Chopper is a heavy motorcycle of impressive size with a lot of chrome parts, a teardrop-shaped gas tank, leather bags (trunks) on the sides. The saddle is stepped, the steps are moved forward, the steering wheel is close to the rider, the suspension is soft. Designed for a quiet comfortable ride on the track. The chopper is cramped in the city. Engines are usually high-torque and low-speed. The classic chopper has a narrow front wheel with a large diameter and a wide rear wheel with a reduced diameter.
Instructions
Step 1
First of all, decide on the manufacturer. American Harley Davidson is considered a classic chopper among motorcyclists. These are the trendsetters in chopper building. Japanese motorcycles very successfully copy American ones in appearance, but of better quality in manufacturing, more reliable and durable and with more advanced technical solutions and technologies.
Step 2
Next, you need to make a decision about the engine displacement. Low-volume choppers are more economical, lighter in weight and easier to operate for beginners. And their price is more attractive. But the bulk of consumers prefer large motors: the thrill of the trip is stronger and the resource is very large. The greatest demand is for choppers of the 750-1100 cc class. Larger engine displacement - for amateurs only. Poor consumers prefer the 400 cc class.
Step 3
The rear chopper wheel is driven by a propeller shaft. There are choppers with a chain or belt drive on the rear wheel, but for heavy machines, a cardan is preferable. When buying a used gimbal motorcycle, pay special attention to the wheel reducer and the condition of the oil in it. The chain is checked for wear and type of chain. If the chain is ordinary, its resource will be small, - an O-Ring type chain is required.
Step 4
The most common type of engine is a V-type, two-cylinder, liquid-cooled with two overhead camshafts. Other types are rarely used. When buying a used chopper, measure the compression (should be 0.8-1.0 MPa), check that there is no noise at idle.
Step 5
To check the power supply of a used motorcycle, accelerate to 100 km / h. Interruptions and dips in engine operation at this speed indicate a general contamination of the power system. Check for rust in the gas tank.
Step 6
The front chopper fork is often corroded. And the effects of front fork corrosion are much more severe than the effects of frame corrosion.
Step 7
The rear suspension can be with two shock absorbers or with one monoshock. Hang up the rear wheel and swing the swingarm to the sides. The beating of a pendulum means wear on its bearings. Choppers are equipped with non-adjustable non-separable shock absorbers. They are incredibly difficult to repair and expensive to purchase ($ 400 each).
