TL;DR: In this article, an algorithm for finding the minimum-time trajectory for a constrained 1DOF vehicle model is developed, which is a point-mass vehicle constrained to follow a given path and subject to accelerations representative of more general vehicles.
Abstract: Producing a high-performance motorcycle prototype entails extensive engineering in which virtual prototyping plays an important role by reducing the number of physical tests that need to be performed during the design process. High-performance motorcycle maneuvering required in racing competitions is discussed. Various constraints that limit the performance of a motorcycle are focused upon. Motorcycle features - including engine power, tire forces, and wheelie and stoppie maneuvers - are reviewed. An algorithm for finding the minimum-time trajectory for a constrained 1DOF vehicle model is developed. This model is a point-mass vehicle constrained to follow a given path and subject to accelerations representative of more general vehicles. Examination of the idealized situation clarifies the dynamic features needed to find the minimum-time velocity profile. A detailed nonholonomic motorcycle model capturing gross vehicle motion and the associated contact forces is presented. A quasi-steady technique for approximating the velocity constraint and acceleration limits that are in play for the vehicle at each location along the desired path is developed. From the information obtained, an approximately optimal velocity profile is constructed and used to build an approximate motorcycle trajectory

TL;DR: In this paper, a stand for locking the front wheel of a vehicle, such as a motorcycle, in a stable position has been presented, and the stand has front and rear support mechanisms which are actuated by a ramp so that the weight of the motorcycle as it is rolled onto the ramp will actuate the rear supports to engage the tire at locations forward and rearward of the wheel axis of rotation.
Abstract: A stand for locking the front wheel of a vehicle, such as a motorcycle, in a stable position. The stand has front and rear support mechanisms which, in a preferred embodiment, are actuated by a ramp so that the weight of the front wheel of the motorcycle as it is rolled onto the ramp will actuate the front and rear supports to engage the tire at locations forward and rearward of the wheel axis of rotation.

15 May 2003TL;DR: In this article, an air bag that is configured to include portions that correspond to the rider motions generated in motorcycle accidents is provided. But the air bag is not designed to include a rider protection region at pitching which is formed in front of the rider in the pitching of the motorcycle around a front wheel due to the forward collision of the bike.
Abstract: An air bag apparatus is provided having an air bag that is configured to include portions that correspond to the rider motions generated in motorcycle accidents. The air bag apparatus has an air bag provided on a motorcycle and which includes a first expansion part which is expanded toward a rider protection region which is formed above a body constituent part of the motorcycle and in front of the motorcycle rider in the case of the forward collision of the motorcycle; and a second expansion part which is expanded toward a rider protection region at pitching which is formed in front of the motorcycle rider in the pitching of the motorcycle around a front wheel due to the forward collision of the motorcycle.

TL;DR: In this article, a three-wheeled motorcycle dolly adapted for use in conjunction with roll-back tow truck has wide wheel base and low elevation decking. Rigid eyes are provided along frame for strapping motorcycle in upright position to dolly.
Abstract: Three-wheeled motorcycle dolly adapted for use in conjunction with roll-back tow truck has wide wheel base and low elevation decking. Rigid eyes are provided along frame for strapping motorcycle in upright position to dolly. Convex wheel stop rigidly attached to front of dolly provides permanent chocking for forward wheel of motorcycle. On-loading and off-loading of motorcycle are accomplished by single person with aid of detachable ramp, and inclined push rails on sides of dolly.

TL;DR: In this paper, an anti-dive apparatus for a bicycle including a front wheel suspension, a rim brake, and a support for the rim brake is described. But the front wheel is not considered.
Abstract: Anti-dive apparatus for a bicycle including a front wheel suspension, a rim brake, and a support for the rim brake which moves the rim brake relative to the front bicycle wheel and the front wheel suspension responsive to application of an external force to the front bicycle wheel.
