Better suspension, handling and FI are all welcome in modern bikes as is ABS. Traction control is a selling point joke on cars and trucks, learn to control the throttle and identify road conditions for the love of god it's simple.

The 80s were a good time, as were the 90s before technology got so complicated it became stupid.
I have never been a want type of guy, my first bike was a honda trail 50 which as Molly stated was indestructible, and believe me country boys will try to destroy anything, it was a beast.
Next was a 72yami endure 360, that thing had crazy power but the suspension of a jack hammer, how people raced bikes with that nonsense suspension is insanity at it's finest. Next came the YZ 400, stupid power and the suspension made you feel like you were playing on a mattress.
My first street bike would be an 82 Yami Virago, I toured on that beast and rode it all winter long here in Montana, the coldest would be -15, that was stupid. wool inserts tucked into leather fencing gloves, a snowmobile suit and off I went! Proof as my boss says that The good lord watches over drunkards and fools.
I rode that bike for 13 years and sold it for 50 dollars less than I paid for it.

I could go n but my list is short, point is people think they need high dollar everything to have fun. IN reality all you need is some balls and a sense of adventure, ride what you got, life is too short not to.
