TW201731719A - Motorbike frame for sufficiently utilizing the space located between the downside of the first reinforcing pipe and the main side pipe of each of the side pipe units - Google Patents

Abstract

The invention discloses a motorbike frame, which comprises a main pipe unit, two side pipe units and a reinforcing unit. Each of the side pipe units includes a main side pipe connected to the main pipe unit and an auxiliary side pipe connected to and arranged on the main side pipe. The reinforcing unit includes a center reinforcing pipe connected to the main pipe unit and a first reinforcing pipe connected to the center reinforcing pipe. The center reinforcing pipe is provided with a first connecting end connected with the main pipe unit and a second connecting end connected with the first reinforcing pipe. Due to that the height of the second connecting end of the center reinforcing pipe relative to the ground is designed to be larger than the height of the auxiliary side pipe relative to the ground, the space located between the downside of the first reinforcing pipe and the main side pipe of each of the side pipe units can be sufficiently utilized, so as to improve the space utilization.
