The Kenda Millville II 120/80-19 Rear Tyre is the go-to choice for riders who demand uncompromising grip, stability, and performance in soft to intermediate terrain. With its beefy profile, enhanced tread design, and race-tested durability, this tyre dominates in high-torque conditions — whether you’re pushing a full-size 450cc MX bike or a tuned electric beast.
✅ This is a wide, heavy-duty rear motocross tyre, ideal for high-power platforms like the Sur-Ron Storm Bee, Ultra Bee (19" mod), or full-size 250cc–450cc MX bikes. Delivers an ultra-stable ride and massive traction on loam, ruts, and soft terrain.
✅ Wider Contact Patch: The 120 profile offers maximum surface grip and straight-line drive, perfect for heavy or high-horsepower machines.
✅ Aggressive, Reversible Tread Design: Widely spaced knobs with deep lugs bite hard and clean quickly — and the directional pattern can be reversed for extended wear.
✅ Reinforced Cornering Stability: The beefy shoulder knobs are engineered for hard-leaning confidence and corner exit grip.
✅ Built for Abuse: Durable 4-ply bias construction resists punctures and knobs tearing under torque loads.
✅ Soft to Intermediate Terrain Mastery: Performs best in loam, sand, and soft-packed tracks, yet remains effective when conditions start to firm up.
✅ Race-Proven Compound: Formulated for maximum traction and consistent performance in demanding environments.
✅ Motocross Racing: Ideal for full-size MX bikes and electric motocross setups that run 19" rear wheels.
✅ High-Torque Electric Builds: Suits Sur-Ron Ultra Bee / Storm Bee mods or Alta MX platforms with enhanced torque delivery.
✅ Loamy or Mixed Trail Riding: Gives confidence where other tyres spin, chunk, or wash out.
