Before getting the Tiger with full luggage I had soft luggage on a 650 Strom,,, do not do it. by the time you have secured them and then put the waterproof covers and found how difficult they are to pack anyway !!!just forget it.. I had similar problems to you on the tiger, enormous topbox ,, tall bike ,,, short legs etc,, I now just pack less and stick to side panniers and I have had the bike lowered,, job done
