I'll be more careful like the last 70 years of motorcycles that came without it.
A whole lot of people have locked up their wheels and ended up sporting toe tags over the last 70 years.
I've ridden for about 35 years and never needed them until a couple years ago. A school bus driver jammed on her brakes in the middle of an intersection and I was right behind her. My normal course of action is to swing out from behind such vehicles, so that anyone behind me doesn't flatten me, then apply the brakes.
Being more of a sport bike kinda guy, my first ever cruiser (a Yami Warrior) came with powerful front brakes. When I applied the massive binders sourced from an R1, they worked brilliantly, except that in sand that means they locked up brilliantly, and washed the front tire brilliantly, which sent the rear end of the lovely little twin right under the bus. Fortunately, I was dressed for the occasion and wasn't hut.
Had I got on the rear brakes, which are ever so much more effective on cruisers than sport bikes, I likely could have easily ridden out the bike fish tailing a little, but if I had had ABS it wouldn't have mattered what I grabbed in a panic, I would have stopped without the expensive drama.
That said, for a $4k delta, I'd have gone with the '11 too. If these events only occur at 33 year intervals, my next one should be my last.
