Back then it was way cheaper to trade them back in every year for sure. I got a new bike for like 25 straight years.Had that bike... cant believe that's what bike used to cost in the 1980's ... no wonder I got a new bike every year back in the day...lol...
You missed Knox's point. It's inflation rate.Keep in mind you are talking the price of a 125 2 stroke in 1983.
A 2022 YZ125 MSRP is $6899.
I also made $3 an hour in the mid 80's.
You can do the same thing looking at cost of cars/trucks, housing, etc.
