These rear shock linkage plates, with a different geometery to the standard, reposition the rear shocks for a more 'lively' damper action. They give a greater ride height, less suspension sag and more bounce for those who like the trick riding style. Still maintains the Montesa superb 'grip anywhere' rear-end feel. Made by V-Mar of California from 6.5 mm Dural alloy, anodised black finish. Will fit all Montesas from 1997 onwards including the 4RT.
