I own the small "glove box bag". The clear window is way too small for a map, but I can put directions or pieces of a map in it. More importantly, I can put small items that need to be close in the bag. Things like toll cards, change, a hot dog etc. It works for me.

I have the small 'glove box bag' mounted on my RT too, you can put lotsa things in it - see my avatar pic!

IIRC, that little bag was originally sold by BRP as something for the GS/RS/RSS/ST's, with a couple of different attachments included to suit fitting it to whichever model you had.... it wasn't hard at all to slightly modify the front attachment so it'd fit the RT, & all it took at the rear end was a short adjustable strap around the main frame spar with a short trailing length & a clip that passed up between the seat front & the glove box rear that made it easy enough to release so that I could still lift the 'glove box bag' (once Max was out of it, of course!

) and get into the glove box proper when I needed to. I did also cut a tiny slot in the rear base of the bag to pass a strap thru that allowed me to connect a strap onto Max's safety harness so he couldn't fall off.
And I also had a bigger but very similar 'pet carrier' bag (it was actually the smallest we could find, Max weighed in at less than 5 pounds dripping wet!) so that he could travel in fully enclosed comfort if he felt like it on longer trips, but he rarely did that. Most of the time he liked to at least have his head out in the breeze to get the wind in his face - he was very proud of his doggles & riding jacket & he loved to show them off to other road users as we passed. He rode like that with us on a variety of machines for more than 15 years, and now that he's passed on, he's very much missed.
I doubt that BRP will still be supplying that particular tank bag, simply because the Spyder models it was originally intended for are no longer produced, but it really shouldn't be all that hard to find a suitably sized tank bag with attachments that either suit or could be readily modified to suit fitting it onto an RT. You could even secure it forwards with a strap around the steering shaft, and there's a relatively easily accessed main frame spar under the front of the seat that can secure the back end.... you just hafta think a little outside the box, cos there won't be too many tank bags made specifically for a Spyder RT - after all, they've already got a glove box & more storage than some sports cars! :thumbup:
Have fun & Good Luck! :cheers:
