  The Polaris Scrambler is a four-wheel drive all-terrain vehicle (ATV) with a two-stroke engine. It features high torque, which means it can handle hills and adverse terrain more easily than other ATVs. It went out of production in 2001 when it retailed for around $5,000.
  
  

Dimensions

• The 2001 Polaris Scrambler 400 is 65 inches long, just over 4 feet tall and just under 4 feet wide. It weighs 480 pounds, and its wheelbase follows the theme of the height and width--around 4 feet. The engine is 378 ccs, which means it holds a total of 378 cubic centimeters in its two cylinders. The fuel tank holds 4 gallons.
  
  

Engine

• The engine is two-stroke, which means it has two pistons firing in opposition to one another. It is also liquid-cooled and counterbalanced. A counterbalanced engine is an engine whose pistons have weights on the non-firing sides. This makes them retract to their starting position quicker and generally makes them more efficient. The engine also has an electric start, negating the need for a kick-start. It is lubricated through oil injection.
  
  

Brakes and Suspension

• The front brake is a disc brake while the rear brake is a foot brake. The front brake is a single-lever, made up of only a hydraulic disk. The rear brake, on the other hand, has two levers, a hydraulic piston caliper and a disc brake. The front suspension is a MacPherson system with 8 inches of travel. This means it allows the front wheels 8 inches of give, thus reducing the shock on the rest of the ATV and on the driver. The rear suspension is a swing arm with 10 inches of travel, which means that the rear shocks are cushioned more effectively than the front shocks.
