Rear wheel alignment check
Improper alignment of the rear wheel results in excessive wear on the sprocket teeth, drive chain, wheel bearings, cush-drive, axle and tire.
Bent/twisted swingarm check
Just like a misaligned rear wheel, a bent/twisted swingarm results in a poorly handling motorcycle, uneven tire and drive-train (chain and rear sprocket) wear but in a more serious and dangerous way. For safety reasons, motorcycles with a bent/twisted swingarm shouldn’t be used until the problem has been rectified. If the bike hasn’t been dropped, check the swingarm bearings first.
