The Suzuki Quadsport LT230S (commonly referred to as the LT230) was the first sport variety quad

All-terrain vehicle

An all-terrain vehicle , also known as a quad, quad bike, three wheeler, or four wheeler, is defined by the American National Standards Institute as a vehicle that travels on low pressure tires, with a seat that is straddled by the operator, along with handlebars for steering control...

 to hit the market in 1985. It is powered by an overhead cam 2-valve 229 cc 4-stroke

Four-stroke cycle

A four-stroke engine, also known as four-cycle, is an internal combustion engine in which the piston completes four separate strokes—intake, compression, power, and exhaust—during two separate revolutions of the engine's crankshaft, and one single thermodynamic cycle.There are two...

 single-cylinder engine. It has a 5-speed manual clutch / manual shift drive train

Powertrain

In a motor vehicle, the term powertrain or powerplant refers to the group of components that generate power and deliver it to the road surface, water, or air. This includes the engine, transmission, drive shafts, differentials, and the final drive...

 with reverse. Final drive is by 520-pitch chain. It features hydraulic disc brake

Disc brake

The disc brake or disk brake is a device for slowing or stopping the rotation of a wheel while it is in motion.A brake disc is usually made of cast iron, but may in some cases be made of composites such as reinforced carbon–carbon or ceramic matrix composites. This is connected to the wheel and/or...

s front and rear, and independent double A-frame front suspension. The rear is a solid axle

Live axle

A live axle, sometimes called a solid axle, is a type of beam axle suspension system that uses the driveshafts that transmit power to the wheels to connect the wheels laterally so that they move together as a unit....

. All the shocks are preload adjustable. The LT230 features a side-kick style starter, a feature not commonly seen on any kick start

Kick start

Kick start refers to a method of starting an internal combustion engine by pushing a ratcheting lever with one's foot. Kick start mechanisms were almost universally a part of motorcycle engines before the mid-1970s, and were phased out of production over the next twenty years or so as electric...

 bike. In 1987, Suzuki released a slightly altered version known as the LT230E. It featured a semi-auto transmission and electric start. After the LT230S's discontinuation in 1988, the LT230E remained in production until 1993. The quad that replaced the LT230S was the LT250S. It featured an almost identical engine with a slightly bigger bore and 4th gear ratio

Gear ratio

The gear ratio of a gear train is the ratio of the angular velocity of the input gear to the angular velocity of the output gear, also known as the speed ratio of the gear train. The gear ratio can be computed directly from the numbers of teeth of the various gears that engage to form the gear...

. The suspension on the LT250S is progressive rate with more travel. The LT250S is also wider and longer.
