The problem of the rear view in RS mirrors came up in another topic. As soon as you add anything to the pillion seat (passenger or luggage) your rear view just about disappears. One solution by a member on this forum was to fit handlebar end mirrors but although that solved the problem, it meant that the bike was now a bit wider. Fitting mirrors to the usual mounting points was a bit of a no-go because it restricted the steering lock when the mirror stems hit the fairing. I'd been thinking of a way around this for a while using the original pod mounts, but the thread made me stop thinking and start doing.

I dug a piece of 25mm x 3mm mild steel out of the bits box and used the pod mount to work out the hold spacings. I allowed 40mm from the top of the mount and then a further 25mm for the fold over and mounting hole. This, I have to say, was the easy bit.

The not-so easy bit was curving the bar to match the pod mount.

The rubber part of the pod mount has three standoffs in it. The two that the bolts pass through were shortened by 3mm - the same width as the new mount.

I cut a piece of 4mm thick rubber to go around the pod mount and cut it out to match the new mount.

Like so:-

The rubber spacer was glued to the original pod mount. I hit (literally) a real snag when bending the top mount. 3mm steel does not like being abused with a BFH in a vice. It split along the outside of the bend, so I ran a bead of weld along it and reshaped it.

The finished product:-

It's got to be enamelled yet but I needed LFB for work! The angle isn't as bad as it looks: it's due partly to camera angle and partly that LFB is still on the main stand.

Only the righthand side to do now. Very Happy

Those damn mirrors cost me a $150 summons for failing to yield for an official(state police) vehicle.

A badge heavy young punk of a State Trooper didn't like that I didn't instantly pull over for him when he suddenly came up behind me during rush hour.  That he was so close that I couldn't see him in my mirrors didn't get me out of the ticket. 

Even when you don't have a pillion or luggage strapped to the seat there is a huge blind spot to the rear.

Having ridden to work, I can say that the mounting angle is as bad as it looks. Look out for the Mk.II version coming soon...

Gryph I have no blind spots with the addition of the bicycle bar ends. But as Dai pointed out they do make the bike wider. However even though it is now legal in OZ to lane filter I only occasionally have to swing them in.

Regards Martin.

Okay - the Mk.II version. In truth, the only difference between these and the Mk.Is is that the top mount has been blattered by the BFH at a different angle. They are now only a couple of degrees of horizontal when LFB is on its wheels and I'm sitting on it. The paint is black tractor enamel.

First use is probably going to be the Dragon Rally next Feb.
