My Motopak Tail Bag came in today and I thought I'd share a photo of how it looks on the Speed Triple. It looks like it'll hold enough for a weekend and it will hold it securely. I'll have to find something to do with those side clips; there are for the integrated saddle bags which I did not purchase.
It seems to be very well constructed and I would recommend it. I paid around $70 shipped.
Anyone interested in this bag should check out eBay where the manufacturer sells them at discount.
