3 Pistons bar end mirrors fitment problems

Yep, you can get it wrong even with genuine Triumph bar end mirrors, there are (at least) two different versions of bars with different inserts, one has a larger thread than the other. I believe some have managed to remove the inserts to allow fitting of the expanded collet type, but I suspect it's not easily done without risking damage to the bars.

 

I was aware of this before i fitted my 3 pistons so fitted some new bars as well in red just for a change and they are a little higher with a bit more pull back for my short arms lol

 

I came across the same problem. I locked a bolt init n put a massive pliers onto it and pulled it AND only things happened was my bike almost toppled over. I ended up getting longer bolts n washers n it's all good now.

 

They are Rizoma fat bars, cheaper than Renthal and come in 3 different rise heights and colours. I have the 50mm rise bars and i paid £60.00 as Moorespeed will give a little discount if pushed

 

And a choice of black silver or red

 

I've managed to fit the 2016 OE bar end mirrors to my 2014 ST - Quality, usable, genuine triumph mirrors for half the price of the triumph accessory brand items that look nice but I found way too small to actually work.
The mirrors are approx £35 each + a couple of aid for the pinch bolt - inc vat about £80 odd.
My buddy who's an meticulous engineer made up top hat bar ends that are required for the mirror clamps to fit to - stunning over-engineered quality, way better than standard.
I'll post a couple of photos and if anyone is interested he'll do a pair for £40.

 

Just got a set today myself. Lucky for me I already have a huge box of spare bolts lol... only bit I can't see what it'd possibly be for is the metal plate with a hole in it?
