Custom rear top mount

[jrubicon]

Since nobody makes a top rear rack that mounts above the passenger seat, i decided to fab my own. The only rack i see mounts behind the passenger seat.

I started with a Givi BMW mount, I received the mount but it was made of steel and actually siginificantly heavy.

I am fabbing my mount out of aluminum 4mm 6061.

 

the edges of the mount still have to be bent to add strength.

still under construction....

Good job on the fabrication, looks good.👍

Great idea. I’d love to hear whether you think it makes a big difference being mounted more towards the centre of the bike. I dislike my topbox being slung so far aft and up and I “think” it affects the handling, but it may be a lot of false perception.

mock fitment, not too happy with it, i want the box more in an angle but the angle of the plate is determined by the 10mm bolt in the back. 

 

off to powdercoating

Nice work. I did something similar for my aux fuel cell using 80/20 tubing. Having it mounted farther forward provides considerably more support and has almost no effect on handling.

Looks like a Viper to me.

thanks all, im a little dissapointed in my fab, I should have done my homework more. the monokey system doesn have a case smaller than 30l,

i was hoping to use a small case sometimes, the 36l case is too big. i may bolt on a sw-motech adapter so i can use the monolock boxes which have smaller cases like for one helmet.

ya dodge viper

I think it looks so much better over the rear seat like you have it than way out back past the brake light.  Good job.

the place that supplied the aluminum also bent it powdercoat it, $30 for 4mm alum 12x12, $20 for bending. i cut it to shape n drilled, then i dropped itboff to machine bend then more fitting then dropnoff for paowderdcoat, they didnt charge to powdercoat, its a textured powdercoat.

i did spend 82$ on the bmw mount which served as a template, i stole the tubes n mountbkit which i welded to work for me
