Re: Old School Redline serial numbers (please post if you have one)

The serial number on my Pro-Line is 340790. It's a '79/'80 that I received for Christmas in 1980. Here it is as a young pup: tongue

My recently acquired '09 MX-24 is soon to capture the essence of that minty fresh Pro-Line since I can't bring myself to restore the old dog, erasing it's history. Off to the powder coater tomorrow with the MX-24. smile

Re: Old School Redline serial numbers (please post if you have one)

I see a lot of incorrect info being tossed around, here is what I have from my research over the years.

70’s US made Redline serial numbers and year comparisons.

I compiled these from researching Redline and Linn Kastan over a 10+ year period starting back around 03-04, also from comparing pictures, frame styles, serial numbers I found online and from numerous interviews I've read that Linn Kastan had done, as well as a few email to Linn himself.

These are not exact but the closest year breakdown of early Redline serial numbers available.

100 up to 260ish would be considered 1974
They only made a little over 150 frames in 74.


260ish up to around 800 would be 1975
There were 637 first gen Squarebacks built, plus the few Looptails built in late 74 which brings the serial numbers to around 740 plus the 37 Monoshocks built in 75 which is how I come up with the 800 range for the cut off between 75 and 76


800ish up to mid 5300 would be 1976 
The first 76 Squarebacks built had a larger top tube, I've seen one of these that has the serial number is in the mid 900’s. I know they went back to the smaller tubes on the frames in the 1000’s do to pics I have found. The 16” Squarebacks came in somewhere in the upper 2000’s.

The cut off between 76 and 77 is somewhat fuzzy, I’ve found Squarebacks with serial numbers in the 5300’s and I’ve found MX II’s with serial numbers in the 5300’s which is how I come up with the mid 5300 range. I know there are a few that say they made Squarebacks in the first few months of 77 but there is no evidence to support this.


Mid 5300 up to approximately 09500 would be 1977   
77 was a year full of changes for Redline, starting with the introduction of the MX II which was basically a Squareback with the back half changed. Then with the production of the Proline that started in March, the early Prolines also had no gusset below the head tube and they had a “PL” stamped after the serial number, I’m not sure how long they did this or on how many they made like this, but all early Prolines I've seen had it. They also moved from Northridge to Chatsworth in late 77 which brings a few more changes, one being the switch to the vertical head tube decal and at this time they added a “0” to the beginning of the serial numbers (084xx) which was done at the new factory so they would already be set it up for five digit serial numbers at the new factory being that they were so close to the 10000 mark. The MX II also went from having one bend in the seat stays to 2 bends for extra tire clearance. (somewhere around serial number 09000)



09500 up to approximately 21000 would be a 1978
By March of 78 they had built 10500 frames, (serial number 10600) the serial numbers at the end of 78 are also a little fuzzy, I originally though the switch was around 22000 but I have found no US serial numbers above 24000 and since they carried the 5 digit numbers into the first half of 79 I now believe it’s around the 21000 or even the 20000 range.


early 79 US made would be from around 21000 up to around 24000

late 79 US made started with 340xxx and went up to around 343xxx
1980 US made serial numbers started around 343xxx and went up from there. I cut most of my research off around this time period so I don't know much on them after this point.

Starting in mid 79 when they started having complete bikes built at the Kawamura factory in Japan  "ALL" Japan built frames were sold as completes. This was the whole reason they started building bikes in Japan, It was just cheaper to import a complete bike verses importing all the parts needed to build the bikes, it also kept them from having delays in production from back ordered parts since most of the parts were built in Japan anyway. Frame and fork production remained in the US and was sold an bare frame and forks only.



All Japan Redline serial numbers start with the letter "R" and a letter that follows which determines the year. This was something that the Kawamura factory done on all frames


RI = 79
RJ = 80
RA = 81
RB = 82
RC = 83
Etc. etc…


The MX III started off as a decal mistake at the Kawamura factory in 1980, they ended up going with it to save the cost of replacing the decals. Despite the myths, there was no difference between the MX II and the MX III in the first year, they were both complete bikes. The MX III became a separate model by 82 but this is where I cut my research off so I don’t know the exact details on it except they became separate models, the MXIII 700 and 600.


I'm looking for a clean 1975 Mongoose (long) frame, and a nice original finish Mongoose Two/Four

Re: Old School Redline serial numbers (please post if you have one)

Would be nice to gather a thread with the "knowns" on Redline frames.   The only data I have is my my Proline II that I bought in the summer of 1981.  I still have it and it is a RA serial number with brazed dropouts and a made in Japan sticker.   I bought it as just a frame/fork set and built up.   Here it is in the museum:  http://bmxmuseum.com/bikes/redline/20447

i have the same RA frame with the proline-II decals. i'm not sure if some dealers were pulling the Carrera PL-20 decals off to sell as proline-II's in the US after stripping the completes. the frame tube decal would be a 1 piece wrap around.
my original proline-II was purchased in 1982 here in Australia. it was a 1981 US built frame set with consecutive number serial with tig welded rear drops.

Re: Old School Redline serial numbers (please post if you have one)

I have a Proline that has no prefix before the serial number. It is a 497069 number on the bottom bracket. It also has the Redline in an oval. Why does mine not have a prefix like: RA, RC etc.

Re: Old School Redline serial numbers (please post if you have one)

I have two (supposedly last year Aussie) 300 series that makes them the 18th anniversary edition. With stickers down near the crank reading 1972-1990. Anyway the serial numbers read RLw0807458 and the second reads RLw909220878. My dilemma is that although I know that the bikes were purchased at the same time, same place. Some of the stickers have been removed from one of the bikes, and it also had to be sent back to the factory for a fix because of a cracked head tube. But I'm wondering why there are an extra two digits on the serial number itself. Any ideas? And is anyone out there opposed to my theory that these are both last year Aussie 300's? Any help would be huge. Thanks.

Re: Old School Redline serial numbers (please post if you have one)

I have what I believe is an old Redline that we just pulled out after being stored about 20 years ago.  The serial number on it is DS108070.  I have not been able to find information to tie the serial number to Redline, model, and year.  I can post pictures if that would help.

I brought my frameset home on February 14 1981. It came with Carrera stickers, but has a 4" head tube. The serial number is a 3694--. With redline stamp. Hope this added some value to the debate.

More data....   I bought this Redline in the summer of 1981 and I still own it today.  It is RA06894 with brazed drop outs, hotdog stamp on the BB, made in Japan sticker, Proline II decals, and was bought as just a frame set that I built up.   http://bmxmuseum.com/bikes/redline/20447

Re: Old School Redline serial numbers (please post if you have one)

I'm restoring my old BMX bike, I bought used in 1990.  I've always thought it was a circa 1986 Redline, but based on the serial number decoder here, I'm in doubt.  The serial number is on the rear drop out, and reads: MT5810270.  That does seem to match any of the codes I saw posted, coupled with the fact that it's on the rear fork rather than beneath the crankcase.  It certainly looks like a Redline.  Were there any other cheap knockoff brands in the late 1980s that mimicked the Redline look?  Any other info to share?  I don't care whether it's valuable or not...it's special to me :-)
