Abstract
Abstract Stabilizing apparatus for the front end of a motorcycle has a pair of forwardly declining fins adjustably attached to the front forks. In another embodiment, a single fin is supported over and spaced from the front wheel. Pressure of relative wind on the fins produces downward force on the forks which tends to hold down the front end of a motorcycle.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
133 words
Motorcycle stabilizing apparatus for a front end of a motorcycle having a frame, a rear wheel rotatably mounted at the rear of the frame, a fork rotatably mounted at the front of the frame, a front wheel mounted within the fork, comprising air deflection means for creating a downward force on the fork and the front wheel by the passage of air over the deflection means, said deflection means comprizing a forwardly declining fin means extending laterally outwardly a substantial distance from the longitudinal plane of said front wheel and attachment means connected to the air deflection means and adapted for being connected to the fork for holding the air deflection means on the fork and for transferring downward force from the deflection means to the fork and front wheel of the motorcycle.
Claim 2
Dependent Claim
133 words
Motorcycle stabilizing apparatus for a front end of a motorcycle having a frame, a rear wheel rotatably mounted at the rear of the frame, a fork rotatably mounted at the front of the frame, a front wheel mounted within the fork, comprising air deflection means for creating a downward force on the fork and the front wheel by the passage of air over the deflection means, said deflection means comprizing a forwardly declining fin means extending laterally outwardly a substantial distance from the longitudinal plane of said front wheel and attachment means connected to the air deflection means and adapted for being connected to the fork for holding the air deflection means on the fork and for transferring downward force from the deflection means to the fork and front wheel of the motorcycle.
Claim 3
Dependent Claim
40 words
Apparatus of claim 1 wherein the attachment means further comprises adjustment means connected to the deflection means and adapted for being connected to the fork for adjusting the deflection means with respect to the fork for varying downward force thereon.
Claim 4
Dependent Claim
22 words
Apparatus of claim 1 wherein the deflection means comprises a plurality of fins symmetrically positioned on opposite sides of a front wheel.
Claim 5
Dependent Claim
24 words
Apparatus of claim 1 wherein the deflection means comprises first and second forwardly declining fin means mounted on opposite sides of a front wheel.
Claim 6
Dependent Claim
96 words
The apparatus of claim 4 wherein the attachment means comprises inward projecting pivot means connected to the fin means at a lower forward portion thereof, the pivot means having mounting means adapted for connection to a lower forward portion of a wheel-mounting fork, and wherein the attachment means further comprises inward extending adjusting means haviNg an arcuate portion centered around the pivot means and a locking portion for connecting to the arcuate portion and having mountings at inward termini of the adjustment means for attaching the adjustment means to portions of fork above the pivot means.
Claim 7
Dependent Claim
22 words
The stabilizing apparatus of claim 1 wherein the deflection means comprises a plate having a downward curve adjacent a forward portion thereof.
Claim 8
Dependent Claim
21 words
The apparatus of claim 1 wherein the stabilizing apparatus comprises an elongated corrugated plate having corrugations running in a longitudinal direction.
Claim 9
Dependent Claim
19 words

Claim 10
Dependent Claim
44 words
Apparatus of claim 1 wherein the attachment means further comprises strut means adapted to be connected to the fork and connected to air deflection means for holding the air deflection means in a position over and spaced from the front wheel of the motorcycle.
Claim 11
Dependent Claim
29 words
Apparatus of claim 9 wherein the strut means comprises cooperative pairs of first and second struts adapted for connection to the fork on opposite sides of the front wheel.
Claim 12
Dependent Claim
43 words
Apparatus of claim 10 further comprising adjustment means connected to the air deflection means and adjustably connected to distal ends of the cooperative pairs of first and second struts for adjusting the declination of the deflection means for varying the downward force thereon.
Claim 13
Dependent Claim
21 words
