Looking for a hub motor to fit that elusive 165-170mm drop out (opening size) usually found on Razor Dirt Bikes (SX500, MX650)? Pair it with a FarDriver ND72450 or ND72680 along with your favorite tire (3.00 - 10 or similar) and experience the low maintenance, quiet performance of a hub motor! Hub includes a 190mm brake rotor. Specs in the photo section.
