Description
Uno Minda CH-7001 Chain Sprocket Kit R428H Size-120L/ 14T/ 45T(4H) for Yamaha Fazer, YBR 125, SS 125, Graffiti is a set of components used to transmit power and motion from a motorcycle or bicycle engine to the wheels. The kit typically includes one or more sprockets (also known as chainwheels), a chain, and sometimes other accessories such as a chain tool. The sprockets are circular gear-like components with teeth that engage with the links of the chain. The sprocket attached to the engine is called the front sprocket or countershaft sprocket, while the sprocket attached to the rear wheel is called the rear sprocket or wheel sprocket. The size and number of teeth on the sprockets determine the gear ratio, which affects the acceleration, top speed, and fuel efficiency of the motorcycle or bicycle. The chain is a flexible link of metal or plastic that connects the two sprockets and transmits the power and motion from the engine to the wheels. The chain needs to be properly tensioned and lubricated to prevent wear, noise, and damage to the sprockets and other components. A chain tool may be included in the kit to help install or remove links from the chain, adjust the length or tension of the chain, or replace worn or damaged components. The front sprocket is mounted on the engine’s output shaft, while the rear sprocket is attached to the rear wheel. The chain is then wrapped around the two sprockets, creating a loop that transfers power from the engine to the rear wheel.
