Abstract

A motorcycle having exhaust pipes of equal length and a V-type engine having a front and rear cylinder block. The exhaust pipe associated with the front cylinder block extending directly back to above the rear suspension mount. The exhaust pipe associated with the rear cylinder block extends downwardly to beneath and around the rear suspension mount and then upwardly to above the rear suspension mount. Both exhaust pipes terminate above the rear suspension mount to connect with mufflers which extend upwardly and rearwardly adjacent to the back stay structure. The exhaust muffler systems are fixed to the back stay structure adjacent the aft end thereof. Pillion step brackets are fixed at the intersections of the back stay structure with the center frame members to insure appropriate strength in both the mounting and remaining in the frame.
