The headstock assembly includes multiple headstock components that are welded to the frame. The design of the headstock assembly increases the surface area of the headstock assembly that is welded to the frame to increase rigidity. ## Claims ### Claim 1 A motorcycle frame comprising: a headstock assembly shaped for insertion of a steering stem, the headstock assembly formed to include a plurality of extensions that extend towards a rear of the motorcycle frame; and a plurality of side panels, wherein the extensions of the headstock assembly are welded to the plurality of side panels and the welds extend towards the rear of the motorcycle frame. ### Claim 2 (depends on 1) The motorcycle frame of claim 1 wherein the headstock assembly comprises a top headstock portion and a bottom headstock portion, the top head stock portion welded to the bottom headstock portion. ### Claim 3 (depends on 2) The motorcycle frame of claim 2, wherein the top headstock portion includes a top end and a bottom end, the top end including a hole for the steering stem. ### Claim 4 (depends on 3) The motorcycle frame of claim 3, wherein a side surface of the top headstock portion located between the top end and the bottom end of the top headstock portion is cylindrically shaped. ### Claim 5 (depends on 4) The motorcycle frame of claim 4, wherein the top headstock portion includes a hollow cavity opposite the side surface of the top headstock portion. ### Claim 6 (depends on 4) The motorcycle frame of claim 4, wherein the plurality of extensions include a first extension and a second extension that extend from the top end of the top headstock portion towards the rear of the motorcycle frame. ### Claim 7 (depends on 6) The motorcycle frame of claim 6, wherein the first extension and the second extension are triangular in shape and form a u-shaped curve at an intersection between the first extension and the second extension. ### Claim 8 (depends on 7) The motorcycle frame of claim 7, wherein the bottom head stock portion includes a top end and a bottom end, the bottom end including a hole for the steering stem. ### Claim 9 (depends on 8) The motorcycle frame of claim 8, wherein the bottom end of the top headstock portion is welded to the top end of the bottom headstock portion and wherein the hole included in the top headstock portion is aligned with the hole included in the bottom end of the bottom headstock portion. ### Claim 10 (depends on 9) The motorcycle frame of claim 9, wherein a side surface of the bottom headstock portion located between the top end and the bottom end of the bottom headstock portion is cylindrically shaped. ### Claim 11 (depends on 10) The motorcycle frame of claim 10, wherein the bottom headstock portion includes a hollow cavity opposite the side surface of the bottom headstock portion. ### Claim 12 (depends on 10) The motorcycle frame of claim 10, wherein the plurality of extensions including a third extension and a fourth extension that extend from the bottom end of the bottom headstock portion towards the rear of the motorcycle frame. ### Claim 13 (depends on 12) The motorcycle frame of claim 12, wherein the third extension and the fourth extension are triangular in shape and form a u-shaped curve at an intersection between the third extension and the fourth extension. ### Claim 14 (depends on 13) The motorcycle frame of claim 13, wherein the plurality of side panels comprise a first side panel and a second side panel, the first side panel and a second side panel each including a top surface and a bottom surface. ### Claim 15 (depends on 14) The motorcycle frame of claim 14, wherein the first extension and the second extension of the top headstock portion are welded to the top surfaces of the first side panel and the second side panel, and wherein the third extension and the fourth extension of the bottom headstock portion are welded the bottom surfaces of the first side panel and the second side panel. ### Claim 16 (depends on 14) The motorcycle frame of claim 14, wherein the first side panel and the second side panel each include a joining edge and wherein the joining edges of the first side panel and the second side panel are welded together. ### Claim 17 (depends on 16) The motorcycle frame of claim 16, wherein the headstock assembly encloses the joining edges of the first side panel and the second side panel. ### Claim 18 (depends on 14) The motorcycle frame of claim 14, wherein the first side panel includes a reinforcing bridge extending from the top surface of the first side panel and the second side panel includes a reinforcing bridge extending from the top surface of the second side panel. ### Claim 19 (depends on 18) The motorcycle frame of claim 18, wherein the reinforcing bride of the first side panel and the reinforcing bridge of the second side panel are welded together. ### Claim 20 A method of manufacturing a motorcycle frame comprising: providing a first side panel and a second side panel each including a top surface, a bottom surface, and a joining edge; welding together the joining edges of the first side panel and the second side panel; providing a headstock assembly including: a top headstock portion comprising a top end, a bottom end, and a plurality of first extensions that extend from the top end of the top headstock portion towards a rear of the motorcycle frame; a bottom headstock portion comprising a top end, a bottom end, and a plurality of second extensions that extend from the bottom end of the second tubular headstock portion towards the rear of the motorcycle frame; welding the plurality of first extensions of the top headstock portion to the top surface of the plurality of side panels; welding the plurality of second extensions of the bottom headstock portion to the bottom surface of the plurality of side panels; and welding the bottom end of the top headstock portion to the top end of the bottom headstock portion.
