Wobbly -
I see you're still using the forward mounting holes on the upper clamp.
If you switch to an RT gauge mounting bracket, you can move your bars back to the rear mounting holes.
Shorter reach without raising the bars, and giving more room within the fairing.

Gibson, it is not fine to drill aluminium bars - get your facts right before you post on what is a safety matter with potentially serious consequences!

It took a while, but I figured that out. I simply haven't purchased an RT gauge mount yet. All the ones on Ebay simply say "gauge mount", but you're correct, I need the one with the shorter dimension between the 2 mounting positions. It's crazy that BMW handlebar position options rest upon the gauge mount, but there you have it.

In the works, my friend.

I might have a RT instrument bracket Wobbly, yours for postage cost from Oz. No idea what that is, but my guess would be around USD20? If they're thin on the ground..it's there. To be sure, I should get dimensions to check. That's if I have one, but I think I do somewhere in a box od bits. I'll check tomorrow.

Beemerboff, sorry, You are correct. Renthal warns against this. I suspect even a small sloppy hole with burrs will cause a stress riser as their bars are heat treated and shot peened , I suspect. There are aluminum bars (Woodcraft) that you can drill small locating holes for controls and cut to length. Sorry if I was not clear enough. I still maintain that cutting Renthal bars with a pipe cutter to shorten is fine.

I contacted Renthal and was informed that any modification including a scratch or punch mark can adversely affect the integrity of their bars and cause failure. They rely on surface hardening for strength and stiffness. I am worried about even a rock chip from a truck. I will be removing these bars from my street bike and replacing with steel. For street riding we have a lot more to loose at 60mph on the pavement surrounded by cars than an off road machine. At the time that I purchased my Renthal bars, this warning was not present. Please disregard my post as it is not ok to modify Renthal bars in any way.
