I'm an even 6 feet tall, my Vader is the Gen 2 that has a slightly lower seat height than the Gen 1 -

I "fit" on the bike just fine ,but I will say that when i changed the bars out , i did stick some 1" risers under there ,and later i switched to a Grom Gen 1 seat which is a lot "flatter" which allowed me to slide back more than the "locked in " hump style Vader seat did.These 2 things taken together gave me plenty of room to be comfy whether
cruising or stunting ,at 5 foot 9 you probably wouldn't need to do any of it but swapping the bars is worth looking at solely because the stock bars really have a "blah" bend and look ,you can find some Renthal ctyle bars on Ebay that are $30 instead of the 70$ real Renthals are that will work just find, in your choice of anodized colors.
