Kawasaki KFX90 2010 - User Manual

The Kawasaki KFX90 is an All-Terrain Vehicle (ATV) designed for recreational off-road use, primarily for children aged 12 and older. This owner's manual provides comprehensive information on its safe operation, maintenance, and storage, with a strong emphasis on rider safety and parental supervision.

Function Description:

The KFX90 is a motorized vehicle intended for off-road riding on various terrains. It is equipped with an engine (70 cc or greater, but specifically a 90 cc engine for this model, as indicated by the "KFX90" designation and age recommendations), a belt drive transmission, and a braking system. Its primary function is to provide an enjoyable off-road riding experience for young riders, while incorporating safety features and guidelines to minimize risks. The vehicle is designed to be operated by a single rider and is not intended for carrying passengers or towing trailers.

Important Technical Specifications (derived from the manual's content):

• Engine Size: 90 cc (implied by "KFX90" and the age recommendation for ATVs greater than 90 cc).
• Minimum Operator Age: 12 years old. A child under 12 years old should never be allowed to operate this vehicle. For ATVs with engines greater than 90 cc, the minimum age is 16 years old, but the KFX90 is specifically for 12 years and older, implying it falls within the 70-90 cc range for this age group, or that the 90cc engine is considered appropriate for 12+ with proper training and supervision. The manual explicitly states "A child under 12 years old should never be allowed to operate this vehicle" and also "A child under 16 years old should never operate an ATV with engine greater than 90 cc." This suggests the KFX90, being a 90cc model, is targeted at the 12-16 age group, requiring adult supervision.
• Tire Type and Size: Specific types and sizes are specified in the manual, and proper inflation is crucial for handling. A tire pressure gauge is included in the tool kit.
• Braking System: Includes front and rear brakes, with specific instructions for their operation and maintenance. Wet brakes may have reduced stopping ability.
• Transmission: Belt Drive Transmission.
• Fuel System: Requires specific fuel types and has a fuel tap. Refueling must be done with the engine off in a well-ventilated area, away from flames or sparks.
• Ignition System: Features an ignition switch, engine stop switch, and starter switch.
• Starting Mechanism: Equipped with a kick starter.
• Safety Features: Includes an adjustable throttle limiter for new riders, which can be adjusted to gradually increase maximum speed. The vehicle does not have a headlight, meaning it should never be ridden at night.

Usage Features:

• Rider Readiness Assessment: Parents are advised to evaluate a youngster's physical size, athletic ability, and mental/emotional maturity before allowing them to ride. This includes checking for at least three inches (8 cm) of clearance between the ATV seat and the rider's "seat of the pants" when standing on the footboards, and ensuring comfortable reach and operation of all controls.
• Training Requirement: Operation requires proper instruction, and beginners should take a certified training course. Contact information for training courses is provided (1-800-887-2887).
