Development Aim
The “TZR250” was developed with the aim of bringing the feeling and riding characteristics of the fabled YZR factory machines to a production model. The Aluminum Deltabox frame was an important design point in realizing this goal.

Structure and Function 
The frame adopts a box-shaped cross-section that enables a larger cross-section surface area, lighter weight and high rigidity. Of particular note in the design is the structure by which the steering head and the pivot point are connected in as straight a line as possible and the fact that a special construction technique is used to give a triangular shape (delta) to the side surface to achieve outstanding rigidity. Another exterior characteristic is the added width that is given to the steering head area where particular stress comes to bear during riding.

Effect 
1) Thanks to the weight reduction (a dry weight of 126kg was made possible on the TZR250) outstanding handling was achieved.
2) The lightweight, high-rigidity chassis helped achieve high-level performance in the basis functions of “running, turning and stopping”.
3) Outstanding steering stability and nimble handling were also achieved.
