The purpose of our project was determining the various new concepts of modelling and adding and removing features. We took old bike, wanted to customize it and going to focus on the performance side. Most of the part are taken from the old bike rest of the parts are designed and manufactured. It is not a commuter using purpose it is for street racing. We make a custom motorcycle firstly we have found raw material for frame designing in order to replace existing frame, and we are taken hub steering system for better handling and wide tyre of wheels for better gripping with road with advance anti-lock braking system. Then we have done different type of customization regarding our project. Keywords: modeling, design, frame and handling 1. Introduction 2.4 Article The project was a customized looking bike little bit similar Vietnamese Rider Creates His Own Custom Bike, By to sports bike. A dual-sport motorcycle is a type of street Damon Lowney, July 11th 2013. He built his own custom motorcycle that is designed for both on and off-road use. bike with Suzuki engine in its garage, so why can‘t we? So The terms all-road and dual-purpose are also used for this we are came to this project idea by building of our own… class of motorcycles. But it is not a commuter using purpose bike. Vehicle is a modified street-bike with a 150 cc liquid- 2.5 Article cooled DTSI engine. It contains a duel suspension at the centre of the vehicle with parallel manner.

This type of design is structurally stronger Customize motorcycle. We‘ve taken references from than any of the competitor's designs, And easier to control different customized bike. And further studied about engine, the bike at high speed and from this frame it less load on suspension and brakes. other section of bike. About this project we stroke different ideas at different 3.

External Combustion Engine. 2. Internal Combustion Engine. 1) Suction stroke 2) Compression stroke 1) External Combustion Engine 3) Power stroke Here, the working medium, the steam, is generated in a 4) Exhaust stroke boiler, located outside the engine and allowed in to the cylinder to operate the piston to do mechanical work. 2) Internal Combustion Engine In internal combustion engine, the combustion of fuel takes place inside the engine cylinder and heat is generated within the cylinder. This heat is added to the air inside the cylinder and thus the pressure of the air is increased tremendously. This high pressure air moves the piston which rotates the crank shaft and thus mechanical work is done. 3.2 Working Principle of I.C. Engine/ Four Stroke Figure 2: Four Stroke Cycle Engine Cycle Engine 3.3.1 Suction Stroke A mixture of fuel with correct amount of air is exploded in During suction stroke inlet valve opens and the piston moves an engine cylinder which is closed at one end. As a result of downward. Only air or a mixture of air and fuel are drawn this explosion, heat is released and this heat causes the inside the cylinder. The exhaust valve remains in closed pressure of the burning gases to increase. This pressure position during this stroke. The pressure in the engine forces a close fitting piston to move down the cylinder. The cylinder is less than atmospheric pressure during this stroke. movement of piston is transmitted to a crankshaft by a connecting rod so that the crankshaft rotates and turns a 3.3.2 Compression Stroke flywheel connected to it. Power is taken from the rotating During this stroke the piston moves upward. Both valves are crank shaft to do mechanical work. To obtain continuous in closed position. The charge taken in the cylinder is rotation of the crank shaft the explosion has to be repeated compressed by the upward movement of piston. If only air is continuously. compressed, as in case of diesel engine, diesel is injected at the end of the compression stroke and ignition of fuel takes Before the explosion to take place, the used gases are place due to high pressure and temperature of the expelled from the cylinder, fresh charge of fuel and air are compressed air. If a mixture of air and fuel is compressed in admitted in to the cylinder and the piston moved back to its the cylinder, as in case of petrol engine, the mixture is starting position. The sequence of events taking place in an ignited by a spark plug. engine is called the working cycle of the engine. The sequences of events taking place inside the engine are as 3.3.3 Power Stroke follows: After ignition of fuel, tremendous amount of heat is generated, causing very high pressure in the cylinder which 1) Admission of air or air-fuel mixture inside the engine pushes the piston downward. The downward movement of cylinder (suction). the piston at this instant is called power stroke. The 2) Compression of the air or air fuel mixture inside the connecting rod transmits the power from piston to the crank engine (compression). shaft and crank shaft rotates. Mechanical work can be taped 3) Injection of fuel in compressed air for ignition of the fuel at the rotating crank shaft. Both valves remain closed during or ignition of air-fuel mixture by an electric spark using a power stroke. spark plug to produce thermal power inside the cylinder (power). 3.3.4 Exhaust Stroke 4) Removal of all the burnt gases from the cylinder to During this stroke piston moves upward. Exhaust valve receive fresh charge (exhaust). opens and exhaust gases go out through exhaust valves opening. All the burnt gases go out of the engine and the 3.3 Four Stroke Cycle Engine (Petrol Engine) cylinder becomes ready to receive the fresh charge. During this stroke inlet valve remains closed. Thus it is found that In four stroke cycle engines the four events namely suction, out of four strokes, there is only one power stroke and three compression, power and exhaust take place inside the engine idle strokes in four stroke cycle engine. The power stroke cylinder. The four events are completed in four strokes of supplies necessary momentum for useful work. the piston (two revolutions of the crank shaft). This engine has got valves for controlling the inlet of charge and outlet 3.4 Engine Components of exhaust gases. The opening and closing of the valve is controlled by cams, fitted on camshaft. The camshaft is Internal combustion engine consists of a number of parts driven by crankshaft with the help of suitable gears or which are given below: chains. The camshaft runs at half the speed of the crankshaft.

CYLINDER: It is a part of the engine which confines the piston skirt. They control the distribution of lubrication oil in expanding gases and forms the combustion space. It is the cylinder and the piston. the basic part of the engine.
