ehh go for what ya like. I started on a 650cc too. I got it in march. I think starting on your savage there, you could progress to any bike you want. use your head and you'll be just fine. After about 5,000 miles on my sv650, I then rode a R6, cbr600rr, and a gsxr1000. I felt confident enough to ride any of those bikes again. I haven't tested out the cruisers yet, mostly because the cruiser guys I know don't like the sport bike feel and won't switch up with me haha.
Nice looking savage btw
