The Kenda K777F Knarly front tire is designed for motocross and off-road powersports applications where dependable traction, predictable handling, and durable construction are essential. Its Knarly tread design helps provide confident grip across loose dirt, hard-packed terrain, and changing trail conditions, making it a practical choice for riders who demand consistent front-end control.

Built with a 6-ply rating and a load index of 54, the Kenda K777F balances strength and performance for demanding off-road use. The R speed rating supports speeds up to 106 mph under applicable conditions, while the tube-type construction is compatible with wheels designed for inner tubes. The 21-inch front wheel fitment is commonly used on motocross and off-road motorcycles, but riders should verify the manufacturer’s recommended tire size and application before installation.

This Kenda Knarly front tire features a black sidewall and a non-directional design intended to provide versatile handling across a range of off-road surfaces. It is supplied as one tire and does not include an inner tube, rim strip, mounting hardware, or installation services. Proper mounting, inflation, and inspection should be completed by a qualified tire professional. Always follow the motorcycle manufacturer’s specifications for fitment, load capacity, operating speed, and tire pressure.
