I may have access soon to a rather large 3d printer if there is files for the shroud I can probably print it and send it to somone who wants to make molds

Sounds like a good plan Matt. What sort of time and costs are you thinking in making a 3D print of a pair please?. I am happy to contribute if it helps.

If somone sends me the files it will probably take a few weeks. I think one shroud will probably take several days and then I can ship them to whomever wants to make molds. I don't have access to the printer yet but likely soon. It prints 500mm by 500mm by 500mm which I think is big enough. If not I can split it into two pieces and glue it together for a full shroud. My current printer is 300mm by 300mm by 400mm and it was close to fitting the bulk of the shroud when holding it up.

I unfortunately do not have any 3d files of the shrouds I designed. That is all BRP property. I simply only have a left and right 3d printed copy. If someone with a scanner is willing to come by and scan these, I’d be more than happy to tweak the files in cad to get them print ready again.
printing these seems like pretty short term solution though.. one tip over and theyre toast.

Once we have a master, I can create a mold and make resin copies. I will, eventually, be making molds for the mud flap and most of the original plastics. I eventually plan on making a replacement rear subframe mold to make fiberglass or carbon fiber frames, but that will take a while. We have the original shroud 3d model that could easily be modified for flat shrouds, however my 3d modelling software does not like the mesh.

@Blatant Moto could mail you the actual newer 2020 style shroud to scan?

I am working on a replacement set of shrouds at this time. The one hang-up I am having is if I move the shroud up to expose more of the frame (to keep the bodywork narrow and look like the CRF) the marks on the frame show where the stock shrouds rub. For some this might not be much of a issue if you do not have a bunch of wear but I am sure there is some bikes out there with a lot of use and wear.

Great effort - would love to see a mock up or something showing how you have it laid out.

Persinally I’d rather have the narrow layout and any cosmetic scuff marks from existing would be secondary or not even a concern IMO.

Cheers

Awesome news!.

Are you working from the CRF design or have you been using a 3D printed option?, like we above are trying to make work!.

Really would be good if you can post some pics and more info of your process please. As you have read its a hot topic and one that will have many to support your time and costs.

P.S. What bike have you got?.

I am using a combo of the OEM and a CRF combo scanned and printed. From there I am removing material and thinning where I can. I am leaving town for a week but will get back on this then. The rear view pick is before removing the lower section of the shroud. There is more to be gained at the lower portion. I am building up the print so I can thin it down.

looks awesome. Keep up the great work!

Is this based off the 2021 crf450r or the 2018-2020 design?

I love seeing progress on this project! (y)

I wouldn't worry about the old should scuff marks. They can be buffed out or covered up with friction tape.

I am all for extra-thin shrouds. But I would keep the bottom line of the shrouds parallel with the bottom line of the rear subframe, like on the stock shrouds. Else, an odd kink could create a flow discontinuity.

That is an awesome design - I’d say it’s good enough for production - only change that may be nice is reducing the length of the pointy tip at the front by the triple clamps, but not that critical.

Great work

Does that pointy part curl in at all? I wouldnt want the boot edge catching on it when turning. As a taller guy my boots with knee braces on can catch the edge of the shroud. Some bikes the leading edge is rolled in some to prevent that from happening.

great job over all!

The front edge will have an offset front edge like the stock Honda shroud. I have just been refining the print so I can do a final reprint of both shrouds to send off for the plastics mold. Just takes longer when working on it between other projects.
