Akrapovic Evolution Muffler System (2021-2022 Honda CRF450R)

I had the initial impression of the Akrapovic Evolution muffler system as I was doing a MotoConcepts/Bullfrog Spas Honda team test. I noticed that they have been running Akrapovic systems on their bikes, so I asked if I could borrow one to see how it worked. Akrapovic's Evolution line is their full titanium muffler system…

2022 Yamaha YZ250F GYTR High Performance Engine Kit

There aren’t very many OEM manufacturer accessory divisions out there that offer actual engine mods for their machines. Oh wait, there isn’t one! The only manufacturer that offers anything engine related is Yamaha. KTM used to have KTM Factory Services but that has been shut down yet GYTR is still going strong with a long…

Written/Tested By: Gary Sutherlin The 2021 Kawasaki KX450X has been a bike I’ve been interested in putting some time on ever since Kawasaki decided to jump back into producing an off-road 450.

X-Trig ROCS Tech Triple Clamp (2022 YZ450F)

It’s hard to find aftermarket triple clamps that are better than stock these days, especially on the Yamaha YZ250/450. So much is involved in making a triple clamp that flexes enough, but also has enough rigidity to aid the machine in corners as well. With the triple clamp flex character so important to chassis handling…

2022 Honda CRF450R baseline Settings

Even though the Honda hasn’t changed much for 2022, Showa as well as Honda worked on creating more hold up from the suspension. This lead us to create another baseline setting for you 2022 owners. The ECU has also been updated, but there is still some lean pop on de-cel so we are currently working/looking…

Hidden Gems: Fuel Clothing Socks

It’s just flipping socks right? Well, yes, but actually no. I am very picky on socks because that is the one part of my body that I sweat the most. My feet are fairly sensitive so when I get a pair of socks that are hard or rough to the touch, I am out! I…

2022 Yamaha YZ250F First Impression

The Yamaha YZ250F doesn’t have that many changes to it for 2022. Yamaha lightened up the hub, sprocket, chain and they installed a 2.15 rear rim (instead of the 1.85 2021 rear rim), as well as went to Dunlop MX33 tires with a 110 rear tire in stock trim. The fork’s low speed damping was…

Akrapovic Evolution System (2021-2022 KTM 250 SX-F)

When you purchase a 2021 KTM 250 SX-F TLD version the bike comes with a slip on Akrapovic Evolution muffler. However, I know that sometimes, certain machines react better to full systems rather than slip ons, we decided to get the full Evolution system to see how it changes the KTM 250 SX-F’s engine character.…
