2003 Suzuki LTZ400

The of the QuadSport Z400 engine sound familiar since it is on the well-proven DR-Z400 Suzuki powerplant. The QuadSport Z uses Cooling to maintain optimum operating temperature and minimize loss due to engine heat. Cooling is especially effective on engines that operate at high RPM.

Radiator on the QuadSport-Z was chosen for it excellent abilities. Radiator placement with the Dry Sump lubrication allows for optimum engine and placement to keep a low center of The 398cc engine delivers a torque curve and a strong range from 3,000rpm to

The engine is composed of an aluminum-alloy, Suzuki#65533;s own race-proven nickel-phosphorus-silicon-carbide known as SCEM.) oversquare, four-…, liquid-cooled, DOHC with four valves by cam lobes riding directly on tappets. The cylinder head a narrow, 28 degree included angle for a compact, efficient chamber, with an 11.3:1 ratio.

This narrowed valve allows the use of a straighter intake between the 36mm Mikuni and the cylinder head, which in improves charging efficiency. The themselves are relatively large, intakes and 29mm exhausts, all 5mm stems to improve port The valve springs have retainers that are more and lighter than conventional springs and steel retainers.

The alloy cylinder reduces and improves heat transfer, tighter, more efficient clearance. A counterbalance shaft vibration, while an automatic cam tensioner and electric CDI ignition simplify routine maintenance. theengine lower in the frame of a slightly angled cylinder and dry-sump lubrication system for a compact design.

We loved the amount of power generated by the 400 throttle response we very Our test of the Z400 included winding wooded trails plenty of ruts and small we also encountered miles of fire roads. The quad is as as it looks, weighing just 168 (370 pounds) dry.

The LTZ400 excelled no matter the terrain characteristics were but we did enjoy an aggressive ride on any of the fire roads. The engines carried threw the complete RPM which topped out at around We spent some time with Suzuki representatives the engines future, we asked like how strong is the bottom

Does the engine have durability to be modified? The answers we were all positive and we#65533;re your going to see some trick modified versions of the 400 in the near future. Suzuki has introduced a complete set of exhaust to increase engine performance.

Suzuki#65533;s own start-in-gear system the engine to be started in any gear the left clutch lever which is pretty typical of any shifting model.


The chassis features a rigid, high-tensile steel-alloy frame and subframe. The suspension is giving the rider confidence catching air or hopping over logs on the trails. Independent front suspension with coil-cover shocks delivers (8.3inches) of wheel travel.

The swingarm rear suspension features a single, fully-adjustable shock and produces 231mm inches) of wheel travel. The Preload feature gives the the ability to apply more to the spring if the ride feels too or less tension if the ride stiff. The Adjustable Damping lets the rider fine the suspension for the surface and/or a ride.

Damping helps the speed that the shock compress and extend. When you the compression and rebound damping you are adjusting the oil flow through the More compression damping slow the compression of the shock and rebound damping will the rebound (extension) of the shock. is 1,245mm (49.0 inches) 262mm (10.3 inches) of clearance.

Standard equipment includes a front bumper and high-impact-plastic plate. The skid plate is than conventional skid eliminating corrosion, dents and easily over terrain spots. The double, serrated footpegs are vented for maximum and reduces mud build-up.

If your for maximum traction and performance the Z400 comes completely with standard aluminum-alloy 10.0 x 5.50-inch front and 9.0 x rear, carrying Dunlop AT 22 x 7 front radials and AT 20 x 10-9 radials.
