The TS 185 was produced from 1971-2005
Suzuki TS series at Wikipedia says,
"The TS series were the first Suzuki trail bikes sold on the mass market. They were robust, reliable and performed well.
Possibly the pick of the models was the TS185 which is actually lighter than the 125 by a few lbs(3kg) and nearly the power of the 250 but with a much more free revving motor."

"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".
