I think there is a problem with the structure! How? Here is what tight handling means:
Tight handling-- (a.k.a. push, understeer) occurs during cornering when the car's front tires lose traction before the rear tires. When this happens, the car will not turn as much as intended by the driver's steering input, and will start to drift to the outside of edge the turn -reference
Obviously, when a vehicle is not under driver/rider's control, it's a disadvantage. So, if the tight handling is decreased, it means it's an advantage, but the source says that the point is under the subtitle of disadvantages.
Thus, here is how the bullet point I think should be -
Tight handling while traveling at slow speeds, and steering response time is decreased.
