race Set Up 3/6-7/2021 (Mesquite)

ARC RC-8 Clutch Assembly With Aluminum Black Smooth Lever

I will admit that I am usually a stock perch/lever or a Works Connection Elite Perch/Lever kind of rider and although I have tried many different perch/lever set ups those are the two that I normally gravitate towards or back to. I have tested a lot of combos and have come to the conclusion that…

Works Connection Pro Launch Device

Works Connection had an older start device that used the old school spring and plunger design, but now have since gone to a magnetic locking system on the Pro Launch device. This has been in circulation for a few years now and is one of the most no fuss systems on the market. It’s so…

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…
