I used Bagster for decades and was more than happy with them, two up touring on a Fireblade, everything in it just a Kriega for the war depts knickers and make up.
Not too happy with the B M bags, I had one on my R1200R and I have one for the K1300R, both marked the tank cover, takes a lot of polishing to clear the marks out. If I were you I’d go for the Bagster.
Good luck and regards. Mick
