US 10,865,756 B2 · Assisting a kick starter for reliable start and safety on a motorcycle

Abstract

A start assist system is configured to generate torsion load on an crankshaft of a motorcycle. The configurations include a hub adapted to couple with a kick start lever on a motorcycle, a load generating unit, the loading generating unit adapted to generate torsion on the hub, and circuitry to regulate operation of the load generating unit in response to a position of the kick start lever. The torsion load operates to assist an operator to kick-start the machine.

Dependent claims

A motorcycle, comprising:

a kick start lever;
a hub coupled with the kick start lever;
a pneumatic actuator coupled with the hub;
a sensor disposed in proximity to the hub and responsive to a position of the hub as actuated by the kick start lever,
wherein the pneumatic actuator applies torsion load to the hub in response to a signal from the sensor that corresponds with rotation of the kick start lever.
