Pro Taper ACF Handlebars

Pro Taper has graced my test bikes for quite sometime now? Why? Simple. I get more flex and comfort out of a Pro Taper EVO bar than its competitors. Some people may not be as picky as me on bars, but I am very sensitive to rigidity when it comes to handlebars. Pro Taper has…

Brake Modifications And What They Do On The Track

You can only go as fast as your brakes allow you to slow down. That doesn’t sound quite right, does it? But if you don’t have good stopping power on your dirt bike, chances are you will not be able to get around the track or clip down that trail at any reasonable rate of…

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…

FMF Fatty/Gnarly Pipe & Powercore 2 Silencer (2022 YZ250)

The 2022 Yamaha YZ250 is a hell of a fun bike to ride. Even though I am not a huge two stroke guy, I had a great time riding it and thought it had a better engine character than the previous model. The new intake design really helps smooth the power down low and makes…

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…

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.…

Raptor Titanium Offset Footpegs (Yamaha YZ250F/450F)

If you’re a Yamaha guy, chances are you may be looking to get your cockpit a little more roomy right? The Yamaha YZ450/250F needs a better rider triangle in stock form so I scoured the internet to see if I could find a way to improve it. A lot of factory motocross teams run Raptor…

Acerbis K-Future Handguards

I have gone through a few hand guards over the years and have had my favorites, but recently we got to try the Acerbis K-Future Handguards for our KTM 250 SX-F test bike. The Acerbis K-Future Handguards have dual-injection covering, a lightweight, compact yet flexible flap design that can protect your brake/clutch pumps. I like…

Dubya Edge Wheel Set

I will be straight up with you all… I am not a huge fan of $1500.00 wheel sets. Most of the time, I am a big stock wheel/hub guy, but in some cases I do need a little more security or toughness in my wheels. I am a big believer of bringing an extra set…

FMF 4.1 Muffler System (2021 KTM 250 SX-F)

My son and I have been going back and forth on mufflers for his KTM 250 SX-F and have went though about three until we settled on the FMF 4.1. We have tried the HGS (which was good), a Yoshimura, as well as a Pro Circuit system, but for his riding style and what he…
