Another group of riders that prefer four wheelers from this class are those who are physically smaller than the typical adult riders who prefer to keep their speed at a casual pace. Yet tough trail situations, such as overcoming big mud bogs or boulder fields, quickly tax these machines beyond their limits. Utility ATVs. Utility ATVs are by definition designed primarily for heavy duty work, such as hauling cargo on the front and rear racks, pulling a trailer or farm implement or pushing a plow blade. Thats why these machines have become so popular among people who own large amounts of land. A number of industries, law enforcement officers and service personnel also use this type of ATV, and theyve been a favorite of hunters, campers and fisherman since their inception in the mid 1. Utility quads have typically been regarded as sluggish handling behemoths with slow, but powerful, engines and a limited amount of suspension travel. But that has changed. Today, utility four wheelers are built to be fun and comfortable on the trails. When the going gets rough in the mud, rocks or steep hillclimbs, modern utility quads typically come through like champs. They have a high ground clearance and get great traction. There also dozens of extra features that can be found on utility quads, such as storage boxes, auxiliary electrical outlets, removable headlights, independent rear suspension and liquid cooled engines. Sport Utility ATVs. The sport utility category has probably done more than any other to increase the popularity of four wheelers. These machines combine the working capabilities of utility quads with the sporting characteristics of the performance and racing ATVs. Because of their flexibility, these machines are offered in a wide array of models offered year after year and are often the best sellers. Sport utility quads can be looked at basically in two different ways You can describe them as sport machines with racks, a trailer hitch and 4. WD or you could say theyre utility quads with faster engines and longer travel suspension. In fact, when you look under the skin of many of these sport utility ATVs, youll find that the manufacturers actually based their original designs for these quads on already existing sport or utility models. The best part of these machines is that you literally can spend the morning mowing the lawn with your quad and then take the same machine out for a fast afternoon trail ride, tackling jumps and churning out big broadslides. Sport ATVs. The machines that fit into this category were built with one goal in mind funSport ATVs typically feature peppy engines, long travel suspension, a relatively light overall weight and great handling for both the track and trail. Sport four wheelers are great at jumping, hitting the rough stuff, sliding around corners and popping wheelies. Experienced riders can fly down the trails at a quick pace that keeps them on their toes and gives them plenty of exercise. Sport quads also have a racier, more aggressive look to them when compared to utility or sport utility ATVs. In fact, modified sport quads are popular in the beginner classes at motocross and TT races and can be raced nearly stock in cross country events. Most sport four wheelers rely on a five speed transmission with a manual hand controlled clutch. This makes them more challenging to ride than the automatic models, but in the long run the shifting skills youll learn riding them will come in quite handy if you ever want to go racing or step up to a machine in the high performance category. This class has diminished greatly over the past few years, but a wide variety of options exists on the used market. Two Up ATVs. Two Up ATVs started appearing on the scene in 2. Canadian manufacturer Bombardier, now Can Am, first introduced this type of ATV and both Arctic Cat and Polaris have followed suit. Two Up ATVs typically feature a slightly longer wheelbase for added stability, a second, slightly raised seat with grab bars for the passenger and a second set of floorboards or footpegs.

To keep engines from overheating, air cooled powerplants rely on the simple and age old method of having external cooling fins built right on to the cylinder. The engines are usually positioned in the ATV so that as much air as possible flows over the cooling fins while the quad is in motion. Liquid cooled systems also known as water cooled, even though the coolant is actually a mixture of anti freeze and water are considerably more efficient at keeping the engine temperatures down. The system works by flowing the liquid coolant from a radiator mounted on the frame to the hollow channels surrounding the cylinder. Its pretty much the same setup that youll find in cars. Many ATVs also have an auxiliary fan that blows on the radiator to further cooling. The fan comes in handy when the quad is traveling at slow speeds, such as during lawn mowing or farm implement work. A cooler running engine is better in several ways. One is that power delivery stays consistent and strong another is that the overall life of the engine is increased, as well as the time span between overhauls. Overheated engines strain parts and decrease the effectiveness of the engine lubricants. Also, a hot ATV engine can be quite a nuisance for the rider, especially when your quad radiates heat right onto your legs. Electronic Fuel Injection. The vast majority of sportutility quads now feature electronic fuel injection EFI, similar to the systems found in cars. Changing Oil Manual Atv Yamaha Wolverine© 2017
