Fender extensions look "wrong" on all scooters. The only way to remove the ugly ducktail on my Zuma 125 is to cut it off. The turn signals attach to the top part of it, and the thing is also used as a support to hold other parts of the body together.
When temps get down to below 32 degreesF, the only thing that works for me is leather, plus heated gloves, because I got frostbite in my hands 25 years ago from riding in a snowstorm without any gloves (long stupid story)
What year is your scooter? The only ones I can find are 2009 models. Since reading so many positive things about it, I have about decided on one as my "freeway legal" scoot.
