Honestly, You should at least go with a 300 to 500.
You won't regret it. Because if you buy a smaller CC, at some point you'll wish you had bigger.
If you dont want to spend a lot of money, look for a decent used one. There out there.
I have a '97 Honda 300. It suits me fine and does what I need it to do. But there are times I wish I had a little more speed or power. Luckily my Dad has a Can-Am 650. So I'm covered.
Good Luck in your search
