Good choice on the ST. I hope it serves you well, and you will go in style.
I have 5 bikes now, most ever. Covid projects picked up cheap except what I had before, '13 Ducati Multistrada 1200S which is amazing.
Added an '82 Suzuki GS1100E w/Mr. Turbo kit, a '94 Yamaha XT350, and a '66 Norton N15CS (basket case, engine next to Ducati wheel).
In front is my '73 Honda CB750 frame, just waiting on a couple little things to finish top end rebuild and reassemble.
I realized that in my lifetime I've owned bikes from 50's through the '10's, and have 5 different decades in the garage.
