I carry a fair amount of weight in my top box. I seem to recall you could purchase a strengthening metal bracket?

Any ideas or have one to sell me

Thanks
 
I don't know which top box support you need for the box you're looking at, but I've fitted the sw-motech support and the Givi SRA 5112 top plate with the standard rear carrier on my 1250GS and it all fits together nicely. If I remember correctly, I did have to get some slightly longer screws than were supplied with either of the units.

Any chance you could post a piccy of how it all fits together please?
Somebody asking a similar question on here regarding the strengthening bracket etc etc.

I don't have access to the bike until after 8 July, but I'll try and do so then, if you don't mind waiting that long. I downloaded the fitting instructions from the Givi and SW Motech sites before I bought the kit and worked out how to fit them all together. I made myself some sketches so I'll try to post them as well. It wasn't at all difficult.

Unfortunately I don't seem to be able to post pics or other attachments so I'll try an describe how I fitted them.

Please refer to the fitting instructions for the Givi SRA5108 top plate (ink: https://media.givi.it/XN-Prodotti/istruzioni/SRA5108.pdf) and those for the SW Motech reinforcement (link https://sw-motech.com/cosmoshop/default/artikelpdf/gpt_07_782_18000_b.pdf.)

I'll use the item nos listed in the instruction docs with prefixed with either G, denoting the Givi item no or S denoting the SW Motech item no. So, for example the Givi SRA5108 plate, listed in the Givi parts list as item no 1, I will call G1, etc.

I worked out how to put them all together by reading both sets of instructions and working out how they would fit with each other. The manufacturers' instructions give full details of how each part should be fitted individually, including using loctite and details of any required torque settings. The notes below are based on my memory of how I put everything together on my bike. I can't guarantee that I haven't made a mistake so it is the responsibility of anyone trying to do the same to work out for themselves how to do it properly and safely. I'm afraid I can't take any responsibility for how anyone else chooses to assemble the components or for any consequences arising.

Anyway, this is how I did it:

1. Follow the SW instructions to dismantle the original BMW rack, and to fit thereinforcement unit S1 into the lower part of the original BMW rack..
2. Fix the the lower part of the BMW rack and S1 to the bike using bolts S2 and washers S3, and use the original BMW bolts through the front grab handle mountings.
3.Fix Givi part G2 to at top rear of BMW rack using bolts G4 which pass through holes in plate G2, through G10 spacers between underside of G2 and original BMW carrier. and then through the matching holes of part S1 and are fixed underneath using washers S6 and nuts S5.
4. Bolts G5 go through the front holes on plates G1, through spacers G10, then through the equivalent holes in the front of the original BMW carrier and are are secured underneath using nuts S8.

You may find that bolts G4 are not quite long enough. I replaced them with countersunk M6 screws x 50mm long (I think).

Hope that is of some help. My apologies again for not posting pics.

If you are only putting no more than the 5kgs in weight, you will be fine, seems the Op,s put a tad more in their boxes...

Mmm ive no idea how much is in there, usually only a few spanners and dusters, tyre pressure guage, drinking water, wet weather leggings, Yoko shell jacket......oh maybe on second thoughts ?
 
Hi Db. When I purchased the SRA5108 (not SRA5112 as I mistakenly identified in my post above) there was a warning on the Givi website (and also on other seller's sites) stating the maximum safe load is 6kg! This seemed ridiculously low to me so I contacted Givi UK who confirmed to me by email that the 6kg limit refers to the safe maximum load that can be carried in any top box fitted to the SRA5108. This is still ridiculously low, but that's what Givi say. It does mean that the safe maximum load of the plate itself is actually about 12kg; ie 6kg contents plus about 6 kg for the weight of a top box. I don't think SW- Motech make any statement about what the safe maximum load will be when their reinforcement support is fitted, but I felt that I could afford the extra cost of £30 or thereabouts to give a little extra strength, albeit unquantified. I don't think it can be very much of an improvement because it is bolted to the bike with only the same two bolts that fix the original carrier.
PS I'm loving my 1250GS TE Exclusive as well.
 
It's meant to be fitted under the case! :D

Well for the sake of £35 ive bought one and will fit as soon as it arrives. Its not a big job and it will give me peace of mind knowing that my topbox wont be flying off into the wild blue yonder, unless ive crashed into a hedge lol.
