2025 Optional Renthal Handlebar Bends For Your Bike/Size

We are back for 2025. Going all detailed on bar specs! When it comes to handlebars, it is very particular between each rider. However, I have and still am a big pain in the butt with a rider triangle. The height, width, rise, and position is very important to me between each bike that I…

X-Trig ROCS Tech Triple Clamps (Triumph TF-250-X/TF-450 RC Edition

It’s hard to find aftermarket triple clamps that are better than stock these days. 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 (on all motocross bikes) sometimes…

Tested: Aluminum Throttle Tubes (Bearing Type and Non-Bearing)

First, a lot of other brands are using a CNC-machined 6061-T6 aluminum throttle tube so that is nothing groundbreaking. This isn’t…

2025 KTM 250SX Pro Circuit Works Pipe and Shorty Silencer

There is something about a crisp sounding two stroke. I am not a huge two-stroke rider but to me the best thing about a two-stroke is that crisp/over-rev sound that happens right before you land from a jump! That gets me going! But what about going to an aftermarket pipe/silencer? Does it make the bike…

OEM Yamaha Fully Assembled Wheelsets (Are They Worth It?)

Did you know you can get fully assembled wheel sets from Yamaha for your YZ125/250 as well as your YZ250F/450F? I have been on this bandwagon for a while with the Yamaha wheelsets because quite frankly Yamaha makes the best stock OEM wheelsets out there. They are stronger than other OEM wheelsets as well as…

Renthal Bar Bends Of The Pros

REP Linkage (2023-2025 Yamaha YZ450F)

Yamaha changed the linkage ratio for 2025 on the YZ450F. Yamaha was looking to keep the rear up so basically the whole curve of the 2025 linkage ratio is stiffer and that is why Yamaha went down on their spring to a 5.6 N/m from a 5.8N/m spring on the 23/24 models. When Mark Johnson…

Yamaha YZ450F Flywheel Weight

If you’re a Yamaha YZ450F owner you know that your bike can be a handful at times. If it’s not a handful then you can disregard this test altogether. For me the YZ450F is one of the best bikes in the 450 class for 2025 but it still needs some work to be an easy…
