February 13, 20215 yr Is there a way to identify what model/ cc a Bilty is from the frame number or engine number...? Help appreciated Regards Gary
February 13, 20215 yr Yes, on earlier models the first two and later models the first three engine and frame numbers identify the respective model https://cemoto.tripod.com/bultaco.htm
February 13, 20215 yr Author Thanks Woody.... Therefore frame number M-49 is.....Sherpa T250 1968>1971 Thanks for the heads up regards Gary

Therefore frame number M-49 is.....Sherpa T250 1968>1971 Thanks for the heads up regards Gary There were quite a few design changes made during the model 49 production. Frame design, rear hub design, brake pedal design, seat/sidecover design and engine outer casing design all changed between the first and the last
February 18, 20215 yr Author Following on.... just purchased a 198 with matching numbers... However going further the frame has RR prefix and the engine has RM prefix what do these refer too? It is also road reg and I assume wrongly the RR is “Road Registered” But I guess that is totally b/s help appreciated as always Regards Gary
February 18, 20215 yr Gary - Frame # will be RB R = 250 B = "Bastidor" (frame) Engine # will be RM M = "Motor" Check frame again. HTH
February 18, 20215 yr Author Lorenzo, thank you I have checked again it is RB ..! So R = 250 & M= motor Therefore 250cc engine Fantastic... Many thanks Gary

I posted earlier :- "R" prefix actually denotes 238cc. capacity of model 198, a late version still identified as Sherpa "T250" (Earlier 250's that were actually 247cc had a "P" prefix). Hope this doesn't confuse the issue too much...... Edited February 18, 20215 yr by lorenzo
August 6, 20251 yr I have a Bultaco with frame # JB-19907895-A . only info I have. Any inffo on what the numbers mean would be appreciated

Any inffo on what the numbers mean would be appreciated That means the frame is from a Bultaco model 199A. The 7895 in the number means that is the 7895th one made. The 199A is a Sherpa T 350 nominal capacity 326cc and made around 1979. Blue frame and blue plastics. The model before it is a 199. The model after it is a 199B.
