The Bullet Brake takes just a few minutes to install. Just make sure ya have a towel under that part of the handlebar before ya start. You'll get a few drops of brake fluid during the installation.
Once it's tightened down, ya just need to pump the hand brake a few times then pump the bullet brake till ya feel it tighten up and you're done.
Their web page is dated but I contacted them about what part to use. They gave me a link for my 2020 DCT.

This is a dirt simple part to install, but then, if ya need someone to check your tire pressure for ya, you'll need someone to do this too.
