Despite being such a looker, I think the 613sh is going to be a great riding jacket. The thickness of the hide gives a sense of security and huge props to Schott for practically overdoing the arm length. My Triumph has old school beach bars which are kind of wide and low slung and the mobility and reach on the jacket was excellent right out of the box. I’m thinking the shoulders might require a bit of break in for the Harley guys with their ape hangers. Another plus was the non-snap collar just seemed to work and fit better when the jacket was fully zipped with the lapels folded in (which is how I often wear a Perfecto when riding).
On this count, I saw back in the autumn (but then forgot to post here, I think) that a motorcycling magazine reviewed the 613SH in particular as a riding jacket (the title just says Perfecto but the review is specific).
