I have one in my garage, it's an '82 that I bought new and totes "ALMOST" 5000 miles on it.
It's my baby, however I spend more time focused on work and family than on riding.
Got her fired up last month and so far put 5 miles on her this year. I eked 45 miles out of her last summer though...
I used to ride mine all the time, winter or summer, but of course I live in Northern CA and only have to contend with snow when I venture above about 1200 feet in the winter. I loved riding those dirt bikes. That one looks in great shape.
