Although Kymco literature says that the 2009 GV 250 has linked brakes, I do not see or feel that it does.
1. Place the scooter on the centerstand, and apply appropriate weight to get the front wheel off the ground, and get a friend to rotate the wheel as you pull the brake lever. Does the wheel get hard to turn ?
2. If the front brake is linked to 2 brake levers, there should be 2 brake hoses going to the front caliper (I think). I only see 1 hose.
Scoot safely,
