PROBLEM TO BE SOLVED: To provide a vehicle body frame structure of a saddle-riding type vehicle which can fully secure an intake opening area at a head part while inhibiting decrease of rigidity of the head part.SOLUTION: A vehicle body frame comprises: a head part 11 which supports a steering shaft 5 rotatably; a pair of right and left main frames 12L, 12R which extends toward back of a vehicle body from the head part 11; and an intake duct 21 which leads air which passes between the pair of right and left main frames 12L, 12R to an air cleaner 19. The intake duct 21 is made of carbon fiber reinforced resin. The intake duct 21 is provided to the head part 11 integrally at a state that the head part 11 is penetrated in the back and forth direction of the vehicle body.SELECTED DRAWING: Figure 4
【課題】ヘッド部の剛性低下を抑制しつつ、ヘッド部での吸気開口面積を充分に確保することができる鞍乗り型車両の車体フレーム構造を提供する。【解決手段】車体フレームは、ステアリングシャフト5を回動自在に支持するヘッド部11と、ヘッド部11から車体後方に延出する左右一対のメインフレーム12L,12Rと、一対のメインフレーム12L,12Rを通過する空気をエアクリーナ19に導く吸気ダクト21と、を備えている。吸気ダクト(21)は炭素繊維強化樹脂から成る。吸気ダクト21は、ヘッド部11を車体前後方向に貫通した状態で当該ヘッド部11に一体に設けられる。【選択図】図4
