SPEED & PERFORMANCE PROFILE

Parent-Adjustable Speed Control for Progressive Skill Development:

The KFX 90 is designed with progressive skill development in mind. Parental controls include a keyed ignition to help address unsupervised use, as well as speed controls with a throttle-limiting screw to restrict throttle movement, and a collar in the automatic Continuously Variable Transmission (CVT) that can be removed to increase speed as the rider gains experience, allowing the KFX®90 to grow with the rider .

This two-stage speed adjustment system provides:

• Stage 1 (Beginner): Throttle-limiting screw engaged, CVT collar in place – lower, safer speed range suitable for first-time riders
• Stage 2 (Experienced): Speed controls fully opened as rider demonstrates capability – increased performance for more confident young riders

Reliable 90cc Engine:

The KFX 90 is powered by an 89.9cc air-cooled, 4-stroke single-cylinder engine that produces smooth and predictable power for young, developing riders . Engine highlights include:

• Electric start with keyed ignition for simple, reliable starting
• Back-up kick-starter ensures the fun doesn’t stop if the battery runs low
• SOHC design with 2 valves for efficient, reliable operation
• Carbureted fuel system (Keihin PTE16) for simple maintenance
• Maximum power of 6.5 PS at 7,500 rpm

Automatic CVT Transmission:

The Continuously Variable Transmission (CVT) with centrifugal clutch provides seamless, automatic operation—no shifting required . Young riders can focus on the basics of steering, throttle control, and braking without the complexity of manual gear changes.

Automatic Clutch:
The automatic centrifugal clutch engages smoothly as engine speed increases, making it easy for young riders to get moving without stalling.

Protection

• GET A GRIP: Full coverage floorboards with slip-resistant footing contribute to increased grip and helps young riders control their ATV when riding while in a standing position. Effective mud protection keeps the engine running at a cooler temperature and keeps dirt and debris from building up near the engine.

Styling

• RIDE WITH SWAGGER: Front LED accent lights, and LED taillights add to the already race-inspired bodywork. Additionally a tall design of the front fenders conveys a strong sporty off-road performance look.

Suspension

• SMOOTH OUT YOUR RIDE: Independent A-arms in the front and swingarm rear suspension soak up bumps for a smooth ride and contribute to sporty handling.
