one thing which is becoming increasingly obvious as I ride the bike a bit harder, is high-frequency handlebar vibration - especially the right side, which I think is probably attributable to the throttle twistgrip/handlebar fit. I'm thinking in terms of a handlebar weight, or possibly a bar-end mirror - anyone have any thoughts on this?
Back in the day I put 100 or so elastic bands round my throttle grip. Worked a treat. Do they not make anti-vibration grips for your bike. I had some on my Harley and they worked very well.
My Sportster has the "coke bottle" grips and they work pretty well. I did think a handlebar mirror might be worth having in any case...
Had a similar problem on the bonnie. Fitted some bar ends mirrors and this seemed to sort it out. If interested, fitted some from https://ironhorsespares.co.uk/
That's odd, I've had both alloy lightweight bars without bar end weights and now back on std heavy bars with bar ends but non should vibrate as mine never have. The only thing I can think of is an unbalanced front wheel or some feedback from the calliper
Try some of these; http://www.ebay.co.uk/itm/Grip-Pupp...041193?hash=item4af4775529:g:QdoAAOSwY0lXSqgQ They made my Triton almost rideable
The foam sleeves seem to work very well! Bought some on Amazon and fitted them, first trials seem to work pretty well at suppressing the tingle on the right hand side. I'm sure this is due to the fit between the twistgrip and handlebar, which seems generally rather loose.
Probably, but I don't have any other option. The twistgrip feels quite a slack fit, and I'm sure that's the real problem; but I don't know enough about these ride-by-wire throttles, and I'm not taking it apart on spec.
I agree. Triumph did not design the modern Bonnie to loosen fillings like its 60s namesake. If you have any appreciable vibration I would be checking frame and engine bolts to correct torque having first balanced the carbs/throttle bodies. Treat the cause not the symptoms!

I already did that, when the right-side footrest loosened itself (which I gather is also quite a common problem). I took most of the slop out of the mounting with a couple of spring washers, and haven't had any issues with it since. The bike really doesn't vibrate at all, to speak of. It's just the right-side twistgrip, which makes itself felt after a while. If it was a "proper" throttle I'd just dismantle it and fit a nylon twistgrip barrel, well fitted to the bar with a light smear of grease, which usually cures tingles of that sort, but I don't know about these fly-by-wire contraptions and don't feel like finding out.
Strangely I have the same issue with my 2014 T100, when stopping after an hours ride I have a tingling in my right hand despite consiously trying not to grip too tight ( ooh err mrs ) - replacement soft grips? Anyone know of any?
The foam grips seem to have tamed the vibration nicely, although I haven't yet been on a long ride (over 25 miles) Just as well, seeing as I can't budge the screw holding the right-side handlebar end in place.. there are a number of threads on Triumph Rat forum about this, seems to be a common problem on the later air-cooled bikes.
A good old boy fix fill the bars with sand or lead shot ! The weight and loose material acts like a shock absorber " Cheers capt.
