I was looking into reflective stickers similar to the ones that are produced for the BMQ that you see on the back of the luggage. I found a company MotoEquip that makes them and asked if they had a kit for the Trophy and they sent me this email
Kurt, I would love to make a kit for the Triumph. However, to do that, we would need to borrow someone's bike for a weekend (don't need to ride it, just need to take measurements and go through several prototypes before we get the reflective kit "just right"). We make a lot of BMW kits because we have a local BMW dealer who has always worked with us when new models come out. We've tried to work with Triumph dealers in SoCal (our home base), but they've all told us No. So, in order to make a kit for any Triumph, especially the Trophy SE like yours, we would need to borrow someone's bike. Unfortunately, we haven't been able to do that.
If you have someone on your Triumph board who is in SoCal (near Pomona) and who would be willing to come over and leave his bike with us for a day or two (he can take it home at night if he wants), we'd be glad to develop a reflective kit.
Sincerely,
Fernando Belair
MotoEquip
I figure I would put this out there and maybe someone who is in the area could help and we could all benifit from this. Anyway just trying.
Kurt
