Hi all. Owner of a recently purchased Meteor 350 here.
I got the RE "Backrest Kit" yesterday (I had my dealer throw it in, on the purchase, but he was out of stock until this week). In the instructions, it states that the torque for the passenger grab-rail bolts is 25 N⋅m (c. 18.4 lb.ft., 221 lb.in.).
I'd add this info to the Master Sheet, but I seem to be viewing that in read-only mode. So I offer this info to anyone who is able and willing to do the update.
I have scanned the instructions (two-page, 2MB, PDF), if anyone needs to verify this.
