CB1100 Backrest Project

[metalmaven_imp]

Here is my second CB1100 project, a Custom Removeable Backrest.
My wife can't really ride without one, and though I kind of cherish riding alone I figure I better keep on her good side.

So here is a jpeg of my CAD file so far. I am going to paint mine black, probably have it powder coated but not sure. I did the best I could measuring the bike for this, but if it actually fits the first time I will be very surprised!

I will have my laser guy cut out the main sheet metal bracket tonight, and having my press brake guy bend it up hopefully by wednesday.

That is so cool. I love this cad stuff. I always used a pencil for my drawings. Using a computer is just too cool. Some of you guys are so smart. I feel like my dad.

LOL Thanks, I am only 2 years into this cad stuff. Some dudes are just incredible at it. I have the basics down, kinda.. There is a lot to learn. Luckily I get to do it for a job and am learning and collecting a paycheck at the same time. Score!

Very cool! The mounting system looks pretty trick and should make for easy on/off. I'll be watching this with great interest!

Nice! Where were you 2 years ago?

According to the post above yours, he was just starting to learn CAD!

Ha thanks guys! I didnt get my parts cut last night due to material issues, but should be good to go for tonight. I will post pics all along the way. Cant wait to get these brackets cut and bent so I can se how it will fit up this first prototype run..!

P.s. whats with the COLD WEATHER I wanna ride!!!!!

Here is a picture for all interested in the process. This is my laser "nest" of the 2 sets of sides I will be cutting out to start with. Depending on how the forming (bending/press brake) goes, I should be able to make 2 good backrests. Sometimes forming does not go so good so its good to have an extra part or two..

These left and right bracket sides will be welded together and painted to create the look of a solid one piece bracket after I make sure they fit up ok.

Are these lazer cut?

I use an Amada Fiber Optic Laser. Its a perk of working where I do, in a sheet metal shop

Are these lazer cut?

Metal, this is a cool project. Can't wait to see the finished product.

This is great!

Now we just need one for the driver ;-)

 

[metalmaven_imp]

Well I got some brackets lasered and bent up.
Cant wait to get home from work today and see how they
fit!

That is really cool.

This seems like a great idea. I would love something similar. My GF will not ride except in town on a bike without a backrest, however I really dont want it on there all the time like on my other bike.

I have the same thoughts... I am not a fan of a backrest on a bike, it is strictly something that will be there when and only when the wife is there. I am still working out the details on the locking clamp, it will have a balance of being removeable, yet not so removeable that some joe shmo can steal it from you..

Fit up is going good. I have the halves tacked together and a couple bugs worked out.

Are there currently any accessories that latch onto the Hook Bolts (the studs sticking off the grab-rails)?

Do you have any plans to build more of these if it turns out well? If not, would you be willing to share the CAD file so i could have a local shop work something up?

I am not sure what is out there for accesories that attach the same way my backrest will. I definitely plan on making more of these once I get it dialed in. I will probably sell them in my Etsy Store

That is really cool.

Check out this video :

That is neat way of locking.

I'm surprised that there are no accessories yet with quick release for cb1100.
It would be great to have tail bag with driver's backrest for example.
