A front suspension device includes an inner tube fixedly connected to the crown portion of the front fork and movably inserted in an outer tube. A valve member is received in the inner tube and connected to a sleeve which extends from the inner tube and an adjusting member is connected to the sleeve and the outer tube. An end cap is fixed to the first end of the inner tube and connected to a hollow tube which is mounted by a ring member engaged with an inner periphery of the inner tube. A spring is mounted to the hollow tube. A core is movably received in the hollow tube and has a first end connected to an adjusting switch. A head is connected to the second end of the core and movably seals paths defined through the ring member. The spring is not compressed when the paths are sealed by the head. When a large pressure is applied to the head, the ring member is moved upward to compress the spring to re-activate the suspension device.
