Can anyone identify what these are off? #1
I have a pair of forks which came off my CT1 which I would like to identify. They are 30mm tubes and approx 30" long.
I also have a NOS exhaust which I would also like to identify, I think it might be for a HT1 but you guys are the experts.
Thanks, Pete.

Afternoon Pete.

Not a direct answer to your fork question, but attached is a link to a US manufacturer of replacement forks. They conveniently list the forks in sizes, so this might help you narrow down your search if no-one comes up trumps here. The 1975-1976 RD125 is also 30mm.

.

Not sure, but the forks look similar to earlier Suzuki forks . . . something like a TS125 or TS185 model
You're correct about the muffler . . . it's for a HT1

All I can say is wow at the knowledge base here, I own a 1972 TS185 and didn't even recognize the forks. :Ugh

Since I have a ratty pair sitting next to a parts bike, figured may as well confirm; 30mm tubes, 31" to the top of the nut on top. Not bad forks at all, in a way easier to rebuild than the Yamaha because the collar screws off to separate the tubes.

On second look your's don't have the threaded inserts for a fork brace/low fender like the TS125/185 models have.

I've been searching, could they be from a DT100 circa 1974?

That is what they look like to me, a 74-75 DT100. Need more measurements to confirm.

Close but no cigar. these are from my 1974 DT100 I have.





These do not look that much like the forks in the OP. The upper tubes look to be about 30 mm in diameter.

the ends of the forks where the axle runs through on these forks are shaped completely different than on a 1974 DT100A.
