Kit includes two bleeder valves for use on most KYB inverted forks with a M5 x 0.8 air bleed screw in the fork cap. New ultra-compact, low profile design is only 11 millimeter high installed. Stainless steel body is stronger, will not corrode, and fits on many late model Japanese off-road motorcycles. Allows bleeding of air pressure without tools, reducing harshness caused by air build-up. One of the easiest bolt-on upgrades you can make to your forks, simply replace the OEM bleeder screw with the micro bleeder.
