Mirror Shake and position

Post by Kool1290GT » Sun May 07, 2017 1:36 pm

Hi Guys,

Traveling at highway speeds 80kmph and up its difficult to use the mirrors, they shake quite a lot is anyone else sharing this experience? Also, I can't seem to have a clear view of what is behind me without moving slightly left or right, or tuck in my arms to clear my arm/shoulders in view. I have spent some time attempting to adjust this. The dealer bolted them on tight, so before I loosen the arms thought I would check in and get some feedback.

I have had the same experience. Has been my biggest problem with the bike. The vibration in the mirrors was reduced when I installed a decat and intake but still existed in 5-6K rpm range. I noticed a big improvement when I installed a PCV with a map from a 1290r with similar mods. I can actually make out what something is in the mirrors at that rpm.I am just starting to tune with a Autotune so hopefully I can get rid of it or reduce more. There is a EPA sticker on the frame of my bike that says they test for sound at 5250rpm. I am guessing that is where they close the stock exhaust valve to pass that test? I have removed that valve with my mods, but wonder if the factory tune is tweeked to accommodate this?

Yes, combination of poor mirror position and vibes results in poor rear vision. If I am concerned that a vehicle behind me 'warrants' a second look I press on the mirror with my finger to get a non blurry look. Not ideal but not a huge issue IMO.
S1r BMW was worse at certain revs!

Agreed, very small issue. The bike is so well done, its the only little problem to deal with. Well....that and a number of people that ask me to pull over so they can ask questions about the bike. :lol:

Thanks guys, seems like a few of us have the issue. Are there others that do not?

Mine does this, the right mirror is worse than the left however I had a XR and that was 10x worse.

My matey drilled a very small hole in the mirror back and filled it with silicon and that sorted his mirror vibe .

Mirrors are still the same mirrors from 2013 Ktm models maybe even earlier so they are vibrate and they also give you negative pressure on the motorway.

Bugger me......it's a twin and it fuzzes the mirrors at certain revs (sorry - no disrespect intended) to state the bleed'n obvious.... :lol: I can still make out a highway cruiser from way back in the distance so they work well enough and give a good field of view. Maybe there are some accessory ones that might fit various elbow's and body shapes better, but mine work fine for me.

The Ducati DVT1200 I rode a month ago while it's owner was laid up recovering from prostate surgery had worse fuzzing in it's $36k mirrors......and I've removed the bar end weights from my GT to install the Acerbis hand guards - so you'd expect my GT to be more vib-ie than most - but it isn't - go figure that.. :o

And before you have a go at me MrTkr......I've just stated the facts, not my opinion. Here it is again - my mirrors are fine - now go and buy a 1290Gt dear readers - they are good.....no wait.....they are fekin great..... :D

I was out riding mine today, and purposely looked through the mirrors to see what you guys are talking about in regards to vibrations, sure mine vibrate a little, but in 6th gear at 110 kph, i could make out a car behind me by 150 meters easily, the big twin has a more coarse vibrate, typical big twin, but the mirrors are fine, i much prefer the coarse vib of a twin, than that fine buzz of an in line 4. i did notice when i removed the O2 sensors the bike felt smoother under 5500 revs than previous. funny thing i have noticed is when new there was a vibe through my right foot i think, but after 6500 Ks its totally gone and the bike feels a lot smoother. Been riding in sport suspension mode with luggage, bike steers so much nicer, tips in beautifully now, that added rear preload certainly helps.

Hmmm good point on the break in. I only have 1000kms on the bike so perhaps it will die down as usage increases. My other bike is a 2012 Vstrom used for off road and camping, which is a V twin, the mirrors do not vibrate at any speed. The bars on the GT dont vibrate at all so... im thinking its the design of the mirrors perhaps or the bike needs to break in a little more. I will let the bike age a little, if that does not work, will swap my Aprillia mirrors on the Vstrom, or try the stock Vstrom mirrors on the GT and see the results.

Again, not a big deal at all, but if it can be improved why not!

its not a big deal on motorway , its a deal breaker in the city where you really want to see whats going on behind you. i never have a problem when i used to DECAT the bike and use power commander 5 but now i put everything back as original and my mirrors buzzing like crazy again but i am happy at least the bike is quieter and neighbors are happier :)
