摘要： Disclosed is an exhaust extension apparatus and method for converting a motorcycle exhaust system into a dual or quadruple exhaust system. The device is suited for motorcycles, off-road vehicles, or a vehicle with a reciprocating engine with multiple cylinders. Each exhaust extension unit comprises two metallic pipes shaped and welded together to form an exhaust extension unit having one exhaust intake and two equal-flow exhaust exits. Two exhaust extension units may be paired and connected to the exhaust pipes on each side of a motorcycle rider's seat, thereby providing a quadruple set of exhaust pipes and further, an increase in the performance of the engine.

摘要： A bicycle is provided having a unitary steering tube-crown member and a unitary crank arm-spindle member. A multistage aluminum 3D forging process is used to form the unitary members. This may allow the fabrication of components with substantially hollow interior areas to reduce weight, reduce part count while maintaining high strength and ductility. The multistage 3D forging process provided also allows the combination of multiple components into a single unitary part.

摘要： A handlebar formed from a metal hollow pipe and having a generally uniform peripheral wall thickness along its entire length, including a longitudinal center portion, first and second end portions having a smaller outer diameter than that of the longitudinal center portion, and first and second, tapered intermediate portions connecting the center portion to the first and second end portions, respectively. The first and second, tapered intermediate portions and/or the first and second end portions are bent symmetrically with respect to the longitudinal center portion. The handlebar is produced by bending a hollow straight metal pipe, placing the resulting bent pipe between molds and feeding a pressurized liquid into the bent pipe while axially compressing the bent pipe to cause the peripheral wall of the bent pipe to plastically expand into conformity with a mold cavity defined by the molds.

摘要： This invention relates to a method for molding a bicycle tube and the method comprises the following steps: first, providing a tube and then controlling thickness of the tube by a drawing and extruding process for forming a molding portion. Second, plasticize other portions of the tube into particular diameters and shapes by plasticizing processes. Third, hydroform the molding portion of the tube by a mold and a hydroforming device for forming particular three-dimensional shapes. By applying to the above-mentioned method, the tube could be molded into a three-dimensional, unique and delicate shape.

摘要： To adopt die casts product as parts of a vehicle body frame. A vehicle body frame is provide with an alumite treating, showing that brightness and appearance of pivot plates which are die cast products differ from those of non-die cast products, head pipes, longitudinal pipes and cross pipe. By carrying out a local coating treatment on the pivot plates, the pivot plates are provided with a color the same as that of the pipe, the longitudinal pipes and the cross pipe. By making die cast products portion of constituent parts, the fabrication cost of the vehicle body frame can be reduced.
