Not sure if this the right category for this question or not; but here goes. In the 1978 to 1981 series of SR500's (US), do the motor numbers and frame numbers usually match or is it a bit of a hit and miss system? The reason that I ask is because the motor numbers and frame numbers on my 1978 SR500 don't match. That really doesn't surprise me as I purchased this bike as a "rolling chassis" and several milk crates of parts. Plus the title lists the bike as a 1981, but it has the rear disk brake which would indicate that it's a 78 or early 79 model. The seller advertised it as a 1978 also.  ? The frame # is 2J2-003635 and the motor # is 2J2-001078. Thanks for any insight anyone can provide on this issue! Carry on!! wiguzziman |

Hello Mate,
I am no expert on these matters but my 78 SR also does not have matching numbers. It does however have a drum brake on rear, I think models varied in different markets. I purchased my bike in Johannesburg, American models could differ. Someone with more knowledge on forum will probably be able to offer more info. I seem to remember a link on old forum listing frame/engine numbers in detail but I can not find the dang thing.

Here's the link to a frame number checker, but of course, no mention of whether frame and motor ought to have matching numbers from the factory. My guess is not, just from the straw poll above, and Guzziman: your frame and engine numbers are both low numbers, which could be consistent with how it came from the factory, maybe? sr500forum.boards.net/thread/2910/link-sr-frame-identification-chartEdit: Those who've responded above regarding their own non-matching numbers, it would be interesting to hear how far apart your frame and engine numbers are from each other, compared the the spread of Guzziman's low thousands numbers, to see if there's any kind of pattern or consistency there. |

Hmmm...how about that, mine actually match! 1980 US model, 3H1-001936. As to the difference in model year shown on your title, it's common practice here that the title reflects the year the bike was sold, not manufactured. SRs were slow sellers here, and it wasn't uncommon to have bikes sit for quite a while before being sold.

Very interesting!! According to the Kedo chart my frame is a 1978, but still leaves the question about the frame and motor numbers being different. As to the issue of the bike being titled in the year it was sold not manufactured leaves some doubt also. My first Moto Guzzi was a 1976 model that I purchased new/leftover in January of 1977 and it's titled as a 1976 model. But then I also have a 1973 Moto Guzzi Eldorado that was built in October of 1972, but is titled as a 1973 model. I think this title date of sale issue may vary from state to state. I know some states on the east coast don't require a title if the bike is older than a certian age. Makes it fun to register them and get a title here in the upper mid-west (Wisconsin).
Guess I'll just leave my title as is (stating that the bike is a 1981 instesd for a 1978). No sense opening up a can of worms that I really don't need to. I don't plan on selling the SR500 any time soon, so I guess the title thing is kind of a moot point.
Thanks for all the replys and the link to the Kedo chart! Carry on!! wiguzziman

Heres mine..frame-002528 . engine-007240. What that means ? not a clue regarding 'was that how it left the factory'. No doubt if and when I sell it someone will pop the question 'is it matching numbers ?' |
