Vintage Dirt Bike Q & A

Does anyone know if the tail light assembly of a 1974 XL250 is interchangeable with the 1974 MT250?

Yes it is, and apparently a few others too :

Ray,
You're the best! I was looking at paying way too much for a tail light on ebay and changed my search criteria to another one of the models you listed and found one in better shape for almost half the price.
Thanks again,
David

No problem! I'd never searched the entire MT250 taillight before, only the frame - so I was kind of surprised to see so many search results. With that many models using the same light, I wouldn't be surprised if NOS ones show up on eBay sometimes too (though I'd actually prefer an excellent used one for a bike I was planning on riding a lot).

I've got a tail light assembly with a lens.

The assembly frame is good shape painted over black but not bent or distorted, have the inner light assembly and red lens.

Interested? If so make me an offer not looking to get rich
