    SKU: EMOT-PRT-KEN-120-80-19-63M-K78-MIL-II-MOT-REA-TYR


    Kenda 120/80-19 K785 Millville II Motocross Rear Tyre – Built for Power and Precision

    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.

    🏋️♂️ Weight: ~6.9 kg (15.2 lbs)

    ✅ 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.

     

    🗝️ Key Features:

    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.

    🏍️ Applications:

    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.

    Sur-Ron Storm Bee 100/90-19 or 110/90-19 19 x 2.15" ✅ Excellent fit Matches wide rear swingarm clearance; optimal upgrade
    Sur-Ron Ultra Bee 90/90-18 (stock) 18 x 2.15" ⚠️ Requires mod Must switch to 19” rear rim; works well with 2.15–2.50"
    Sur-Ron Light Bee X 80/100-19 19 x 1.6–1.85" 🚫 Not recommended Too wide; clearance issues even with fender/swingarm mods
    Talaria Sting (MX3) 80/100-19 19 x 1.85" ⚠️ Tight fit May require mods for fender/suspension clearance
    Talaria XXX / R 70/100-19 19 x 1.6" 🚫 Too large Will not fit without full wheel and subframe changes

    🧠 How It Performs on Sur-Ron & Talaria

    Strengths

    • Best-in-class grip and cornering confidence for wide-rim, high-power setups

    • Larger knobs improve drive and braking bite

    • Built tough for e-moto torque without knob chunking

    • Self-cleaning tread ideal for muddy, loamy, or rutted tracks

    ⚠️ Considerations

    • Heavy-duty weight = less flickable than narrower profiles

    • Taller overall height (~27”) may raise rear ride height

    • Not DOT approved (NHS) → off-road use only

     

    🏁 Terrain Performance on E-Moto / MX

    Surface Performance
    Loam / Soft Dirt ⭐⭐⭐⭐⭐ – Elite-level grip and drive
    Mud / Sand ⭐⭐⭐⭐☆ – Wide tread clears fast
    Hardpack / Gravel ⭐⭐☆☆☆ – May wear fast under torque
    Pavement ⭐☆☆☆☆ – Not street legal
    Braking Control ⭐⭐⭐⭐☆ – Precise rear bite on soft terrain
