I think it may be related to the design of the transmission in motorcycles vs automobiles , sequential in motorcycles vs cars with the H type shift pattern, I have shifted gears in standard cars with no clutch but I had to rev match going into the next gear, and I have done no clutch up and down shifts on dirt bikes with no grinding or other noises, although the shifter effort was higher

on my cobalt SS when I no lift shifted into second it would usually grind sometimes it would just grind and not go into gear at all , I figure the synchronizer for second was weak , thats one of the reasons I started getting automatics ,there's less to worry about transmission wise , both self induced and defects
