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!…

2020 450 MX Bracket Shootout (Fourth, Fifth, Sixth)

As long as I can remember, shootouts have been a staple in our industry. I remember being an 11 year old kid reading about the 1987 80cc Shootout in Dirt Rider Magazine and then proceeding to ask my dad for a Honda CR80 because it was the winner. Little did I know that just because…

YZ450F GYTR Tall Seat

Yamaha has an accessory division called GYTR and when it comes to accessories for your YZ they have tons to offer. I wasn't quite happy with the “pocket” feel that the stock 2020 YZ450F seat has to it once the foam is broken in, but managed to stumble across the Yamaha Accessories tall seat while…

2020 Yamaha YZ450F In Depth First Ride

For 2020, Yamaha is the only manufacturer to have any significant changes done to their 450cc motocross machine. With over 15 updated engine components, over 10 chassis components, and a suspension valving makeover Yamaha wasn't resting on their 2019 450 Shootout success. If there was one 2020 450 motocross bike that I was anxious to…
