Manco Go Karts – For Go Kart Elitists
Let me start by saying that Manco Go Karts are probably not ride on toys for younger kids unless he or she is the next Dale Earnhardt or Danica Patrick. That said, when it comes to go karts, Manco go karts might be the best choice in ride on cars for older kids.
When most people think of go karts, they think of something made of old spare parts — a beat up 3 horsepower engine from the old lawnmower, scrounged up mini-bike tires, an ugly and bare, primer gray steel-framed chassis… (and we love them!). Manco go karts are a giant leap above those minimalist salvage job go karts of the past. These babies are deluxe!
American Sportworks (formerly Manco Powersports) has been making quality go-carts since 1970. Their Manco go karts have features like suspension, roll bars, rack and pinion steering and contoured seats.
Manco Go Karts Quantum
The Quantum by American Sportworks personifies power, style and pure fun.
The Quantum from Manco Go Karts is a sophisticated, high performing vehicle that has the features and power needed needed for driving on virtually any terrain. Teenagers and adults alike will love how it handles. Its got a two wheel auto torque converter drive train and air-cooled 150 cubic centimeter, 9.9hp motor that gives the Helix plenty of juice to handle hilly, muddy, sandy driving — and the engine runs relatively quiet as well. With its electric starter, no pull cord is needed. Top speed is 39mph but with an optional speed reducing kit, you can cap the speed at around 20mph if need be. Safety features include dydraulic disc brakes, 3-point seat belts, and a roll bar. The Quantum is a two-seater with adjustable, bucket seats that are both stylish and comfortable and seatbelts for both driver and passenger. It comes equipped with high traction tires, Rack & Pinion steering, independent front and semi-independent rear suspension, reverse gearbox and enclosed drive train.
