That's as Old as a TS185 gets!
1971 Model,,,the 1st year it was introduced
Suzuki made a Huge number of those bikes(where they all went,,beats me),
But they were great bikes in their day,,,fast,reliable,good handling.
It was a Different world back then,,,,TS's weren't "motocross bikes",,,they were "Enduros".
What was was called "Trail Bike" just a few years before .
They were tons of fun in the woods,,anywhere off-road,,,and surprisingly good "street bikes".
All 175~200cc class bikes were extra cool becuase most were like Overpowered 125's.
They came to be considered "oddballs",,,an in-between size bike,,,,and people eventually came to "skip" directlty from 100~125's to 250's or larger.
That foolish stunt of consumer mkt demand lasted almost 2 generations,,,,look around today and in recent years almost all the mfgrs have gone Back "Big 125's/Little 250's" with their 150~180~200~225~230cc size bikes.
To me that confirms what a great niche the 175class bikes were all along.
And in it's day,,the TS185 was 'bout good as any of it's competition.
The Serial Number is actually written as
The -18079,,,,was an actual count of the bikes' sequence off the assembly line.
The very 1st one was TS185-10001
2nd one was -10002,,,and so on
Yours is #8,079th
The 1st year of production is known to be '71.
The Seriall Portion of the ID number began with 1xxxx.
So we KNOW that any 5 Digit Serial Number beginning with 1 ,,,Must be a 1st Year model,,,1971
The 2nd Year,,,began with a 2,
# 24292 actually
Suzuki runs their numbers until next Year Model begins.
Starting from the beginning,,,at 10001 in '71.
The LAST 1971 would have been #24291,
Then the Next bike was a "72,,# 24292
The '72 Numbers rose as bikes were produced,,
until the 1st '73 was #52592
1st '74 was # 84xxx
And so on and so on.
They had several changes in the serial number
'77 changed to TS1852-
and started back again from -10001
The "2" added to "TS185" is what distinguishes Pre/Post '77 models
And its how we know your TS185-1xxxx is a '71
and Not a TS1852-1xxxx '77
TS1852-ran till '81 when Suzuki adopted an OPTIONAL Version of the ISO'79~'80 VIN Number Standards,,,,
and everything was encoded in a "17 character" VIN number TYPE of format.
It was less than 17 numbers though
'81's began with VIN # JS1SG11A B xxxxxx
Their Engine numbers maintained the Old style "TS1852-"
Many of the parts among All TS125's and TS185's are interchangeable---but Not All.
The bikes went thru some updates/variations,,,,extensive enough to become an actual "New Model Type"
'71,'72,'73 are "all the same",,,Model Code 290
You can contact any Suzuki Dealer and they should be able to confirm that Yours is a 1971----1st Year of TS185's.
