So a couple of people have mentioned top boxes and rear carriers lately, and how they look fitted. I thought I'd post a few pictures of mine, so's people can see for themselves what it may look like.
As you can see, it doesn't look particularly good (does a top-box ever
look good..?), but [as any of you who've seen my bike already are probably aware] I'm not too precious about looks and things; my XSR is my only means of transport, and a top-box is so useful day-to-day that it's basically essential, for me!
The XSR is so controllable and well-balanced that even when the box is laden well over its given weight capacity there's no real problems with drop-in to slow corners or anything of that sort, and there's no noticeable speed-weave at your regular, legal-ish motorway speeds.
Touring-wise, though, if I'm travelling one-up and I have to carry much more than just a couple of changes of clothes or whatever, in future I expect I'll probably leave the top-box at home and carry a big duffel-bag/roll-bag type thing, lashed across pillion and rear carrier. It's difficult to fit much on the pillion seat when the top-box is on - not only does it reduce space quite a bit, but it also makes the tie-down points a bit harder to access.
, hope this info helps! If you'd like me to take a tape-measure to it, or photograph from a particular angle, feel free to let me know!
