T-Rex Throttle.

The T-Rex throttle is the best, especially when paired up with the matching throttle cable which I believe T-Rex also supplies. This is a buttery combo that any modded out pit bike should have. Definitely a must have. Recently had bad crash and destroyed my first, so had to order a new one.
Thanks guys.

Worked very well on my 2003 KLX110

Added this to my made a Krisis clutch conversion and now the bike is fully manual clutch. Worked very well on my 2003 KLX110.

Kinetic cradle

Kinetic cradle, peg bar and skid is a must have combo. The skid plate fits great and looks clean. Replaced a BBR peg bar and skid plate because I couldn’t get a cradle to fit with it. The Kinetic setup is way to go.
