Why shift? The CBR will do 90 in first gear. You shouldn't need to go faster than that when commuting.
I did/do it all the time on my CBR, R1, R6. But I dont know about K5's I think they blow up if you do it. (Bias answer)

Auto gearbox and moto gearbox are way different. Your truck or car is a syncro transmission and requires the clutch for gear changes. Moto gearbox is constant mesh, which is why we can shift without the clutch.

Had a couple buddies who never used their clutch and things were fine, and some others that have bent their clutch fork and really jacked up their transmission. I generally only do it when I'm going hard on the bike (ie: racing, drag racing) but that's it.
