How short is everyone requiring a low seat? Just out of curiosity. Is everyone trying to flat foot?
I'm 5'7", but with short legs even for my height (29" inseam).
I have the low seat installed in the lower position which lowers the seat height to 820mm (32.0"), and still cannot flat foot on both sides. If I keep my right foot on the peg, I can flat foot on the left with my knee pretty much straight out.
My suspension sag is probably around 70mm, which would bring the seat height to 750mm (29.5") with me seated on the bike. Given that my riding boots give me a ~1" lift, I should be able to almost flat foot on both sides but the low seat is pretty wide where it meets the tank which contributes to my inability to do so.
Why is it important to be able to flat foot on both sides? Well, because if you are determined to take your A/T on enduro trails as I do, it makes a huge difference.
I rode MX for close to 40 years and I am a pretty advanced rider in all kinds of off road situations. However, there is a significant difference between riding a ~220lb MX bike, up and down near-vertical cliffs, and trying to manhandle a 540lb (mine is a DCT) beast even on moderate trails.
You get the bike's center of gravity leaned over a little too much & it's game over. You will end up laying the bike down on one side and good luck getting it back on 2 wheels if there is nobody around willing to help.
I've laid my A/T down, twice, on the left side and both incidents happened when I came to a full stop and tried to get my left foot down. My foot placement was slightly off and I tried with all my, 5'7", 175lb, used to be athletic, might to hold up the bike and failed.
First time, I had my left leg trapped under the bike and my back up against a bolder making it very difficult to get out. Two big guys came to my rescue and picked up the bike with some difficulty. One of them said, "darn, how much does this thing weigh?"
The second time, I wasn't caught under the bike when I had to lay it down. I had stopped to ask a ranger for directions when it happened. It was I and the ranger picking up the bike and it wasn't easy to say the least.
Forget about those Youtube videos showing how to pick up a heavy cruiser laid down in a paved parking lot. It doesn't work that way when you are on a slippery off road trail.
Bottomline, flat footing an A/T is important when trail riding and regardless, cross your fingers and hope that there will be people around who are willing & able to help If you end up dropping it.
