Topic: Cb550 under seat electronics tray

[jcop550]

I was wondering if anyone has build an under the seat electronics tray, and how they did it. Or if anyone has one they would like to sell.

Hey!
I built a few of those for two 550s... I made them out of a 3mm metal sheet. I have the correct measurements somewhere. Let me know if you need them.
I fitted the starter, lock switch, 8 cell Anti Gravity battery and the whole m-unit system in there.

Check out the photos.

Do a Google search, you can spend hours perusing the different possibilities.

Thats perfect. Looks great. If u still have the measurements that would be great. Did u weld the sides? Thanks

Ill see if I find them the next time I go to the garage...

I cut the sides all the way around and bent the walls up, instead of welding the whole thing. looked much better. I welded where the sides meet after, to seal the box. I also welded the whole box to the frame.

Making a metal box is fairly straight forward. Start with some cardboard and make a box that's taped together until you get the right dimensions for your application. Depends what you want in the box. Mine has everything except some fuses and battery so the box can be less deep. I used 16 gauge steel, welded up the sides and powder coated it.

I'd avoid welding the box to the frame. Cal737 recommended I use "nutserts" or "threadserts". All they are are a rivet with threads on the inside. Put them into your frame and you can use button head allens to secure it.

I made a flat "tray" out of aluminum sheet. Bolted below the tank crossmember with nylon spacers & the rear directly to the frame crossmember. Much easier to fabricate than a box, better airflow while still protected and nearly invisible. With the rectifier/regulator upgrade I was able to mount everything with stock wiring harness except the battery which is mounted remotely below> http://forums.sohc4.net/index.php?topic=153247.0

I too prefer sheet aluminum (1/8", 5000 series) riveted to the underside. For improved cooling, drill holes from rear towards front on a slight angle to aid in cooling. You can paint, powder coat, undercoat or anodize the tray afterwards. Line with toolbox drawer mat to insulate any shorts. Done.

Perfect. I plan on putting a lip all the way around to place in the frame from the top then i can put my seat right over it. Something like cognito moto makes.

The lip is really unnecessary and only diminishes the interior space available. Use some button head cap screws from underneath and you'll be secure, discreet and easy maintenance.

Sounds good. Thanks my man

Here is a current eye level pic of mine with remote battery mount...my project is moving sooo slowly but at least she's on the road.

[jcop550]

Yeah i plan on making mine a little deep to fit a small battery and the electronics, then have the ignition coming from the side of the box. I have a 78 cb550 and my ignition sticks straight up from the tripple tree

You would do well to recess the key behind the outside plane of the tube to prevent your leg from bending or snapping the key off. Just a little extra planning...
