Kawasaki has an all new KX250 and Pro Circuit just recently came out with their latest Ti-6 version for the new green machine. With airbox changes to the 2025 version as well as a different cylinder head, this forced Pro Circuit to come up with a new headpipe and muffler. We have put time on…

YZ 250/450F Brembo Brake Mod (Re-Visit)

So are you tired of that spongey feeling stock Yamaha brake? Since I get to ride all the bikes, I would have to say that the Brembo system is one of the best feeling brakes out of all the MX machines. However, a little mix and matching can get you a more linear feel than…

Why A KTM 250 SX-F FMF Megabomb Headpipe Is Better On A KTM 350 SX-F

I originally posted a photo of a KTM 250 SX-F FMF Megabomb headpipe mated to a KTM 350 SX-F 4.1 FMF muffler and my DM’s flooded with questions. Why does it do? Why stick the 250 headpipe on the 350? Normally when you purchase an aftermarket muffler system you usually get a smoother roll…

Yoshimura RS-12 Stainless System (2024 KX450)

Written By: Eddie Laret/Kris Keefer We all know Kawasaki left a lot of room for improvement on the muffler side of things on the 2024 Kawasaki KX450. We have tried a number of mufflers to help increase the low end torque and have been happy with a couple. The latest muffler we tested was…
