I can relate, just turned 77 .....I can still take the curves, but I get tired easily,,about a 2 or 3 hour ride with breaks every 50 miles or so and Im ready for bed , lolI’ve always loved the sportster. I bought a new 2020 Iron 1200NS 2 yrs ago. I’m 66 now, and it will be my last motorcycle. It’s a great machine.
