Sorry cant help u. Not sure how familiar u are with Harley, but neither of those vin numbers are Harley. They would be aftermarket.

Id say u have a custom motorcycle,, not a harley softail. This makes it difficult for getting the right parts, for your bike.

Good luck and Welcome to the forum

Welcome to the HDFORUM.

PS..only as a suggestion by me as a USER, make another new thread over in the newmember welcome area to say hello. Hope you continue to enjoy your ride here with us on the HDFORUM.


Enter your numbers here. Appears you have a custom built by Daytec

The number "1D9SS64D4SH251639" not a valid Harley VIN. If you could take a picture of the VIN on the neck for the frame, that would help

The number "DKM810271" would be a valid HD Engine Identification Number (EIN), but something is missing in the first four digits... a letter or a number is missing. If what you wrote is partially correct, that is not a Twin Cam "B" engine (softail). It is a Twin Cam "A" engine (touring) and it appears to be missing the year code.

DK = FLTC Shrine

M = Twin Cam 103"

Year code missing

810271 = last six of VIN the bike came installed in from the factory.

That's just a guess, based on what you posted.

If you could take a pic of the EIN on the primary side of the engine, it would help. It's located on the top of the left side case, between the cylinders. The first four digits are the critical ones for decoding the engine history..


Here's a pic of the VIN on the neck, followed by a pic of the engine number on the case.

Ran it through the NHTSA vin decoder, got the same results @Jackie Paper got.
Interesting bike!
I know nothing about Daytec Center, and really don't know why it's showing as a 2025 year.
