I've got a frame number, can anyone give me any idea of what year I'm looking at, please?
*USA*SWM*RS175GS*D*OO46*

Thanks Noel,
It looks very much like the top one, but with leading axle forks.I'm being told it was bought in 1977. ???
-
Tony I got that wrong. This is the 77-78 RS GS. I think the one above maybe a 79.

Interesting stuff. I was just looking through the '77/'78 RS GS parts book and it lists both leading axle and straight forks. I also found a photo of a '77 RS250GS in Italy with the bendy swingarm like mine.
So maybe it is possible that mine is that year like the owner claimed. ???
-
My 2 bobs worth - straight steel swingarm puts it as a RSGS, not TF1.
-
if it has leading axle forks maybe part mx in there some where

Thanks for all the input, gentlemen.
I've been trying to nail this down once and for all over the past couple of days and he's what I've come up with.
I have a 1977 RS175GS with 250 top end (subsequently sleeved to 280). ::) It has a steel tank. The swingarm has been modified and lengthened, hence my confusion into thinking it was a later model.
SWM did offer leading axle forks as an option for the enduro models (they're listed in the parts book) but I've never seen another one with them other than mine.
I can relax now I finally know what I've got. :D
It's certainly a looooong way from being a nice original bike, but I didn't pay a lot for it and hopefully I can turn it into something fun to ride. :-\
-
sorry they didnt... only mx had leading axle... as for the 250 -175 you have a short stroke engine with a 74mm boar not the real 280 which was a long stroke are you from usa as your frame prefix states? oh i was one of the weird swm riders in the era sold them 7 years

Beauty, you can answer the millions of questions I've got then. :D
It's weird about the forks as the bike came out of the crate with them. Confirmed by owner and dealer. (I bought it off the original owner) And also weird that the parts book shows them as well on a '77 RS GS.

Were you a dealer here in Australia or in Europe or U.S?
I only ask as I wonder if it was a Euro thing. I was told that this bike was delivered to the U.S. in 1976, but is a actually 1977 model. It sat in it's crate in the back of Barry Higgins' shop in Georgia until the guy I bought it from, bought it off him in the early 80's.
But the other weird thing is that I can't find an engine number. Where is it supposed to be?
Thanks in advance for all the help you're going to give me. ;) :D :D ;
P.S. Whay sort of tranmission oil should I use.
It has gear oil in it now. 80W?
-
ask rotax were the engine number is
http://www.rotax.com/en/
-
so i correct my statement Australian prefix swm were shipped here with inline forks until i think tf3 81 when a nsw distributor took over from Bert Flood.....Gear box oil we always used ATF ie to lighten the clutch operation never a problem
-
ps i forgot eng number ??mine were top of the engine cases in front s/a pivot R/h side BUT i have seen it underneath stamped by hand
-
Yeah, I'm in Australia but the bike was U.S. delivered.
Thanks a lot for the info, Mr. Supermoto. ;D
-
Tony. I use Motul Transoil in my Rotax's without drama. Takes about 1.2l. Fill to the oil level hole (remove the cap head usually hiding behind the gearlever on the clutch case). When you go to drain the oil make sure that you remove the oil drain - a 8mm allen key removes it. Do Not remove the 17mm bolt or any other bolt under the cases otherwise we'll be going through the procedure on how to reset the kickstart return spring!
-
Leading axle Marzocchi forks were available as aftermarket forks at the time also.
-
Sick of me yet.....? ::)
I just checked the bore and stroke of my engine. It's a 76mm bore with a 61mm stroke which does make it a true 280.
That means that the bottom end isn't 175 like I was told. It's either a 250GSL or 280 TF1.
Maybe Japanese bikes aren't so bad after all............ :-\

Tony,
FWIW my understanding is that the 77-78 RSGS model had straight swingarm & shocks laid down at about 45degrees as per pic in NSR's reply #3 above. The 250 also had the short stroke (57.5mm) engine.
The model w more upright shocks, banana swingarm & rearset # plates (as per top pic in NSR reply #1 above) is 80 TF1 (tho they may have been available in 79).
My 250 frame # was *AUS*SWM*RS250GS*E*0007 & I was lead to believe it was a 78 model, which was almost exactly the same as 77 model. (Its now being raced in pre78 VMX.) My Eng # was 87577 & it was short stroke
The long stroke 250 engine (61mm) was first used in 78 on Canam MX4s as far as I know. So it seems to me your engine is a later model transplant (which is perhaps why you can't find an engine #). I believe they are not pre78 legal.
Whilst your frame is obviously RS175GS, it appears to have a later TF1 swingarm
-
Sounds like this bike is a bit of everything.
-
i reckon we will find out what happened to Amelia Erhard & Kingsford Smith before Tony finds out what SWM he has :D
-
Tony
Have you checked out the swm-moto.org site? Look under models. The TF1s were still called RSGS models
Looks like you have a 79 RS175GS TF1 frame (even if the frame # doesn't include TF1) w a 280 engine (available in 79). Note that the top shock mount location & rear subframe on the TF1 is quite diff to the earlier RSGS
-
Thanks JC,
I think you're getting close, but I've got no way of proving it.
No matter, it's still a fun bike and a little biy different. ;D
