We checked out the arm rests for our 2018 RTL from BRP for the OEM version, Rivco, Show Chrome, Corbin and Diamond R. Gloria thought the BRP, Rivco and Corbin versions were a bit too short. For her they were basically elbow rests. We had Show Chrome armrests on the last 2 Goldwing trikes, a 1500 and an 1800, and they served well, held up and were quality parts. For the Spyder RTL however, we chose the armrests from Diamond R. They are also a quality product and easy to install. I like the single mounting bracket that spans from one side to the other under the seat. Very robust and the one piece mount spreads out the forces across a large area making it very steady. When not in use they also fold flat against the passenger backrest, and Gloria likes that the armrests themselves are longer, so her whole arm is supported.
