2020 Kawasaki KX250 Top 5 Mods

Kawasaki did a great job for 2020 on improving the KX250’s overall engine character as well as getting a much better suspension spec.

Twin Air Power Flow Filter Kit (Yamaha YZ450F)

If you want to get rid of the somewhat janky stock air filter cage system of the 2018-2020 YZ450F, go with the Twin Air Power Flow Filter Kit. To me the Twin Air YZ450F PowerFlow kit is the best all-around filter system for the YZ450F airbox. Why? With this kit, Twin Air replaces the stock…

FMF Vs. Pro Circuit (2020 Yamaha YZ450F Muffler Comparison)

Yamaha did a great job with the stock muffler and I bet if you ask any aftermarket muffler manufacturer they would tell you the same thing. If you’ve seen my social media pictures while riding the Yamaha YZ450F, you will see that I run the stock system quite a bit. Why? Because it’s really good!…

KiT Trackside Training

Garmin Forerunner 935

I have used the Garmin 910XT for years to keep track of my training, my lap times, and my heart rate, but Garmin has since discontinued my favorite training helper.

Akrapovic Evolution Muffler System (2020 Honda CRF450R)

This is embarrassing, but I am going to be completely honest here… I think about the Honda CRF450R a lot. More than other machines. I mean I will literally wake up in the middle of the night and think of things to test in order to try and make the Honda chassis calm down a…
