I have a 2009 Kymco People 150 which I bought last fall, from a private owner . I really love the machine, but since I have short legs, I will have to cut the seat down. As with most 'sport' types, it has a sloping seat with bump in the front.
Question: If I actually have to remove that bump..why is it there? Is it to hold the rider on better, or is it just there to accommodate a helmet under the seat?
In other words, if I remove some or all that hard plastic hump from the seat base, will I find myself sliding forward as I ride?

Thanks....oldgunner
