Why Riders Shop Mad Lads Moto

  • Orders placed today ship same-day or next-day across the lower 48 states!
  • Progressive Cornering Block Technology (PCBT): Built with Dunlop's patented block-within-a-block design on the shoulder knobs, drastically increasing cornering lean grip and sliding predictability when slamming through deep, blown-out ruts.
  • Advanced Carcass Flex System: Features a highly optimized tire carcass structure that expands impact absorption, smoothing out severe front-wheel braking bumps and lowering wrist fatigue.
  • Optimized Knob Distribution: Re-engineered block spacing increases center-to-shoulder block height synchronization, resulting in a predictable tracking transition from straight lines to maximum lean angles.
  • Pro-Level Mud Evacuation: Innovative mud evacuation channels built into the intermediate tread lines shed heavy clay or slick dirt instantly, preventing clogged lugs and keeping steering bite consistent.
  • Matching Sets Available: Complete your race weapon refresh by pairing this tracking front tire with our matching Geomax MX34 rear tires.

Confirmed Fitment Information

This standard-profile 80/100-21 tube-type (TT) front tire is designed explicitly to mount to a standard 21-inch front motocross wheel rim. Carrying a 51M load and speed rating, it safely supports up to 430 lbs at sustained track velocities up to 81 mph. Based on strict factory application charts, it is a universal, direct factory-spec replacement front tire for virtually all modern full-size dirt bikes, including:

  • Honda CRF250R / CRF250RX / CRF450R / CRF450RX: 2002 – 2027+ (Factory Front Size)
  • Yamaha YZ125 / YZ250 / YZ250F / YZ450F / YZ450FX: 1999 – 2027+ (Factory Front Size)
  • Kawasaki KX250 / KX250X / KX450 / KX450X: 2004 – 2027+ (Factory Front Size)
  • Suzuki RM125 / RM250 / RM-Z250 / RM-Z450: 2001 – 2027+ (Factory Front Size)

  • Note: Tailored specifically for front-wheel motocross tracks, off-road cross-country loops, and aggressive trail riding conditions. This is a tube-type (TT) bias tire footprint and requires a standard 21-inch heavy-duty inner tire tube or mousse insert for proper track deployment on laced or wire-spoked wheels.
