It looks to me like
these folks do it right. The brackets are heavy, and the rest is adjustable. The bad news - they dont yet offer Speedmaster or America rests, nor will they send one they think might be close. The good news - I'm going to send them a spare seat I have and they said they would probably like to develop rests for more Triumphs. (Let's hope so anyway)
The brackets you see in
these photos (click a bike's link) mount under the pillion seat.
A sample installation
It wouldn't hurt our chances at a Triumph line for as many of us here as possible to call them and show there is interest in Triumph rests.
