    Kenda 120/90-19 K774 IBEX Motocross Rear Tyre – Climb Anything, Conquer Everything

    The Kenda K774 IBEX 120/90-19 Rear Tyre is a high-performance soft-terrain tyre built for extreme enduro and hard enduro riders who demand relentless traction, flexibility, and grip. Engineered with a super-soft gummy compound and unique carcass design, the IBEX grips like a trials tyre while holding up to enduro punishment — making it ideal for slippery rocks, steep climbs, logs, and technical terrain.

     

    🏋️♂️ Weight: ~6.7 kg (14.8 lbs)

    ✅ This is a wide-profile, soft-compound rear tyre developed for extreme off-road and hard enduro riding — ideal for electric motos like the Sur-Ron Ultra Bee (19" mod), Storm Bee, and 250–450cc enduro builds needing maximum rear wheel traction.

    🗝️ Key Features:

    Super Soft Gummy Compound: Ultra-flexible rubber bites into rocks, logs, and roots — providing trials-like grip in technical sections.

    Ultra-Flexible Carcass: Designed to conform to terrain for traction in low-speed, high-torque situations without bouncing or deflecting.

    Deep Tread Blocks: Large, widely spaced knobs maintain traction and prevent mud buildup in soft and wet terrain.

    Extreme Off-Road Performance: Purpose-built for hard enduro, extreme climbs, and slippery conditions.

    Excellent Low-Pressure Control: Performs exceptionally well at low PSI for maximum footprint and traction.

    Bias-Ply Construction: Offers durability with flexibility — essential for crawling over rough terrain without tearing lugs.

    🏍️ Applications:

    Hard Enduro & Technical Trail: Excels in extreme off-road conditions where precision grip matters most.

    E-Moto Traction Builds: Matches the torque of high-power electric dirt bikes for unbeatable traction.

    Slippery / Technical Terrain: Grips confidently on rocks, roots, and loose climbs where other tyres spin out.

    🧠 How It Performs on Sur-Ron & Talaria

    Strengths

    • Incredible grip in wet, slippery, or rocky conditions

    • Flexes and conforms to terrain for technical climbing

    • Great match for e-moto torque at low RPMs

    • Delivers trials-like feel with dirt tyre durability

    ⚠️ Considerations

    • Soft rubber = faster wear on hardpack or aggressive throttle

    • Heavier than stock = slightly reduced responsiveness

    • Not DOT approved – off-road only (NHS)

     

    🏁 Terrain Performance on E-Moto / MX

    Surface Performance
    Rocks / Roots ⭐⭐⭐⭐⭐ – Exceptional crawling and grip
    Loam / Soft Dirt ⭐⭐⭐⭐☆ – Grippy and forgiving
    Mud / Sand ⭐⭐⭐⭐☆ – Wide knobs clear mud quickly
    Hardpack / Gravel ⭐⭐☆☆☆ – Soft compound may chunk or smear
    Pavement ⭐☆☆☆☆ – Not for street use
    Braking Control ⭐⭐⭐⭐☆ – Excellent rear bite at low speed

    🔧 Setup Tips

    Recommended PSI:

    • 8–10 PSI for extreme enduro

    • 11–13 PSI for trail/mixed terrain

    Best Front Pairing:

    • Kenda Equilibrium 90/90-21

    • K777F Enduro or Washougal II for aggressive trail fronts

    ✅ Best For:

    • Hard Enduro riders in wet, steep, or technical terrain

    • E-moto builders running torque-heavy controllers and seeking grip

    • Trail riders who prioritize traction over speed

    ❌ Not Ideal For:

    • Road or dual-sport riders

    • Flat, fast, or rocky hardpack terrain

    • Ultra-lightweight bikes without proper rim/tube setup

    💡 Pro Tip:

    Running the IBEX at low PSI with a rim lock or mousse insert turns your rear wheel into a claw that crawls over anything. It’s not just traction — it’s controlled propulsion in places you'd normally spin out.

    🏆 Grip Where Others Slip:

    The Kenda IBEX 120/90-19 delivers unrivaled performance for extreme riders. Whether you're tackling a wet rock garden or technical singletrack, it provides the confidence to power through without losing control.
