rear seat pad comes off using the key on the nearside rear panel at the bottom of the “R” in 125R.
After that there is a 5mm? hex key running from the back towards eth front into the riders seat pad which you have to unscrew to get the seat off. after taht it’s a doddle.
Hey I found it!
theres a hole next to the 125… which unfortunately has no lock in it… instead… underneath there is an old cable tie someone has used to create a locking mechanism. give it a tug and the seat pops off!
