Pro Circuit Ti-6 Muffler System (2024 KX450)

Aftermarket muffler manufacturers rejoice! The 2024 Kawasaki KX450 has A LOT of room for improvement with its muffler system. The stock muffler is choked up and makes the KX450 feel somewhat lethargic for a 450. Yes, I know what you’re thinking.. “Kris, it’s a 450, how much power do we actually need”? You would be…

2024 Gas Gas/KTM/Husqvarna 250 Four Stroke Comparison

Written By: Gardner Tarlow Austrian triplets! Can you really go wrong? For 2024 all three of the Austrian bikes although different in color took on very similar personalities. For 2024 the Gas Gas MC250F is all new from its 2023 predecessor, and although all new for Gas Gas it’s basically the red headed triplet with two…

2024 KX250 Baseline Suspension Settings And Optional ECU Map
