In India, demand for motorcycle with good comfort is increasing among the customers thereby the vibration reduction of two wheelers is key parameter for motorcycle manufacturers. In order to overcome the demand in the market, manufacturers are giving more importance to cost of the product by reducing the material. This results in the reduction of the life cycle of the vehicle models and drives the manufacturers to different product design philosophies and design tools, as one would expect. One of the performance factors that continue to challenge designers is that of vehicle vertical acceleration experienced by the motorcycle components. An essential tool in the motorcycle development process is the ability to quantify the durability of the component. This paper main objective is to increase the life of the motorcycle front fender through virtual simulation, on road testing and laboratory testing using NVH tool.

Testing, validation & evaluation are vital factors in terms of defining vehicle reliability and durability. Setting the correct ignition timing is crucial in the performance of the engine. It affects many variables including engine longevity, fuel economy, and engine power. It needs to be measured & controlled such that vehicle performance can be improved. Sparks occurring too soon or late in the engine cycle are often responsible for excessive vibrations and even engine damage. Today's spark-advance controllers are open-loop systems that measure parameters that affect the spark-advance setting and compensate for their effects. A closed-loop scheme instead measures the result of the actual spark advance and maintains an optimal spark-advance setting in the presence of disturbances. Attempt has been made in our endeavor to develop an embedded system device which can be used hands-on to measure the ignition timing with respect to T.D.C.

The main challenge that arises in the design of a motorcycle frame is its effect on the functionality on the vehicle, its effect on ride comfort and its durability. While functionality and ride comfort due to frame can be evaluated by subjectively testing it before the product reaches customer, evaluation of its durability is a complex process. This work is an investigation of the frame body of a 100 cc vehicle in India. These vehicles are subjected to endurance tests on a rough road at vehicle level to quantitatively evaluate their frame durability. However, such tests require significant time and cost, so an attempt has been made to develop a virtual rough road simulator to extract forces involved in it and testing the frame at component level with those loads on a test rig. Also durability results were compared and analyzed with the track data and frame test rig.
