WARNING - GIVI RACK MOUNT

[Stig]

Noticed my topbox seemed to be "wobbling" rather a lot when I loaded it on bike...

Further investigation revealed that both of the rear support bolts to the rack mount have sheared off... leaving the remainder of the bolt in the bike!!!..

Bike has only done 12k.. but I reckon less than half of that with luggage!

Gonna be a fekin pain to drill and re-tap etc..

Pic of sheared bolt..

I had the same problem with my zrx rear brake mount, managed to cut a slot, using a dremmel with a diamond bit and then used a impact driver, came out

I noticed the other day that the bolts on mine were less than sparkling. In fact, they're so bad that I'll have to strip & repaint the rack when I exchange the Givi-supplied screws for stainless

Same thing happened to me this weekend. Only had my 1200GS for 4 months (5,000 miles so far). The right hand rear supprot bolt has sheared off, had the same devil of a job drilling out the broken part of the thread but got there in the end.

It seems that the bracket is at slightly the wrong angle to go into the frame mount without it putting undue stress on the bolt. My rack and fittings were all new and were showing no signs of corrosion so must be down to stress.

Ended up plugging the whole and screwing a stainless steel screw through the bracket and into the plug which is a firm fixing.

Wonder if GIVI know about the problem?

Givi Rack Mount..

The problem (IMO) is the GS frame (certainly on mine) .. The two end "lugs" that take the bolts are differing lengths from the "main welded" area.. this made fitting the rack mount difficult - in the first instance - leading to undue stress on the bolts.. I've since re-drilled and tapped to M10... My bro made up some new Ali spacers to fit on the existing rack.. to remove as much stress as poss. It definately went on better this time...

BTW... I don't think its nec a GIVI issue... I think its the massive tolerances in the frame ends... ( mine was way-out on one side ) and GIVI can only account for a certain amount of tolerance in their pattern..

Note: This issue also came up with Dutch (Motorrad Concepts) with their hugger.. where the GS rear banjo/brake pipe lengths differed quite significantly!!

I posted about this some time ago, the Givi bolts sheared just like yours. When refitting new bolts you need to ensure that the support arms are bolted firmly up against the recess in the frame tube ends, to do this loosen the bolts fastening the plate etc to the rack and do these up last, i even had to bend the support arm (big vice needed) in order to get the thing to line-up properly. Someone else on here posted about enlarging the holes and using larger diameter bolts.

BTW, the broken stubs of bolts were easy to get out, I drilled a hole down the middle of each one, hammered a small screwdriver into them and uncscrewed them out of the frame. The original bolts were very soft so get some good steel ones as replacements (not stainless as these have lower tensile strength)

Every Givi rack I've ever fitted to a bike has been wonky in some way! Qualty Italian engineering

I've the same problem

GivI Rack Fitting Problems

Hi,

I recently fitted a Givi rack and had problems with alignment, this is due to the alignment of the two rear mountings on the frame not the Givi parts which were correct.

During fitting I had to do the following to improve matters and fitting alignment.

1) The left hand plate (looking from the rear) went on fine with no undue stress on the bolts.

2) I replaced the bolts with stainless bolts as I have with most things I fit to my bikes.

3) The right plate was hopelessly out of alignment due to the seating angles and the position of the mounts. To rectify this I chamfered the seating collars by about 5 degrees using a grinding wheel. The arm, if moved to the plate was too long and at the wrong angle and which if just thrown together would have put undue forces on the mouting bolt per the one which is sheared in the original post. I had to grind off about 3-4mm from the post and angle it by a few degrees (done by eye and trial and error as each fittment will be different), then re paint the said item.

When this was done I fitted the arm into place, no undue stress on any bolts and the plate aligns properly and flat, ready to mount the mounting plate.

A bit of a faff on but it shouldn't have any problems in the future.

Hope this info helps.

If Givi had manufactured the unit with a single across the rack plate this would have been a much better manufacturing option than the two plate idea which leads to mounting angle problems.

Givi topbox

Without much thought I asked my BMW dealer to fit a Givi topbox when the bike was in for the 10,000 km service. The service was not at all expensive & I didn't examine the bill until later. I was surprised that they had charged me for one hour's labour to fit the topbox - around 50€ - now I think perhaps it was money well spent?

Noticed yesterday that one of my support arm bolts has sheared. As the mount was supplied and fitted by the BMW dealer I will be looking to them to fix it. Hope they don't start accusing of overloading (it hasn't been) etc.

I've just fitted a plate which I designed and had manufactured to replace the two plates and rear struts supplied by Givi with the Top Box Mounting Plate kit. It comprises of a one piece 4mm. thick stainless steel laser cut plate and utilises the rear support struts (which is a one piece welded bracket) from the BMW top box mounting assembly. The bracket is a much stronger and better engineered component altogether. To overcome the curvatures in the BMW grab rail, I used Spherical Seating Washers from the tooling supplier WDS. The Givi plate now sits atop without any of the misalignment problems encountered by myself and others. Stresses on the rear bolts are now minimal. The Mounting plate and top box now sits approx 1" further back to allow the pillion a little extra room. (Mrs reckons the extra inch makes all the difference!!!!!!!)

Yes looks very good on the bike. I saw it on sunday.

I just fitted a new Givi rack to my bike and it now mounts on the subframe as you have to remove the BMW rear rack completely. It now sits a lot lower than the old style and seems very sturdy.

 

[Ali-bear]

I have the same thing.

Anyone know of a use for the plastic thing that comes off?

That looks a lot better than the old design (which I have). If mine breaks again I'll argue for the new one

 

[Jonny_L]

Yeah that looks much nicer than mine, the older style mount always looks like someone's just plonked it on without a thought towards asthetics (or engineering, for that matter )

 

[Grizz]

Bought new design 1200 rack from SLM yesterday. (£61-ish incl 10% discount )

Guess it will get fitted today, as the rain is not stopping.

Looks very neat, and I hope the grabrails/hand grips work as well as they look.

Also hope it all works with the Caja Sahels in place.

 

[Grizz]

Fitted new style Rack.

Took about 20minutes.

Most importantly, do not final tighten anything untill all the bits are assembled. (Pic below)

I got Nicola, who wanted the topbox/backrest, to help with fitting the actual plate, once the frame was tightened down.

You can see with the topbox in place, and the panniers on, all fit together rather well, and it seems the pannier allows a little bit mpre space behind the seat.

Quality of the whole assembly seems bery good, and the handles are great even with gloves on.

Once fitted, I could not get the monkey off the bike


Tighten only when all bits are located.

Needed to persuade the rearmost points slightly with rubber mallet to get the plate to fit totaly freely.

Comfy seating position, keep in mind, she is a 5'11" lass.

Happy Monkey...
