The GS500 seems to be a good re-introduction bike. It’ll have slightly mroe power and response than the old 450, but it won’t feel like a completely different beast.
I know my area MSF-equivilant offers a “re-introduction” course. It is aimed at people who have either been out of the sport for many years, or learned to ride on their own and now want proper lessons.
I was going to say that if you remember all the controls and are cofortable playign around in a parkinglot, the ERC would be a good idea. Except that they don’t cover some of the really basic stuff (they just expect you to know how to do very low speed maneuvering). The reintroduction course might be the better bet since it spend moe time rebuilding the fundamentals upon which everything else is based.
Whatever you chose, Welcome back to the sport!
