2025 KTM 350 SX-F Garage Build

2 weeks ago | racerxonline.com | Simon Cudby |Kris Keefer

Build: Jamie EllisText: Kris KeeferVideo/Photos: Simon CudbyThis isn’t a shocking news brief. The KTM 350 SX-F is probably the most fun motorcycle you can swing a leg over. What happens when you add horsepower to an already fun machine? You get riders saying the “P” word. What is the “P” word, you ask? Perfect. This word isn’t used in a test rider’s vocabulary at any time. In fact, it’s forbidden to say. How can anything be perfect in the world of motocross?

Can’t believe it’s already over! It seems like Supercross just started but here we are banging on the door of outdoors. SLC proved to have some fireworks so let’s break it down a little right here. Cooper Webb: Your 2025 AMA SX Champ! There is no one as strong minded as Webb and from the outside looking in it looked easy but from what I heard, it was nothing but smooth on Friday.
2025 Kawasaki KX250 Garage Build

1 month ago | racerxonline.com | Simon Cudby |Kris Keefer

Build: Twisted DevelopmentText: Kris KeeferPhotos/Video: Simon CudbyThe Kawasaki KX250 has an all-new chassis, suspension, and an updated engine as well as a smaller airbox for 2025. To me, Kawasaki made the chassis and suspension better, but I feel like the engine has lost low-end snap as well as torque feel.
2025 Yamaha YZ125 (Old guy on a small bike)

1 month ago | pulpmx.com | Kris Keefer

No hate comms, but I am not a huge two stroke guy as you may all know. This doesn’t mean I don’t like riding them when I do but if someone gave me an F, Marry, Kill to play and the 125 was one of the three choices, I most likely will be killing the 125. Sorry, peace and love. I get to test all kinds of two strokes but I can genuinely say that 125s are usually the most fun for me in the two stroke realm.

I will be honest with all of you. I wasn’t even going to type about anything this week because (to me) the results as well as the race itself didn’t mean that much to me after what happened to Jerry Robin. I understand that some of you may not want to read this and that is ok, but sometimes I like to put my thoughts to paper (or in this case to the keyboard). So if you get through this, I hope it somehow resonates with you.

The Yamaha YZ125 hasn't changed since 2022 but in 2025 there is still a lot of FUN to be had on the bLU cRU machine. Get some insight on who this small bore two stroke is for and listen to Keefer as he speaks his best two stroke language to you.

Daytime Program: Seattle

Seattle was a little more exciting than last week right? Just when you thought it would be a muddler, the SMX track crew did god’s work by keeping the track great all night. We had one of the toughest tracks of the year Saturday night but it could have been so much worse if it wasn’t for the Dirt Wurx guys! Since we normally shit on them, why don’t we say “great job”! Kudios to them! Here is Daytime from The Emerald City.
