Custom Rear Mudguard Experience - Hugger Style?

[1sttimer]

I have a CB175 cafe without the stock welded-in mudguard that I would like to add a simple hugger-style rear fender to. I'm thinking of buying one of these:

and cutting it approximately at a 1/3 of the length and mounting it on the swingarm next to the pivot. Just looking for some inspiration, examples, people to bash the idea or improve it...lemme see it.

There's also these things I could adapt but I think I'd like it to be a bit bigger. I'm sure vibration will come up as an issue the bigger and heavier the unsupported "beam" becomes.

Maybe something simple like this...

I plan on doing something similar, but I am going to get a front fender with struts and mount it to the swingarm with the struts attaching near the axle.

I don't suspect you could make the fender very big without struts without it cracking near the attachment.

Get a piece of 1/8" thick, by 1" wide flatstock. Bend it ove a pipe or something you have that will work until it matches the radius of the rear fender. At the base (where the fender will mount to the swinger) bend it 90°. Weld it to the underside of the fender. Figure out your attachment plate set up and make sure one bolt goes through the "tab" created at the base. Strutless, plenty strong rear fender that will stay put.

Awesome man. I'm trying to envision this in my head. I may go a "bolted on" route instead of welded but that makes sense to do it that way.

i made a hugger our of fiberglass. Cheap and easy. I made a fiberglass copy of the original rear fender, trimmed it down to the desired shape. Then make a platform for it and trace the profile of the swing arm.

This was a pic taken early in the creation process, right after the initial trimming before I built the mounting flange.

if you aren't great with fiberglass, i would buy a cheap moped fender on ebay and use that. It'll be much cheaper and lighter, and with more simple curvatures than most motorcycle rear fenders.

The front half of a generic UJM front fender works great too.

All good points. I love the idea of making one myself, and last night Bret from GFTP emailed me back about their Ducati singles mud guard fitting perfectly on a vertical 175 frame. I know their name is well known but would a fiberglass one hold up over a steel custom fender option? I just keep thinking it will crack but then again full fairings and everything are made of it.

Here's the link to the GFTP one:

it's hard to visualize how that ducati one looks on a bike, since the product photo is kind of nebulous. try it out and see. regardless of material, you can't really build one for less than that price, so go for it.

i wanted the type of fender that comes on modern super bikes, but styled like it belonged on a 60's bike.

As per fiberglass cracking…… it shouldn't. Not to say it WOULDN'T, but it shouldn't. This is a swing arm mounted fender, so it shouldn't EVER come in contact with the rear wheel. If it is going to crack, it's likely due to intense vibration. You can use rubber washers in your mounting process to prevent that.
