    🦉What does the 'F' stand for?

     

    Yes, the "F" in K785F typically denotes a front tyre variant of the Kenda K7101 Millville II series. Front and rear motocross tyres are designed differently to meet the specific demands placed on them during riding.

    Tread Pattern: The front tyre, K7101, will have a tread pattern optimized for steering and braking. This pattern usually features tighter-spaced knobs and a directional design to improve front-end stability and cornering grip. The rear tyre, on the other hand, has a pattern more focused on providing traction and power delivery, with more giant, more spread-out knobs to dig into the soil.

    Width and Profile: Front tyres are generally narrower and have a taller profile than rear tyres. This helps in cutting through soft terrain and aids in making sharper turns. The rear tyres are more comprehensive to increase the contact patch for better traction during acceleration.

    Construction: The carcass construction might also vary, with front tyres often built to be slightly softer to absorb impacts and aid in comfortable steering, whereas rear tyres need to be more challenging to handle the torque and power output from the engine.

    Sidewall Stiffness: Front tyres might have a different sidewall stiffness to aid in handling characteristics, reduce flex during tight manoeuvres, and maintain stability at high speeds or under braking.

    While the K7101 and K7101F belong to the same tyre family and share many of the same materials and overall design philosophies, their specific constructions and tread designs are tailored to meet the distinct demands of front versus rear tyre applications in motocross. This specialisation ensures that each tyre performs optimally for its specific role on the bike.

    ⚡️ How It Works on Sur-Ron & Talaria Electric Bikes

     

    Model Stock Front Wheel Fitment Mods Required Notes
    Sur-Ron Light Bee X 70/100-19 (19”) ⚠️ Mod only Needs 21" front wheel swap Better rollover, but may need fender lift + fork check
    Sur-Ron Ultra Bee 90/90-19 (stock) Possible with mod 21” front rim + tyre swap Great for trail or MX if upgraded
    Sur-Ron Storm Bee 80/100-21 (stock) Direct fit None Stock size – perfect replacement or soft terrain upgrade
    Talaria Sting R / MX4 70/100-19 (stock) ⚠️ Mod only 21” front rim + fender lift Can work, but may impact steering geometry if too tall
    Talaria XXX 17” front Too big Not compatible 21” tyre is far too large for this chassis
    Stark VARG 80/100-21 (MX spec) Perfect fit None Designed for this exact size — race-ready tyre option

     

     

    🧠 Why Use This Tyre on a Sur-Ron or Talaria?

     

    Advantages:

    • Massive front grip in soft terrain (loam, sand, mud)

    • Better rollover in rocks/roots (21” = less deflection)

    • Ideal for aggressive trail, enduro, or MX builds

    • Pairs great with 18" rear wheel and soft-terrain tyre (e.g. Millville II 110/100-18)


    ⚠️ Challenges:

    • Not a plug-and-play on Light Bee or Sting → requires 21” front wheel mod

    • Taller tyre = may require fender lift or fork clearance check

    • Slightly slower steering feel (21” wheels are more stable but less flickable)

    • Not DOT-approved — off-road only

     

     

    🏁 Performance Breakdown (on Sur-Ron/Talaria builds)

     

    Terrain Performance
    Soft Dirt / Loam ⭐⭐⭐⭐⭐ – Incredible grip, digs into ruts
    Mud / Sand ⭐⭐⭐⭐☆ – Clears well, excellent self-cleaning
    Hardpack ⭐⭐⭐☆☆ – Usable, but not as strong
    Street / Pavement ⭐☆☆☆☆ – Not street legal
    Stability at Speed ⭐⭐⭐⭐☆ – Very stable with 21” wheel
    Agility / Steering ⭐⭐⭐☆☆ – Slightly slower turn-in vs 19”

     

     

    🔧 Should You Use It?

     

    Use this tyre if:

    • You have a Sur-Ron Storm Bee or Stark VARG — direct fit, ready to shred

    • You’ve converted your Ultra Bee / Sting / Light Bee to 21” front wheel

    • You want a soft-terrain-focused front setup with max grip and stability

    Avoid if:

    • You’re running stock 19” wheels on Talaria or Light Bee (tyre won’t fit)

    • You need street-legal tyres (this one is NHS – off-road only)

    • You’re prioritising nimbleness over front-end traction

     

     

    💡 Pro Tip: Run a 21” Front with Lower PSI + Matching Soft Terrain Rear for a Killer Off-Road Setup

     

    If you're upgrading to a 21” front wheel on a Sur-Ron Ultra Bee, Storm Bee, or Talaria Sting R, pair the Kenda 80/100-21 Millville II with:

    👉 Rear Tyre: Kenda 110/100-18 or 100/90-18 Millville II
    👉 PSI Setup:

    • Front: 12–13 psi

    • Rear: 12 psi (trail) / 13–14 psi (MX)

    This combo gives you:

    • Max traction in loamy corners and ruts

    • Smoother rollover in rocks and roots

    • Balanced geometry front-to-back for aggressive trail or enduro builds

     

    🛠️ Bonus Tip: If you're installing the 21" front on a Light Bee or Talaria, you'll likely need:

    • A raised front fender (or aftermarket high-mount)

    • Fork clearance check under full compression

    • Possibly shorter travel fork limiters if you're running soft suspension
