M27 Frame Number

Featured Replies

Hi all,

I just picked a nice M27 but can't seem to find the frame number. I checked the usual places, headstock and above the footpeg.

Has anyone come across this before.?

The bike was apparently bought new in 1967 in Spain then shipped to Canada shortly there after by the same person. He then got injured and the. Bike sat in storage for the next 45 years.

Wow..lovely bike..my 27 has frame number on right side of steering head..would love to see more pics..

No one have any ideas? Or maybe heard of this before?

Nice looking bike,rare in Australia. The only thing I could suggest is that it was a replacement frame, for whatever reason, and therefore had no numbers. No ideas other than that. I know recently a friend purchased a new Aprilia road bike frame and it was not stamped also I know of a recent purchase of a Gas Gas frame that also wasn't stamped.

Cheers Greg

My M27 is stamped on the steering head too, but there was a third spot where some early Bul frames were stamped - I think it was under the seat somewhere.

Thanks for the replies. I'll pull the covers, tank and seat off and see what I can see.

I looked mine over today again...I have it stripped to the frame for a winter freshen up..but saw no other markings. Is it a particularly early or late version?

Number on engine and all other documents is:

2700139

I asked the prior owner and he assures me it is as it was in 1967 new.

Yes, with such a low number your bike was definitely manufactured in 1967.

It was common practice for Bultaco, not to stamp replacement frames with serial numbers.

Hello Markg,

              As you may see elsewhere on the forum, I have a 1968 model 10 No.1275 which doesn't have a number on the frame and as far as I can gather did not have a replacement frame. Although it does have a frame number on the logbook as it was registered for road use.

Strange, but it seems this crops up from time to time.

Hi Larry,

I remember your M10 post. I have a M10, #1085 that has a frame number on head stock and also have a M49 series 1 with frame number on frame above footpeg.

I pulled the seat and tank off but nothing jumping out as yet. The prior owner of this one says it's as it was new so guessing it didn't have one.

Thanks for everyone's comments.

I'll pull it out if it ever stops raining and post some more pictures.

Mark
