Ok 2024 KX450 Owners, Warning you up front! Swapping out the head pipe on these new models is a PAIN! Ask Kris Keefer and Michael Lindsay! The DCMX 3/8 T handle paired with a 12mm Tekton Swivel socket is the ultimate solution! This is an absolute must if you don’t want to have to turn those headpipe nuts 1/8 of a turn each time with an end wrench.
