Abstract

PURPOSE: To prevent a back stay from interfering with exhaust pipes by providing a cross member for connecting main frames at a position separated from the lower face of a seat, projecting the back stay upward at the center of the cross member and arranging the exhaust pipes on both sides of the back stay. CONSTITUTION: A cross member 9 for connecting main frames 5b and 5b is provided at a position separated from the lower face of a seat 6. A back stay 8 is projected upward at the center of this cross member 9. The back stay 8 is made to branch out into a Y shape by a long pipe 8a bent to the left at an upper section and a short pipe 8b welded to the long pipe 8a and bent to the right for supporting seat rails 7 and 7. Therefore, space is formed on both sides of the back stay 8, and exhaust pipes 17a and 17a of a two-cylinder engine are arranged in this space. In this constitution, the exhaust pipes 17a can be freely designed without the interference of the back stay 8, and curved sections can be restrained.
