Bultaco 198 Model numbers - help?

[smelling123]

Hi, i have what I think is a 198, the frame number starts with 198 and then some numbers.

The bike has the alloy bashplate/no frame rails at the bottom. Am I right in thinking the bashplate model was 198A and 198B?

If so maybe mine has been converted - if it has then its a professional job and looks very much like others I have seen so Im not worried but it'd be nice to know.

I'd have expected the frame number on a 198A or 198B to start with 198A (or 198B) not just 198...

Any ideas?

thanks

The frame number should start with two letters then a hyphen then comes 3 digits with the model number. like your mentioned 198 after that the serial number of that number, a or b models are marked by a second hyphen then comes the letter.

Number as follows:

AA-MMMXXXX-S

A: letters

M: model number

X: serial number

S: A or B model, (if none of this forget the hyphen and the S)

Here as an example for the serial nuber of an 199b model:

Frame less bottom tubes and with alloy bash plate factory-fitted from serial #19801770.

(according to the appropriate parts book, and unless someone out there knows differently, of course)
