I've got a Honda VTR250 and I think the rear vision is shit however I know nothing to base it against. I'm a bit bigger/fatter than the typical bloke and when I try to view the lane behind me, I just see my shoulders and arms. If I bring my elbows right in, I can just see the lane marks on either side. To be able to see behind me, I have to angle the mirrors to view the side lanes at quite a sharp angle, then move my head about 30-40cm towards the mirror and then I can see if someone is behind me. I've noticed some bikes have mirrors lower than where Honda put them on this bike. I've also read the mirrors on the edge of the handlebars thread, and think that might solve my problem. I guess the question is, what is the correct technique to monitor what's behind me and the correct mirror position? Also, I'd like to buy convex mirrors to replace the flat mirrors which I completely hate. My german cage has side rear view mirrors with the outer 1/3rd convex and they are completely awesome. Does such a product exist for bikes?
