Bicycle stuff makes excellent motorcycling gear. Most of my cold weather gear is actually designed for riding a bicycle in winter.
When I was putting together some soft luggage recently, my first stop was looking for some bicycle touring panniers I could repurpose. They would work well, because bicycle panniers tend to be narrow and shaped to give you maximum heel clearance when you pedal. They would give you a bit more clearance for you legs on a motorcycle, in case your leg got dragged behind you.
