Try and run start a DRZ, you'll be huffing and puffing in no time bru, ask me, I've tried it only to find out the fuse at the battery was fried!! 
Heh heh, yeah, a kickstart is a bonus.. Although, having said that, the huffing and puffing would have been there if it had a kickstart anyway, especially with the problem with the fuse.. There is however a trick to run starting any non kickstart bike, though the bigger the machine, the bigger the physical challenge.. The big DS bikes, need a second person as you can't do both push and start..
My DRZ has a filthy habit of running it's battery dead after a few days in the garage. Has a power drain somewhere, batt is new. I have to disconnect it to keep it charged if I am not going to use it for longer than three days. When it catches me, it takes a few seconds and it's running.. Though because the charging system doesn't quite get the battery up quickly, properly, I prefer to give it an hour charge before I use it..
