Been thinking of making an undertray for my 1998 CBR F3.

I'm not bothered about the light section that can make the shotgun look, just to cover all the gubbins under my seat, and also to hack off the rest of my reg plate holder.

I'm thinking of buying some 5mm A3 sized clear perspex for £7 off eBay, cutting it to size with a dremel, vinyl wrapping it, then bolting it down.

I have a bracket already that my plate can go on to, and also the indicators, this can then be bolted to the undertray.

I've never seen this done before and it seems so simple.

Anything I should watch out for or change?

Cheers

On CBRFORUM someone did something similar with sheet steel.


You'd be better off just using black Delrin sheet rather than vinyl covering perspex. Delrin is easy to shape and if you are happy with black or white you don't need to paint it Thumbs Up .


Will try and find the undertail thing in a minute.

Can't find much of that material you mentioned, the stuff I can see is about £30 which is pretty much the price of an undertray.

I've seen this which might be better, it's already in black but only 3mm, not sure if this would be solid enough...

3mm seems a tad thin to me.


The material itself will be alright though if you can find it a bit thicker.

What I would do, but am in no way suggesting you should do Wink is nick a road sign and use that. They are normally 3mm sheet aluminium and would be perfect.


Also consider sheet aluminium sourced in a more honest means, it is fairly easy to shape with normal hand tools and would be strong enough and resist flexing/cracking etc.

Ha I like your style!

I think i've found the page you mentioned https://cbrforum.com/forum/600-modifications-43/diy-undertail-96-f3-108156/

I would bolt it down the same way but I just have one problem...

If I bolted it the same way this guys done, you are you supposed to unbolt the seat?

You would also need the seat off in order to attach a nut on the other side.

Hmmmmmmmm!
