Title: 1956 BSA C12G - is lucas PRS-8 correct switch
Post by: VintageBike on October 02, 2008, 02:39:10 PM
Can anyone advise if the Lucas PRS-8 is the correct switch for a 1956 BSA C12G.

Thanks

Nigel

Yes, - according to the 1956 Lucas parts list for BSA ("PRS8 31443E") doesn't mention C12G, only C12 .

I know there was a 'C11G' and a C12, but was there a C12G?

I  can  confirm  that  there  was  not  a  C12G  and  the  C11G  was  a  250  cc  SV  in  a  Bantem  frame

Whoops.  I meant C11G.  Does the PRS-8 still apply?  Sorry for the confusion....

Cheers

The PRS8 switch is listed in the 1955 Lucas catalogue for the C11G, but there's no mention of the C11G in the 1956 Lucas catalogue.

They  may  have  not  been  made  in  56,

That's what I thought initially, but the BSA OC does list the C11G for 1956: http://www.bsaoc.demon.co.uk/html/BSANumbering1951to1960.html

Roy Bacon's 'BSA Buyer's Guide' book doesn't list a '56 C11G, so it's possible that the C11G model could have been discontinued sometime during the early '56 model year?

the c12 for 1956/57 had the c11g engine fitted, this may be some of the confusion

The C11, C11G and C12 engines were OHV, the C10/C10L was the side valve model.

40+ years ago my first bike was a C11G.  According to my fading memory it was OHV with a plunger rear end.  And the frame seemed to be a lot sturdier than a Bantam.
