A two-wheeled vehicle, comprising: a front wheel;a rear wheel generally positioned in line with the front wheel along a longitudinal plane of the two-wheeled vehicle;a frame supported by the front wheel and the rear wheel, the frame including a cast frame member;a prime mover coupled to the frame and operably coupled to the rear wheel to power the rear wheel;a straddle seat supported by the frame, the straddle seat having a support surface; anda steering system rotatably coupled to the frame, the steering system including a steering post passing through an interior of the cast frame member of the frame, a first fork member positioned to a first side of the longitudinal plane and coupled to the front wheel, a second fork member positioned to a second side of the longitudinal plane and coupled to the front wheel, and at least one coupling member which couples the steering post to the first fork member and to the second fork member; wherein a steering axis defined by the steering post is angled upward relative to horizontal by a first angle and a fork axis defined by the first fork member is angled upward relative to horizontal by a second angle, the second angle being less than the first angle and both the first angle and the second angle being acute, wherein the steering post is coupled to the at least one coupling member at a first location of the at least one coupling member and the first fork member is coupled to the at least one coupling member at a second location of the at least one coupling member, the first location of the at least one coupling member being forward of the second location of the at least one coupling member. 3. The two-wheeled vehicle of claim 2, wherein the at least one coupling member includes a triple clamp and is positioned above the frame. 4. The two-wheeled vehicle of claim 3, further comprising handlebars which are supported by the triple clamp. 5. The two-wheeled vehicle of claim 1, wherein the two-wheeled vehicle may be configured in a non-fairing configuration and in a fairing configuration, the non-fairing configuration having a first center of mass and the fairing configuration having a second center of mass, in the fairing configuration the two-wheeled vehicle further including a fairing including a support supported by the frame, at least one body panel supported by the support and an instrument cluster supported by the support. 6. The two-wheeled vehicle of claim 5, wherein the steering axis is forward of the first center of mass. 7. The two-wheeled vehicle of claim 6, wherein the steering axis is rearward of the second center of mass. 8. A two-wheeled vehicle, comprising: a front wheel;a rear wheel generally positioned in line with the front wheel along a longitudinal plane of the two-wheeled vehicle;a frame supported by the front wheel and the rear wheel;a prime mover coupled to the frame and operably coupled to the rear wheel to power the rear wheel;a straddle seat supported by the frame, the straddle seat having a support surface; anda steering system rotatably coupled to the frame, the steering system including a steering post coupled to the frame defining a steering axis, a first fork member defining a fork axis positioned to a first side of the longitudinal plane and coupled to the front wheel, a second fork member positioned to a second side of the longitudinal plane and coupled to the front wheel, a first triple clamp which couples the first fork member, the second fork member, and the steering post together and a second triple clamp which also couples the first fork member, the second fork member, and the steering post together, a means for centering which centers the steering post in an opening in the second triple clamp, wherein the steering axis is angled relative to the fork axis. 9. The two-wheeled vehicle of claim 8, wherein the means for centering includes a coupler having a chamfered surface that rests against the second triple clamp and through the contact with the second triple clamp centers the steering post in the opening in the second triple clamp. 10. The two-wheeled vehicle of claim 8, wherein the means for centering includes a hat-shaped spacer which is placed over the steering post and is sized to center the steering post in the opening in the second triple clamp, the hat-shaped spacer keeping the steering post spaced apart from the second triple clamp. 11. The two-wheeled vehicle of claim 8, wherein the steering post is coupled to the first triple clamp a first location and the first fork member is coupled to the first triple clamp at a second location, the first location being forward of the second location. 12. The two-wheeled vehicle of claim 8, wherein the steering post is coupled to the second triple clamp a first location and the first fork member is coupled to the second triple clamp at a second location, the first location being forward of the second location. 13. The two-wheeled vehicle of claim 8, wherein the two-wheeled vehicle may be configured in a non-fairing configuration and in a fairing configuration, the non-fairing configuration having a first center of mass and the fairing configuration having a second center of mass, in the fairing configuration the two-wheeled vehicle further including a fairing including a support supported by the frame, at least one body panel supported by the support and an instrument cluster supported by the support. 14.
