three of the four "arms" that hold the screen on have broken (almost lost the entire screen on the M25!)


does anyone have any advice where i can buy them? any fixing tips?


thanks

This is the BMW parts diagram.



MotorWorks sell the upper (#5) and lower arms (part of #9),  the latter is not available separately from BMW.

i see


that's £200+ in parts then


ouch.

Looks like only one lower arm is needed.

This video shows how to replace the upper arms, https://www.youtube.com/watch?v=VrHAGl3NUj8

Looks like the headlight panel will need to be removed to access the lower arms, https://www.youtube.com/watch?v=Fu9TzwR4D1I

i might as well replace all four though

The upper, https://boxer-upgrades.webs.com/apps/we ... ow/3658072 and lower, https://boxer-upgrades.webs.com/apps/we ... ow/8199971 arms are available in stainless steel, with 15% discount on all four.

I've got the upper ones on my 2012 Camhead, supplied and fitted by a friendly RT owner.

Almost lost the entire screen.

Is it an aftermarket screen, if so, which one.

Mine is a Ztecknik VStream.

[ds99]

yes, it's a larger Cee Baileys one


i have ordered 4 arms from here:

total cost (inc shipping)... £110

That's a good deal, half the price of MotorWorks and all in stainless steel.

Will be interesting to see how long they take to arrive.

To all who have extra-wide screens, I'd recommend replacing at least the upper two with stainless steel arms.  I've lost two of the OEM's on my hexheads which broke just as yours did - at the narrowest point where it fixes to the screen, and it'd be dangerous if both failed at high speed.  They're made of what looks like cheap pot metal aluminum which a welder told me are unworkable.  Shameful the way BMW's cheaped out on this piece.


Have they changed these arms in later models?

"The support arms on the 2014 and newer RTs are much stronger".

I had a Cee Baileys screen on a 2007 Hexhead and 2010 Camhead, at speed, found that the downforce was so great that the motor wouldn't drive the screen up & down. Decided to ditch it and return to the stock OEM screen. Fortunately, when purchasing the Ztechnik for my 2012 Camhead, the nice man included and fitted the s/s upper arms too. I wonder if there is any correlation between aftermarket screen types and arm failures. Has anyone had an arm failure with a standard OEM screen fitted.

Did the OEM upper arms break with an aftermarket screen fitted, if so, which screen was it.

mine is a 2007 bike, i got it in 2016 with 35,000 miles on it.


i replaced the OEM screen with a bigger Cee Baileys one when i got the bike.


three of the screen support arms have just broke at 54,000 miles


a lot of the miles i have done have been at speeds of 60-80 mph with the screen about 30% raised

[ds99]

i have read on other forums that the screen arm failure is more common with aftermarket screens

this would make sense as a taller/wider screen would put more stress on the two upper support arms

my screen almost departed the bike at 70 mph when three of the arms broke!


i guess it also depends how far up you have then screen when riding, the higher it is, the more stress on the arms
