Good post, but you cut a pretty wide swath with that statement. I had two pre-electronic aid era liter bikes, as you aptly put it--an '83 GS1100 and a '93 CBR1000F. Both were considered hot bikes in their day, but neither came remotely close to the S1KRR. Today, nearly all 600 class bikes will out perform either of them, I would think, just on engine power alone. The CBR was actually a gentle performer compared to our BMW, and I would not have a problem with a second-year rider riding it.if we were in the pre-electronic aid era, no dtc/abs i would say absolutely don't get a liter bike.
IMO, the biggest problem with the older liter bikes was not the lack of electronics or narrower tires. It was the weight! Both of my older liter bikes were in the 550 lb. class. Everything just works better on a lighter bike.
