I guess it depends on where one lives, but over here, winter = D.I.Y. season.
I've got the OEM Traveller hard side bags, which are great for anything that's expensive or heavy. But to haul a sports bag full of clothes or possibly a tent, one really needs a luggage rack.
I tend to visualize in 3D beforehand, it's cheap prototyping. Have a look at the images.
Obviously, I didn't draw the second 'leg' there, and the bottom mounting bracket needs a little bend, but hey, some things are harder in CAD than in real life, and vice versa.
4 Bolts hold it in place: the 2 rearmost ones under the seat that mount the passenger grab handles, and the 2 between the rear fender and license plate holder. The frame for the kawi side bags (visible here: http://www.kawasakiversys.com/forums...9&d=1257794452
)also mounts to the license plate holder, so it should all form one big triangulated box section.
It's 300x300x160mm, and I hope to make it out of 16x1mm chromoly tube - the same as the kawi frame.
The cool thing about these CAD drawings is: you can print them out 1:1 on sticky paper, make cardboard templates, and check for clearance before* you start cutting up metal.
Any other cool winter D.I.Y. projects out there?
