I have a 300i downtown , I have to take the muffler off remove the left shock to clear the tire removal, behind the muffler take off the part (bracket ) mine has 4 bolts , then remove the axel bolt, and your wheel should come off, get something to lift the ass end of scooter, so the wheel will drop down, I have a hoist in the garage, you may have to use a tree branch, I have used that before, for the front axel there should be a bolt in the back of the axil bolt that locks it in, pick up the scooter by the handel bars and the wheel comes off easy, dont have to touch the brake pads , just check for wear, on reasembly use lock tight blue on all the bolts
