Yoshimura RS-12 Stainless Muffler System (2023 Honda CRF250R)

Installing the new stainless Yoshimura RS-12 full system took me less than 20 minutes and the instructions were very detailed. All of the parts that came inside the box fit perfectly and it was easy enough that my novice mechanical skills could install it! In my opinion, Yoshimura is one of the highest quality exhaust…

2023 Yamaha YZ450F Triple Clamp Mod

I was told about this modification earlier this year (we will keep his name anonomous), however when I heard about it, I didn't think much of it. Once I thought about where the 2023 YZ450F isn’t great, I decided why not try it because you’re only as good as what you try. This is not…

REP Linkage System (2023 Honda CRF450R)

If you want to get rid of that plastic air filter cage system that sometimes doesn't seal all that well on the 2023 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,…
