its the specific market they are targeting. Im pretty sure most of it is the ecm tune and the ridiculous intake runner.
I get where you're coming from, coming from the grom world myself as well. However, Ive stuffed a TB cam in the trail, done the eife and decatted mine. it def has more grunt but i have to keep the mods 'in check' as i have a 2 stroke swapped OG grom and don't want to go down that path with this one as its my 'practical run around' and as tempted as i am to stuff a 40hp motor in it, i must. resist. the. urge. the lack of a supported ecm is , for me, actually good at keeping the temptaion to a minimum. however an anime 190 would be pretty sweet in the trail.
