Rear rack like the Kawi rack and backrest
« on: February 02, 2014, 01:37:31 am »
Has anyone found a rack like the factory rear rack with a backrest. I can not find anything to mount a pelican case to. the little rack under the cover is not big enough or where I would like it, I would like it over the seat. I only ride 1 up so the pillion is luggage space going to waste.  :motonoises:

What you really want is the adapter that is used to mount the rack or backrest. You could then fabricate a support for the Pelican the adapter just has some bolt holes, so it would be fairly easy to do this. Usually adapters are not sold by themselves, but you may want to keep an eye out.
I don't know if they're still available as new.

Thanks Jorge, what does the adapter look like? I have some fab skills, more importantly I have friends with mad skills :).

Jay, they are made up of an aluminum casting and two cast aluminum  lamps. It clamps to the hand hold rails towards its rear. I did a qhick search and there apears fo be a seg on Ebay:

Adapter? Makes your own. There are 4 perfectly good bolt holes where the factory "luggage rack" (the little plastic thing) bolts down. Just fab a mount to that like I did. No need to try to clamp to the hang-on bars.

My first trunk mount was 1/2" box aluminum bolted together (had plans to get that welded,then made a box from aluminum plate instead). It was very sturdy with little flex (box shape made it more rigid).

You could make a nice, simple framework from this box aluminum, have it welded, then mount the pelican to that. Add an inexpensive generic backrest pad from somewhere like motorcycle superstore and you'll be riding in comfort!

You could also make it a quick release by using this setup:

Thanks Jimbob, how tall did you make your rack? I souls like to get mine up and over the rear part of the seat. What kind of weight is reasonable if I build from the littlr self under the cover vs something off of the passenger gab handles?

Jay,
Here are some photos of a backrest/rack set-up I sold some months ago.
JimBob's comments are accurate - you're better off attaching to the bolt holes that the useless OE rack mounts to. They are very sturdy. In addition to the benefits of those four bolt holes (directly into the rear sub-frame), you can see from the photos that fabbing a clamping frame would be somewhat difficult; you would need to clamp the grab handles tightly, and with a complex contour - not the easiest thing to make.
The side view is probably the clearest view of what the clamping end looks like. The adapter is basically a U-shape, laying down, with the open end forward.

Thanks for posting the pictures, I think I will look at the rear plate option and keep an eye open for a used rack. The contoured are why they are cast and I can not cast solo of to the design table to see what I can weld up.  >:D

Good job on the pics, Jorge - they really show how difficult that approach is (for the "factory" rack/backrest it makes sense, since they already had all the measurements). Making that yourself wouldn't be easy/simple/fast.

I don't have pic of my old bracket (I'll look...may have one somewhere), but it was just generic 1/2" box aluminum you can buy at Lowes. If you bolt through it to the subframe with those 4 bolt holes in the back it'll be VERY solid. Once the pieces are welded (sorry, heli-arc'ed), there'd be very little flex. It needs to be a base for the case with some structure to stand above the seat - pretty simple shapes really, kind of a rectangular upper section and a trapezoid lower (since the bolts aren't in a square, but rather a trapezoid arrangement).

I made my own rear rack out of a 1/4" thick aluminum plate. I followed the outside contour of the factory rack and mounted it with four bolts and spacers:

Just came in from the garage, I think I am going to build a rack that is about 5.75" tall from the factory spot. I believe I can make a small storage area and have a multi purpose rack that adjust to put a backrest in either the rider or pillion position. I need to grab some tools the next time I am home and star welding.

Sounds promising.

The tricky part will be making it rigid when it overhangs the pillion, while also making it a simple change operation. It'll require either a sliding or rotating mechanism (with the pivot at the forward corner of the case). I'm a fan of not requiring tools to change such things, so like to look aorund for existing contraptions that can be modified to fit.

This would require a sliding drawer/shelf type mechanism, but one that's very rigid to handle the dynamic load of 15 lbs bouncing down the road.

McMaster is a good reference for stuff - they usually charge a lot and have shipping costs, but they have EVERYTHING.

Something like this may work:
http://www.mcmaster.com/#drawer-slides/=qmuo6w

You can get the "standard" class of slide at Lowes for like $15/pair or less. Just never lay these flat - they only handle load when placed in their proper orientation. Laid flat they'll bend.

Take pics of your progress, let us know what you come up with!

Those are called "bungie buddies". I don't have the means to search for who has them right now but if you Google them you can find them. They are extremely strong and durable, very well made.

Also check out strapworks for all sorts of nylon straps/hardware (plastic and metal). Prices are reasonable, shipping seems ok too.

Made a simple plate for a small top case out of the cutting board stuff   It works fine but I am going to build a metal rack when I have more time to tinker. I will keep this updated but it may be a few weeks.
