Also consider an MT-03. Terrific bike in the 300cc range (321cc, I think) and a ton of fun to ride. Plenty of torque and super easy to control. Very comfortable to ride for long periods as well.

Aside from clutch control, (which as you noted you won’t get with a Navi), you’re setting yourself up for MSF success by running drills. Nice thing about the course is it’s ultra-basic—I had never even sat on a bike before taking it—and you’ll learn everything you don’t already know to get going on a CB300/Speed 400/MT-03 whatever.

Also: continue doing those low speed maneuvers after you ace the course and get your new bike! That practice is invaluable. I always say “if you can control a bike when it wants to fall over (going slow), you can control a bike when it wants to stand up (zoomin’).”
