Honda CRF450R Hydraulic Clutch Improvement?

I stumbled on this via Johnny and Preston Campbell but thought it was a good mod to let you all in on. The 2023 Kawasaki KX250/450 master cylinder kit works on the Honda CRF450R and it makes the clutch action as well as the pull so much better! As you know the stock Honda clutch…

FCP Engine Mounts: 2023 YZ450F

I believe in aftermarket engine mounts when they are needed and to me (yes, this is an opinion) last year’s 2022 YZ450F didn’t need aftermarket engine mounts.

Pro Circuit Works Pipe and R304 Shorty Silencer (2023 KTM/Husqvarna 250/300)

I have been testing quite a few pipes/silencers for the 2023 KTM 250/300 as of late (FMF, Bills) and the Pro Circuit system is the latest that I have tried. The Works pipe and R304 Shorty silencer was tested on a recent Racer X Garage Build Husqvarna TC250 that I had the chance to ride.…

Living With: 50 Hours On The Kawasaki KX250 (56.1 To Be Exact)

Even though my kid has more than one 2023 KX250 laying around the house the one we use the most is our (Keefer Inc.) designated test machine. This KX250 gets the most usage and has seen the most hours. We are currently at 56.1 hours and have almost literally done nothing to it. I couldn't…

Akrapovic Evolution Muffler System (2023 Yamaha YZ450F)

The Akrapovic Evolution muffler system is one of the most beautiful looking systems out there in the market today, is well built, and has quality welds all the way around it. The change of shape in the Evolution muffler might take some getting used to but to me, it is one of the most under…
