Yokomo 6 hole piston for BD9 High bigbore short shock

It is a new piston compatible with BD9 high big bore short shock. With 6 holes, jointly developed with AXON, which has more holes than before, it absorbs fine vibrations with good response and increases traction. The outer diameter of the piston is slightly larger than before, so it is tenacious during large rolls and prevents crumbling during high-speed cornering.
The hole diameter of the piston is the same as the BD9 standard 4 holes, but there is also the effect of increasing the diameter, so when replacing with this piston, first check the running with the standard shock oil number, and depending on the case, In addition, it seems that good results can be obtained with oils that are as hard as #50 to #100.
