I have finally decided on the Givi E370 topcase after reading about topcases until my eyes started to bleed! It looks like the best choice for my daily use as a commuter.

My question is about mounting this directly to the rear wing. I know you can buy the heavier duty mount but I only need the case for light weight commuting not long trips. The Monolock comes with a nice mounting plate but I want to make sure I secure it properly to the SW. I am handy with tools once I'm pointed in the right direction by someone who as pulled apart the back of their bike. Can anyone give me some tips to make this go as smooth as possible? Thanks in advance for your response. David

The holes are already 'marked' on the Silverwing rear spoiler.

Remove the said silver bit - four bolts - take off the plastic undercover and you'll see raise tubes.
Drill through these, attach the Givi plate, reassemble and Bob's your uncle!

There's a pictorial of how to do this although it shows drilling only two of the holes, those for the Givi backrest. You can't go wrong if you follow it.

I bought a brand new drill-bit but it wasn't really necessary.

I'll find the link to the pictorial if no-one's beaten me to it.

Thanks for the link Mike! It doesn't look like that should be too difficult. Once again, thanks to Jeff for posting all the pdf guides to working on our SW. I am quite sure Jeff has single handedly reduced the use of 4 letter words by thousands.

Follow-up question...Is the rear wing flat enough for these mounting plates? The Coocase comes with the same flat plastic mount as the Monolock, says it needs to be secure to a flat surface. Has anyone had to use spacers to the the mount to fit correctly?

On mine, the metal bits which sit on the rear wing and on which the Givi plate sits have no spacers - they sit directly on it - unless they're so squashed I can't see them any more!

Givi make the system for the Silverwing so you need have no worries.

Incidentally, I discovered yesterday that Givi make the boxes which are branded 'Honda'.

I'm not buying the Givi mount since it is optional on the monolock boxes. The monolock comes with a universal mount which looks like it should fit directly to the rear wing and sit flat. Here is a picture of what I am talking about:

Mm. Not sure about that.

You might need four spacers/thick washers or two thin strips of metal or wood (ash, for example) running fore and aft to allow for the slight curve from side to side of the rear wing.

I think also you may need longer bolts, too.

Sorry to be a bit vague but I can say definitely the rear wing is up to the job.

I really like the mounting plate for the Givi boxes, as it allows you to use the mounting plate as a carrier when the top box is removed. I can bungee 2 large folding camping chairs to my plate when the top box is removed. I can also carry my 2 piece fishing rod with me as well. I have a passenger backrest installed with the mounting plate. Do you carry a passenger often?
