Until now, upgrades for the latest-gen 39mm fork were slim. Some riders modified their motorcycles to the earlier dual-damper setup by ordering previous-gen parts, but it's a somewhat expensive undertaking to land at what is effectively a less-refined fork. The only way to upgrade those are to purchase items like cartridge emulators. Instead of going that route and emulating the real deal, why not nab this genuinely improved suspension layout for less money?
