Hi , I put some 2" Rox vario risers on my 2006 Tiger 955i some time ago to bring the handlebars further back and higher up, to try and take some of the strain off my upper back and shoulders as I lean forward to reach the bars. Even at 6' 2" it's still a bit too much of a stretch for me to be truly comfortable. When I take my hands off the bars and use my finger tips to control the bike it feels much better, so I don't need much more of a change on the bars to get into that perfect "sit up and beg" riding position. I just need the bars further back and higher up a bit. Soooo.....to get to the point.......would it be safe to put another set of 2" vario risers on top of the risers that are already on the bike to get that perfect riding position ?? Or do you think there may be a risk of flex, snapping the risers when putting hard steering inputs in, or from vibrations, etc ?? Or can you think of a way to get the desired effect without changing the bars ?? Any advice would be appreciated, thanks, Graeme.
