On Ebay there are mirror extenders for just about every type motorcycle out there..MOST are $14 TO $20 A PAIR..they extend up to 2" and give a greater range of motion for more mirror position options..

except thay all say "not compatible" for our bikes..but why are none compatible?..
I found one...and they shipped from canada..was a 1" base block type and cost a bullshit almost $50 FOR ONE ..I would rather not have the block type extender anyway even if it was cheaper to buy.

So why wouldnt one of the GENERIC 8mm or 10mm extenders work...parts fiche doesnt even describe what the big single bolt on the base of the mirror stem is...
anone know? anyone tried or have an extender on that works with our bikes?

Those are the Block type extenders I mentioned above...tho these are a little bit cheaper..they are still almost $70 USD for a pair...and only raise the mirror 1".....note quite as great as the extra added mobility and 2" extension as the $14 generic extenders will do as this example below...if they can be made to work somehow :(

The website doesn't say ANYTHING about what these fit!
I would "Ask Arnie".

I have only seen 8mm and 10mm types of this kind...look long enough on Ebay and you will find a page with compatibility options on it for these types...so far they have all said "this is not compatible with the 2011 CBR250R"

so my original question was and still is..is the big main bolt on the bottom of the mirror stem an 8 or 10mm..and if so? then why wouldnt these work?

The microfiche does not show that screw alone, just part of the mirror assembly.
You will have to take one out and measure it.
once again..I defer you to the original post where I already stated this about the parts fiche and asked and hoped someone already had done this and has this information so I wouldnt have to do this

You've been there - why not provide a link?

Why does it matter? Do you think I am lying about it? LMAO
ok..here ya go..here is one of many examples..and they all say the same thing about our bikes.

$15 & free shipping - it sounds like a cheap experiment.
very true...I agree with that statement wholeheartedly....the mirror bolt is 8mm....I have ordered a set from a seller after a bit more detective work and lots more searching and will be the guinea pig and try a set out..about $18 total
...they extend the mirror out 2 1/4" longer than stock and 1 1/2" higher than stock..so hope they work..the short mirror stalks have been one of the more aggravating things about the cbr to me since the day I bought it

if they do work I will post the link to the exact seller I bought them from .....they are supposed to arrive next tuesday by usps so should know something by wed if they arrive on time (its not the one I posted above for the example)

I never would have even considered mirror extensions if you had never brought it up.
Everything about this bike is so much more user friendly than my BMW R65 that I had owned for over 30 years, it is hard for me to understand why people want to mess with things like that great headlight.

But yeah - I've been playing with my mirror adjustment and I have not been happy.
I will probably join you in this experiment!

Hello,

I bought the "mirror extemders spacers" on eBay USA. They work and do indeed help. But they are no so good like the advertising photos show. Still, I'm a big guy at 6' & 240 lbs. It takes an effort to see directly behind the bike.

Peace Out

so you bought the " 1 inch block type" extender? I can tell by just looking at them they just don't cut it....thats why I wouldnt even consider them even if they were cheaper..which they arent

Success....they work great....can see behind me with ease..just the ends of my elbows visible in mirror now....a tad bit of vibration revving up thru gears but not enough to outway the positives

BUT...and there always is a BUT....
the mirror bolts were put in with the most potent loctite there is (blue loctite) and they were obviously never intended to be taken out again..So I tried just about everything on the first mirror till I finally got it out...I will cut to the chase and describe how I took the 2nd one out, which took me 5 minutes or less.

take of mirror assembly...put in vise...drill out bolt thru top, going down 3/16 to 1/4" deep..tap in square punch...twist...this will break/sheer off the top of the bolt (this is a good thing..you want it to do that) or you could just hit it with a hammer n flat head screw driver to brake it off..really soft cheap metal screws........... top mirror stem will come off then....catch it before it falls and breaks.

you will then have a 1/4 inch or so of bolt exposed that will still not back out even with clamped on vise grips (I tried)..you must heat it up to break the loctite bond..I used a torch for less than a minute...remaining bolt then extracts with ease.
(yes, I tried heating the bolt for a very very long time on top and bottom before doing any of this..it still just stripped out)

I went to Ace Hardware..bought 2 button head- M8X1.25 bolts...1" long..1 1/4 will work too..reinstalled mirror WITH mirror extenders.....


vise did scratch my paint a tad..touched it up with a can of black spraypaint a few minutes before reinstall



installed ..still have my denali's on mirror stems

I did manage to remove my first OEM screw with no damage (thanks to your warning).

I put the assy in my vise with it's plastic guards and tightened it well.
Then I applied heat via my plumbers torch (I need one of those pencil torches) to the bottom of the screw (visible on the bottom of the mount and to the head of the screw as well.
Then I put a small dab of valve grinding compound on the tip of my allen socket and put it on my big 1/2" breaker bar. It came free!

The VGC helps the allen key get a better purchase on the fastener.
