Time to think about a dirty bike... The biggest I've been on (offroad) is an XR400 20 years ago, basically just putted around on that. Otherwise it's been either pitbikes, or again 20 years ago I did some pit riding on YZ60s, XR100s and XR80s.
In other words, all I know is small crap.
Would a modern 85cc mount be too small to enjoy?
Other end of the spectrum, can you SX/MX ride a Honda 250X 'woods' machine?
Edit: Ideally this is going to be a beater, dirt, ice, snow, possibly light dual sport duty...
