I just ordered these off EBay from Stealth Racing Technology. I like the idea of turning the bleeder a little like the brake bleeder.

Stainless Steel Fork Bleeders (4mm Threads)
as seen in TRANSWORLD/MX magazine.
These unscrew a few turns to release pressure like brake bleeders. This fail-safe design won't leak oil, allow air pressure to build-up from rebound, or let water in from high-pressure washing that causes internal valving corrosion and oil contamination (push-button styles can do these things). They also won't break off like others often do.
*Fits all KTM's with stock forks using 4mm threads.*
KTM's with factory works or WP forks with 5mm threads use FRK-SS
SX 65 (requires bar removal to install)
SX 85/125/250/450 and SX-F 250
XC/MXC/EXC/EXCR 200/250/300/450/520/525 and 530.
