A motorcycle including a frame to which an internal combustion engine is associated, from which internal combustion engine at least one exhaust pipe of combusted gases departs, the exhaust pipe having an open terminal, the frame mounted on a front wheel and a rear wheel, a control board or unit included, for controlling torque produced by the engine and other parameters such as velocity of the vehicle and spatial position thereof with respect to the road surface. The motorcycle including a system to verify when the front wheel of the motorcycle detaches from the road surface during acceleration. The system includes a choke for partializing the section of the exhaust gases outlet area from the exhaust pipe, during partialization. The partialization obtained as a function of the torque produced by the engine and the position of the front wheel with respect to the road surface.

A curb valve cradle for maintaining operable access to the operating nut of a curb valve with a valve key wrench tool. The cradle has a pair of spaced-apart upstanding arms connected together by a base. Each arm has multiple stop ridges arranged in a vertical series along opposite interfacing surfaces of the arms. A retaining ring with a central opening is matingly slidable between and along the upstanding arms. The retaining ring has a peripheral latch flange protruding radially outward and engageable with the stop ridges. The latch flange and stop ridges are configured to permit the ring to be slid downward between the upstanding arms from the top free ends of the arms and pass the stop ridges and to resist or prevent the ring from being slid upward past the stop ridges.

The present disclosure provides shortening prevention sleeves for adjustable underground utility boxes, underground utility boxes including such sleeves, and methods of preventing shortening of underground utility boxes with such sleeves. A sleeve comprises a substantially rigid elongate tube that defines an internal cavity. The tube is configured to allow a stem portion of an adjustable underground utility box to extend fully therethrough via the internal cavity. The sleeve also comprises an opening that extends along the length of the tube and provides a passageway into the internal cavity. The tube is configured to allow the stem portion of the box to pass through the opening and into the internal cavity. The sleeve is configured to extend over and along the stem portion and between enlarged top and bottom portions of the box to prevent the stem portion, and thereby the box as a whole, from shortening.

The disclosure teaches an adjustable/extendable piping system/module for associating fluid access products (such as fire hydrants) to a buried fluid source. The piping system defines an adjustable configuration that allows for the overall length of the piping system to be modified to compensate for different bury depths. The disclosure further teaches a flex module configured for associating a fluid product with a piping system connected to a fluid source. The flex module is configured to flex a predefined amount to prevent damage to the system from low energy impacts.

A pit defining an opening and having a footing. Cutouts are located in the footing and are created in mold to avoid secondary cutting operations. The wall of the pit above the footing is narrower than the footing and includes ribs extending from the wall for added compressive resistance. The ribs may vary in size both in length and extension into the center of the pit.
