Abstract: A clutch cable lever operating system having a cable adjusting mechanism including a clamp for mounting the system on the handlebars of a motorcycle. The clutch cable lever fulcrum mounting flange to allow more or less free travel when the cable operating lever is used. The clutch cable adjusting mechanism is comprised of a coarse sleeve threaded into a cable adjusting cylinder that abuts the end of a cable outer sleeve. A manually adjusted threaded star nut or thumb wheel is fitted in a slot in the cable adjusting cylinder and threads on the coarse threaded sleeve. Rotation of the threaded star nut or thumb wheel incrementally extends or retracts the coarse threaded sleeve abutting the end of cable to adjust the slack that occurs when clutch plates expand due to heat. A resilient washer in an annulus intersecting the threads in the star nut or thumb wheel prevents free movement of the star nut on the coarse threaded sleeve to maintain the adjusted position.

Abstract: A tubular hand grip fits on and over the end of the cycle handle. It has a peripheral outer surface that is grasped by the hand. An external flange is located adjacent to an end of the grip to limit the axial movement of the hand. A blade projects from the outer surface, and extends as a fragment of a helix toward the flange, increasing in lateral dimension as it goes. It preferably terminates at a gap in the flange. The thumb can be laid against the blade in a comfortable position to be stabilized and located there. The grip is preferably so proportioned that the first finger of the hand can be brought against the other side of the blade so the thumb and first finger exert an efficient gripping action that requires only minimal physical effort.

Abstract: A pair of guards for the knee and shin of the left leg and of the right leg of a user. Each guard has a shell-like knee protector and a shell-like shin protector. The protectors of each guard are joined by a pair of hinge pins whose hinge axes are common, and which axis slopes upwardly as it extends away from a vertical axis between the legs of a standing user.

Abstract: The invention is a garment to support and to clothe portions of the body during energetic activities such as motorcross riding.
