Wheels and Tires
The SG250 uses a 2.50x17 aluminum-rimmed wire wheel on the front of the motorcycle, and a 3.00x17
aluminum-rimmed wire wheel on the rear of the motorcycle. Both the front and rear wheels use inner
tubes.
The front tire should be inflated to 40 psi cold, and the rear tire should be inflated to 36 psi cold. You
can adjust the tire pressure up or down slightly to provide the handling characteristics you wish.
Warning! Under-inflation or over-inflation of either tire will adversely affect the motorcycle’s handling
characteristics.
Both the front and rear wheel and tire should be dynamically balanced any time either tire is removed
and reinstalled or when a new tire is installed.
