MXA TEAM TESTED: JGRMX ADJUSTABLE YZ-F/RM-Z ADJUSTABLE PULL-RODS
WHAT IS IT? The JGRMX YZ250/450F adjustable shock linkage system not only lowers the rear of 2010–2018 YZ450Fs and 2013–2018 YZ250Fs but also the 2017-18 RM-Z250 and 2017-18 RM-Z450. As with all links, it stiffens the initial part of the shock’s stroke while lowering the seat height. What makes the JGRMX shock linkage unique is that it allows the rider to go as low he wants to go.
WHAT’S IT COST? $279.99.

Got that? It does this by changing the amount of shaft travel per increment of rear-wheel travel. The linkage ratio makes the shock’s valving work more effectively when the situation calls for a stiffer response.
(2) Design consideration. It is important to note that a complete…
