⚡️ Fitment on Sur-Ron & Talaria
| Bike Model | Stock Front Tyre | Fitment | Notes |
|---|---|---|---|
| Sur-Ron Light Bee X | 70/100-19 | ✅ Direct fit | Same size as stock — bolt-on upgrade |
| Talaria Sting R | 70/100-19 | ✅ Direct fit | Perfect fit for trail and mixed-terrain riders |
| Talaria XXX | 17” front | ❌ Won’t fit | Needs 19” front rim conversion |
| Sur-Ron Ultra Bee | 90/90-19 | ✅ Fits (slightly narrower) | Slight weight saving; more nimble feel |
| Sur-Ron Storm Bee | 80/100-21 | ⚠️ Needs 19” wheel swap | Stock is 21” — this would require conversion |
🧠 Why It Works Well on Sur-Ron & Talaria
✅ Advantages
- Excellent grip across multiple surfaces — perfect for riders who ride everything from hardpack and clay to dry trails and light loam
- Lighter and more nimble than stock Ultra Bee front tyre (90/90-19)
- Michelin’s flexible casing = great bump compliance + traction at low speeds (ideal for e-moto torque delivery)
- Directional tread — reversible for terrain tuning
⚠️ Things to Consider
- It’s not ideal for deep sand or very soft terrain — for that, the Starcross 5 Soft would perform better
- As an NHS tyre, it’s not road legal
