A snowmobile has a steering system with a handlebar, the system having a steering post comprising an upwardly extending yoke attached to the handlebar, a tubular post portion unitary with the yoke, the tubular post portion attachable to the snowmobile frame, and a lower steering arm at the lower end of and unitary with the tubular post portion, the lower steering arm projecting at an angle downwardly, forwardly and to the right. The steering post is unitarily formed by forging, casting, metal injection molding or the like. A central bore extending through the steering post formed by machining, the pair of bearing surfaces on the steering post formed by machining, two upper yoke arms machined to receive a handlebar clamp and the handlebar. The steering system may include a pair of spacer members receivable by the yoke, the spacer members then receiving the handle bar for providing handlebar height adjustment.
A steering system for a snowmobile having a snowmobile frame, the steering system comprising:
A steering post system for a snowmobile, the steering post system comprising a steering post formed of metal and having an upper yoke portion with two separated yoke arms, each yoke arm having a central recess sized for a handlebar, the two recesses having a recess axis, each yoke arm having a plurality of screw holes positioned on each of the two sides of the recess, the steering post further comprising a tubular portion with an tubular portion axis extending from the upper yoke portion downwardly, the tubular portion having an upper bearing portion with a bearing surface thereon for rotatably connecting to the snowmobile frame, a flange portion positioned below the upper bearing portion, the tubular portion extending below the flange portion to an elongate steering arm with a steering arm axis that extends outward at an obtuse angle to the tubular portion axis, the steering arm having an arm end portion with a hole for connection with a steering connecting rod, the steering post system further comprising a pair of spacer members, one each for each of the yoke arms, the spacer members each having a yoke arm interface side with a projection sized to the handlebar whereby said projections are receivable by respective central recesses of the pair of yoke arms, each spacer member further having a handlebar side with a recess sized for a handlebar, each spacer member having a plurality of screw holes that align with respective holes of each yoke arm, the steering post system further comprising at least one yoke cap, each yoke cap having a lower side with a recess for receiving a handlebar,
A method of manufacturing a steering system for a snowmobile, the method comprising:
A method of elevating a handlebar position on a snowmobile having a steering post with a pair of handlebar receiving portions, each handlebar receiving portion having a recess conformingly sized to the handlebar and a pair of flat upward facing surfaces on opposing sides of each recess, each flat upward facing surface having a hole for receiving a threaded screw for securement of the handlebar, method comprising:
