I've got krausers on my airhead, and I have an extra set with mounting brackets that I'm thinking of either attaching to my 750K5 or selling. Those rear turn signals need to be moved.
... hmmm, sorry but I really don't like the looks of Krausers on a CB750K while I love them on an airhead. Besides, reading all of you guys great advice, I have come to the conclusion that soft (or semi-rigid) side-bags is the way to go for 2 main reasons:
PRO:
1. Protection:
In case of fall, w/out cases or with hard cases, the whole energy is transferred to the frame/support structure. Soft bags act a bit as a bumper.
2. Looks:
This is subjective and, apologies, I only like the Shoeis. All others would ruin the bike's look.
CON:
1. Rear back support:The hard rear/top case doubles as back support and is better looking than a sissy back rest
DRAW/EQUAL:
1. Detachable: there are both hard and soft detachable bags.
2. Rainproof: there are both hard and soft rainproof bags and, depending on year/model, both hard and soft options may need additional internal or external water-proofing.
3. Rear lights: both require repositioning.
On my trip last summer, I did without side bags even though I had a used pair of ballistic nylon ones. I went with a large tank bag in front and a weather proof duffel bag behind me. Nothing stuck out towards the sides so it was pretty good aerodynamically, and I could lean back and get a bit of support from the duffel.
This is by far the best solution but I can't use it because I travel with pillion (wilfe).
