One (me) wonders how you would notice you can shift gears without the clutch? Not something I would try myself on my YZ. Especially when I have it spooled up I'd much rather hit the clutch than click the shifter "just to see what happens" !!
I do know that a lot of manual trans cars/trucks can shift without the clutch though. Had an old 1980 Dodge I used to shift without the clutch regularly. Rule of thumb for me there was about 1000 rpm lower than when you pulled out of gear it would go into gear, but more of a feel thing. That I didn't care about breaking as much as my bike though!
