The easiest bike I have ever ridden is the 2002 Kawazaki ZX-12R I co own with my brother, though it is blody fast (302+ kmt) it's so wellbehaved and easy to putter around on.
Today my arms are not able to drive a bigbike more than 20km in one go and I have not driven the ZX-12 for the last 3 years (got a 50cc scooter to zip about on though). But I swear car drivers are much more dangerous now than 30 years ago, swerving without looking and signaling could happen in the old days and one always needed to be a bit on your toes especially behind older drivers with stiff necks. But now.... it's sometimes they are looking and or signaling, it's blody dangerous out there compared to how it was 30 years ago (This is in rural Norway). Not to mention drivers of big SUVs that seem to have problems keeping the car on their side of the road, it's bad to meet them in a car but on a left (right if you are in uk) blind turn on a big bike... you better not be carrying to much speed.
I think many of our cars have so bad outward visibility in the back and to much of a video game going on in the front that we are now driving less safely than 30 years ago. I belive I'm actually a safer driver when I turn off most of the videogame and just drive the car old school.
