Help Preserve the OEM Honda ST1300 / Pan European Front Speaker Enclosures
Hello everyone,I'm hoping the ST/Pan European community might be able to help with a project I've been working on for the last several weeks.
I'm attempting to recreate the discontinued OEM Honda front speaker enclosures (Accessory Kit 08A54-MCS-800) as accurate 3D-printable models.
This is strictly a preservation project.
I have no intention of selling these or making money from them. My goal is simply to recreate a discontinued Honda accessory so other ST1300/Pan European owners can keep these bikes original if they choose. Once the model is complete, I intend to upload the file free of charge to the ST community.
Why I'm asking for help
As many of you know, these speaker kits have been discontinued for years and are extremely difficult to find.The only potentially available options are excessively expensive to ship, or are not available to ship to met at all in the US.
Unfortunately I own a US-spec ST1300, where Honda never really marketed this accessory, so I don't have an original enclosure to measure.
Over the past few weeks I've searched just about every source I could think of:
- Honda accessory parts catalogs
- Bike-Parts Honda
- CMSNL
- Partzilla
- Honda EPC diagrams
- Google Images
- eBay listings
- European classified ads
- Pan European accessory brochures
- GL1800 speaker information (to compare the OEM speaker)
- Old forum posts and archived websites
- Front Speaker Kit: 08A54-MCS-800
- Right enclosure: 08A54-MCS-80001
- Left enclosure: 08A54-MCS-80002
- Speaker: 08A10-MBL-80001
Current progress
Using photographs, perspective correction, and CAD reconstruction, I've already recreated much of the front mounting geometry.The remaining challenge is confirming dimensions so the model is as accurate as possible.

I'm looking for anyone who has...
- An original speaker enclosure
- An original speaker kit
- A bike with the speakers removed
- Spare housings sitting on a shelf
Photos that would really help
If taking measurements isn't convenient, good photographs are still incredibly valuable.The most useful photos would be:
Front - Photo taken perfectly straight-on.
Rear - Straight-on showing mounting features.
Left side - Camera centered on the enclosure.
Right side - Camera centered on the enclosure.
Top
Bottom
45° corner views - These help reconstruct the curved surfaces.
If possible, place the enclosure on graph paper or next to a ruler.
I have attached photo samples located online, including my initial attempt to reverse engineer the enclosure dimensions.
Measurements that would help
Even a few of these would be enough to greatly improve the model.Front face
- Overall width
- Overall height
- Thickness of front flange
- Diameter of speaker opening
- Distance between mounting holes
- Mounting hole diameter
Enclosure
- Overall depth
- Wall thickness (if visible)
- Internal depth
- Speaker mounting surface depth
Mounting tabs
- Hole diameter
- Hole spacing
- Thickness
- Offset from enclosure
Speaker (if removed)
If anyone happens to have the original speaker removed, measurements of the following would also help:- Overall frame width
- Mounting hole spacing
- Basket diameter
- Overall depth
- Magnet diameter
Even simple tools are enough
You don't need anything fancy.A ruler, tape measure, or inexpensive digital calipers are more than adequate.
If you're unsure what to measure, simply post photos and I can mark them up with exactly what dimensions would be helpful.
Why I'm doing this
The ST1300 and Pan European have become modern classics, and unfortunately many of Honda's accessories have disappeared.I'd like to preserve one small piece of that history so owners still have the option to recreate these speaker enclosures rather than having the design disappear forever.
Once the model is complete and verified, I'll upload the file for free to the ST community.
I'm even willing to help compensate you for your time.
If anyone is willing to help with measurements or photos, I'd be incredibly grateful.
Thank you!
Alex
