ransan, the Rivco TR3-3013-2 Sidestand Pad arrived a week ago, and it is the right part for the 2015 R3R. The pad is chromed aluminum, in one piece, very nicely finished and a nice snug fit. It secures with a 1/4" x 28 tpi set screw and I used Blue Loctite.
I think the chrome is way too blingy for a matte black Roadster so I sprayed it with black Plasti-Dip as a short term test. Satin black powder coat might be in the pad's future. I'm happy with the result and the price is right. Pics attached.
The buying experience at
www.squaredeals-ltd.co.uk was great. I received friendly emails for order confirmation, shipment and follow up.
