All of our stems are made of 4130, 1 and 1/4, .0125 wall moly and are tig welded togther with super missle rod. Two things that we do different on our stems: 1) take "bump steer" out and 2) double sleeve our stem down to the top bearing. Essentially, we take the flex out of the top of the stem by adding a peice of 1", .0125 wall inside of the 1 and 1/4 wall, 0125. Stems are avaliable in +0, +1, or +2, and 7/8 or 1 and 1/8 clamp. Available for Yamaha, Honda, Suzuki and Can-Am 800.
