If you sit on your bike ddez and alternate between pushing your bars forwards then pulling backwards, surely you see some obvious travel? I can get close to a centimeter, perhaps 8m or so and it's clearly not coming largely from the handlebar as the top of the stem moves also (of course you have to keep your head as still as possible.)
Okay i did it your way and got about 4m. Perhaps its not so noticeable with the flat bars when riding. But it dont come close to my Speed D 7 i used to have,feels way more solid. Im surprised actually cause no way do i feel it when riding. So now maybe we have the answer it flexes.

I would test ride a S- type if you can though.
Just slightly off topic but speaking of Dahon. I saw my first Speed TR today up close and personal. Dang thats a nice bike and price is good too. Sheesh 24 gears. Too bad i got it in for Dahon.
