A new Batch of Honda CT90 and CT200 3D Printed Parts

 I'm continuing to find and endless number of opportunities to utilize my 3D printer to make useful parts for my also endless number of CT90 project bikes that I am working on, so I thought I would share a few of the latest CT90 parts that I have designed and printed.

All of the designs I share below, I first modeled using my ViaCad 2D/3D modeling program.

Speedo Light Bulb Socket Caps

On almost every older CT90 I work on (I guess they are all old...) the little rubber caps on that cover and help hold in the bulbs on the base of the speedo are cracked, disintegrating before my eyes or are just missing.

I modeled up both a short cap that has a hole for one wire and a taller cap that has a slot in its base that allows two wires to pass through as shown in the pictures below.



I have used these caps on speedo's from a K1 and a K3 and they should work on several other models.  I haven't checked them out yet on a speedo from a K0 or a CT200 but will do so soon.  Some later model CT90's and I assume CT110's have a bayonet mount that takes a larger diameter cap that I plan on modeling in the future.

I printed these caps using SainSmart TPU which is a nice flexible material, but significantly stiffer than the original rubber used for these parts. 

Here is the link to the .stl files at Thingiverse for both the short and tall caps.

CT90 Rear Fender Plugs

Another part that seems to be missing or in really poor shape on most bikes I pick up are the rubber plugs that go in the holes in the rear fender that support the addition of turn signals.

I modeled up both smaller round plug and the longer plug designed to three holes. I made the design of the features that fit into the holes slightly different than the original Honda plug designs as I printed these parts using SainSmart TPU which is significantly stiffer.

I have included links to .stl files below, but if you don't have a 3d printer I also sell a set of these plugs on eBay here at this link.

CT90 K1 Down Tube Support Bracket

It seems like a lot of the basket case CT90's I find are K1's which are kind of an odd duck in that many of the parts on this model CT90 are not common to any other models.

One part that can be hard to find if it is missing is the metal bracket that holds down the front end of the air filter housing and also provides the mount for the lower left side of the down tube cover.

I modeled up a working part and while its not as elegant as I would like the design, it is completely functional.



The bracket is designed with a small cavity at the end that you insert a standard 6mm nut into and that provides the threads for screw that is used to hold the lower end of the down tube cover.

I printed this part in PTEG which seems more than adequate for the application.  You'll also find an alternate design of this bracket that provides more clearance for the upper engine mount bolt.

CT90 K1 Speedo Housing Gasket

The other part I modeled for the CT90 K1 was the gasket that goes between the speedo and the headlight housing. You can find this gasket readily available on-line at the normal sources, but I had an itch and decided to model and print it up for one of the K1's I am currently rebuilding.


I also printed this part in SainSmart TPU.

CT200 Air Filter Housing Gasket

The last part I will share is a gasket that is used on a CT200 between the air filter housing and the frame.



This is one of the simplest parts I have modeled and I also printed this using SainSmart TPU.

  1. You are the man. Always love going through your blogs when I am curious or stumped about something. Bought your clutch tool a while back and it was very essential while I did my rebuild. Thank you for all you do and share.
