Oxford Lever Guards & Hand protectors

[OlieL]

I am baffled by this, although I will admit I have never removed the bar ends from my RS (and don't feel like doing so now.   )

The link you provided to the product on Amazon shows an expanding assembly to make the connection inside the bar, and no spacer. The parts you have on the scale do not show the same assembly, just the long bolt. So, I am trying to figure out what is bearing up against what when you push the lever assembly into the bar end, such that it is sticking out too far (and needs a spacer that comes from where?)



Also, looking at the picture of the scale on the left - the original bar end has a short bolt which means that it is being screwed into some threaded hole in a block inside of the bar not too far in from the end. How did you fit the new lever guard past that. 

Anyway, Google "motorcycle bar end spacers" and you might find a spacer to add to the spacer shown ...?

Regarding the equivalency of vibration attenuation - yes the weights seen at the bar end are similar, but while the stock weight is a lump at the end, the lever guard with tiny "sail" attached causes different loads seen by the end of the barn which could cause a difference (reduction?) in the vibration reduction effect. Only way to know is to try it.

Removing the OEM bar ends is literally a case of undoing the bolt at the end. The spacing difference is because the threaded hole projects beyond the end of the grip by a fair amount (maybe 15mm?).  

The expanding assembly bit just comes off and the bolt supplied screws straight into the threaded hole the original bar end goes into. It's a straight swap.  The supplied bolt is much longer than the OEM one (because of the assembly) but I've screwed it all the way in with no problem.  

Having done some measuring yesterday I think an M16 spacer (30mm diameter with a 17mm diameter hole in the middle) will do the job. I have ordered some and will report back... 

Yes, I figured there may be a difference given the different weight distribution. As you say, only way to know is to give it a go! At least the steel spacers I have ordered may attenuate any difference by a small amount. I doubt they sell M16 spacers made of lead
