Military – TRW Military 500cc Side-Valve Twins YEARġ950 to Current engine and frame numbers match DATE Thanks to Dave Gaylin and Lindsay Brooke for printing the above information in their book “Triumph in America”. By 1950 frame and engine numbers were matching. TR5 models had separate number series engines from 101001 to 106424, frames from TC11001-T to TC13107-T. Note: All Grand Prix T-1 00’s have letter ‘R” suffix following engine and frame numbers. TR5 models did not have separate number series but ran concurrently with all other models. TR was followed by a ‘T” after the actual number. Frame prefixes were ‘TL” for the 3T up to 1948 and TC for 1949. This practice followed religiously and some single prefixes may appear on postwar models. Year shown in engine number prefix with two figures. “TF” for the T-I00 and later 39/40 Speed Twin. Frame prefixes were-“TH” for early Speed Twin. For example 8-T-33445 is a 1938 Speed Twin (later identified as “5T” instead of just “T”). If you search for 1234, you will only find bikes with serial numbers of 1234 and serials close to that - not a bike with serial number of 12345689.Year and model shown as prefix to engine number. We do not currently do partial serial searches.We do close serial matching - bikes with serial numbers that are close to the serial you entered are shown below the matching results under the heading "Serial Numbers Close to." - given a search of a serial number with a couple numbers/letters that are different or missing.Searching for either M4106I9CA1 or 200910427-2A will find the bike. If you see multiple numbers on a bicycle - such as in the photo of the Look bike above - try searching for just one of the numbers at a time. We split bike serials up by spaces and store each separately.We treat all these numbers the same way - a search for 005LLL will match a bike with the serial OOS111. Certain numbers and letters are difficult or impossible to distinguish between (e.g.We've done a few things to make it more likely that you'll find the bike you're looking for. When searching for a serial number, use our serial search bar - it's the second bar on our search form. Hopefully you can find the serial number on the bicycle you're looking at - email if you're having trouble.įinding bicycles by serial number on Bike Index is a critical part of our functionality. When adding a bike to the Index, it's best to enter all the groups of numbers and letters separated by spaces. On older Schwinns there are numbers stamped on both the drive side and non-drive side rear dropouts the one on the non-drive side dropout is the serial number. Some BMX bikes and a few Schwinn bicycles place the serial on the rear dropout. Some Schwinn bicycles also have the unique identifying number (their serial number) on the head tube.Ī serial number located on a rear dropout.

Rad Power bikes have their serial number on the head tube. The bottom bracket (where serial numbers are typically located) is circled.Ī serial number on the underside of a bottom bracket.Īnother serial number beneath the bottom bracket, aligned parallel to the frame. Here are some examples of where and what to look for: Most bicycles have their serial number engraved beneath their bottom bracket, but sometimes serial numbers are found in other places.
