As long as it's over 16 years old it's fine

I think looptail is pre 85 but someone who actually knows what he is talking about (like Ash) will no doubt be along soon  :daumenhoch:

I thought that all rippers from 79-84 were all the same, and the serials on loopy rippers weren't consecutive, so it's impossible to determine a precise date. Here's an old thread that might help though http://www.radbmx.co.uk/forum/index.php/topic,157725.msg1567412.html#msg1567412

Keep it  :radbmxsmilie:

Cheers lads. I read that looptails were early but the rest relied on serials or cable guides on later models which I can't see  ???

where do you continuously find these gems. I used to scour the Internet and never fook all that some other bugger hadn't already and then highlighted it by posting it all over Facebook and forums. You are a treasure hunter supreme good sir.

For years it was thought you couldn't decipher Ripper serial numbers but with hindsight and a few hundred people knowing what year they bought their bike and it's serial number there's one or two people that can maybe nail it down to a year, maybe.

Brian Hays would be the man to talk to I expect.

Yes, there must be trends, even if they are not completely sequential/strictly date stamped. I think its a fairly safe bet to say that at the height of bmx, there wouldn't be many frames sat in warehouses and in shop stockrooms for long. If a bike was bought in August 1983, i'd say it's fairly likely it had only been in the country for 6 months max. Any thoughts?

if this frame has no serial number on the dropout the it is most likely to be pre Nov 1979, serials started then as the law in california changed and all bike had to have a serial as from 1st january 1980.  :daumenhoch:

as for dating a pre 85 ripper by its serial, there is a guide but it is only that as there have been many exceptions to the guide found and Scot himself said that a ripper cannot be dated by its serial as in the early years a whole batch of stamped dropouts were made and they all got mixed up one evening when every one had a few beers......how much truth there is to that no one knows but as i have said i know of several exceptions to the year/serial guide.

guide as follows

PK2 late 1979
PK3 1980
PK4 1981
PK5 1982
PK6 1983
PK7 1984

this guide also applies to Race Inc's with the PK replaced with either RM for the cro-mo frames or RA for the alloy frames.


hope this helps  :daumenhoch:

Interesting info about bikes having to have a serial number from 1980 onwards. I presume that was only California law, hence why the likes of Hutch frames continued to have no serial number (as they weren't made in California) until 83 ish

Plenty of good info already posted for you Clint about the serial numbers.
Now along with the serial numbers the other way to age a Loopy PK is the down tube decal, 79's had a single large square SE decal, 80's had a foil type decal that wrapped the seat mast and from then on it was your type of mast decal.

Also 79's are pre serial and have a thinner brake bridge than 80 onward.
Nice looking bike and worth a punt if the cash is right and maybe it will head over to me after that  :LolLolLolLol:

Ohh and I've now got your messages about the pedals, I'll send you a cage up if you still need one  :daumenhoch:

If the seat clamp area is damaged its  just more of an excuse to tack on a standing platform   :whistle:

I saw that one from Alan's, wasn't worth the money with all the damage and money needed to spend on it.

Didn't know how much it was up for, but someone bought it. I only found out about some of the clearance stuff last Friday evening. Went to have a look on Saturday. Not much left that was any good tbh. Bought a few magazines, (bi weekly, BMX Action bike) but that was all..

I never went in buy got sent a bunch of photos of some stuff.

The problem with a frame like that is it'll cost a minimum of £100 for repairs, plus £40 post, £100 new paint, £30 decals. So all in it'll be around £520 with the initial cost for a repaired frame that probably won't be heat treated.
You'll get a nice original finish for money not far off that.

'79 Ripper, no serial number as mentioned. Should have the birthday of the first person who bought it stamped on the bottom bracket though, mine's 11-22-66.

My question - Just bought a 2009ish bike (it's well ratty!) and can't find a serial number anywhere? This normal?

Ta for any info!
