It seems the Rebel 300 and 500 use the same suspension setup so I have found some details on the suspension. Everything will be posted below
Front Suspension : 41 mm telescopic fork; 121 mm (4.77 in.) travel
Rear Suspension : Dual shocks with five-position spring preload adjustment; 96 mm (3.77 in.) travel (Showa with pro-link system)

The 41mm forks are set wide at 230mm apart for handling rigidity, comfort and style, and the lower legs are blacked-out. Trail is set at 110mm with 28° rake; the forks are offset at 30° and the result, combined with the 58.7 inch wheelbase, is a low 27.2 inch seat height and mid-mounted footpegs, for balanced and neutral steering.
