Review: Pro Circuit Ti-6 Pro “BC” (2024-2026 KX450)

It’s not rocket science that the 2024-2026 Kawasaki KX450 mufflers are plugged up! There is a ton of room for improvement with the engine character with just a slip on. “Kris, it’s a 450, how much power do we actually need”? You would be right, but also there is a fine line of too slow…

Tested: Yoshimura RS-12 Full Titanium System

Yoshimura RS-12 Stainless Muffler System (2026 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…
