Hey, I got some Parts from the Touratech Rallye Kit today, including 2 lock adapters.
They are machined from a single piece of aluminium and usually meant to be installed on the WP fork upgrade from Touratech, but it shouldnt be too hard to adapt them to the YZ forks.
One is already spoken for, but the 2nd one is still up for grabs.
Should you be interested in either the lock adapter or a specific part from the Rally Kit, PM me.
