In my opinion...
I wouldn't put anything as small as a 250 on the interestate. Most references I got were to start with a 600.
I have only had one bike. Sold a couple months ago due to lack of riding.
1984 Yamaha FJ1100. Old, kinda heavy, but will MOVE if it needs to..
But I am 6'2" and 350 lbs.
I thought the class was worth it.
