Coppersmith Aero/Hybrid Fork

Coppersmith Racing Suspension has been around as long as I can remember and they have been mostly known for their Ohlins suspension set-ups.

Yoshimura RS-9T Stainless Full System (2020 Honda CRF250R)

The 2020 Honda CRF250R is much better off the bottom end than the 2018-2019 versions, but we wanted to test the latest full stainless Yoshimura RS-9T to see if it helped the stock Honda’s engine character at all.

Pro Circuit Aluminum Throttle Tube

Have mostly been a plastic throttle tube type of guy, but I have appreciated the toughness of an aluminum throttle tube when I have some medium to large sized crashes. The one thing I usually don’t like is the firmness of the aluminum throttle tube when landing as well as how big they feel in…

Seat Concepts OEM Race 2.0 Complete Seat

My standard 2020 KTM 450 SX-F Factory Edition seat didn't last long. The foam broke down, the cover ripped and my butt wasn't happy with me. I have pictures to prove it, but I'll spare all of you that nasty image. Enter Seat Concepts. After all of these years I have yet to experience any…

The basic idea is a wide but fairly conventional 2024 billet aluminum footpeg with a teardrop-shaped sort of heel peg welded to the rear of the normal peg. The teardrop ankle-saving portion…
