Q&A

Q: Will this fit on a 2024 street triple rs?
A: The plate of the RAM-B-342U is .25" thick.

Q: How would I REMOVE this from a bike? I took off the ball, but it seems theres still the bottom piece in my stem and I don’t know how to remove it?
A: You would just need to back the screw out the RAM-B-342U.  There can be some resistance from the the nylock nut internally, but it will eventually back the nut off allowing the expansion plug to be removed from the bore hole.

Q: What is the safe Torque when you tighten the screw with 3mm Allen Wrench?
A: There isn't a recommended safe torque for the screw included with the RAM-B-342U, you will want to tighten that until the expansion plug has been squeezed between the washer sets and is secure in the fork stem hole.
