Losing Front-End Confidence as Conditions Change?
Mixed terrain exposes weak tyres fast. One lap it’s loamy, the next it’s hardpack, and suddenly your front end feels vague, unpredictable, and unstable when you need precision most.
The Front Tyre Built for Changing Conditions
The Michelin Starcross 5 Medium 70/100-19 Front Tyre is engineered to perform across soft, intermediate, and harder terrain. Its adaptive tread pattern and lightweight casing deliver consistent grip, precise steering, and reliable braking, even as track conditions evolve.
Your Simple Path to Control and Precision
Fit the Starcross 5 Medium to your 19” front wheel.
Attack corners with confidence thanks to improved stability and feedback.
Ride faster and smoother knowing your front tyre adapts as the track changes.
What Happens If You Don’t Upgrade
Stick with a terrain-specific tyre and you’ll lose grip when conditions shift, fight instability under braking, and struggle to maintain lap consistency.
What Happens When You Do
With the Starcross 5 Medium, you gain predictable handling, sharper turn-in, and consistent traction across a wide range of surfaces, letting you focus on speed, not survival.
Take Control of Every Lap
Equip your bike with the Michelin Starcross 5 Medium 70/100-19 Front Tyre and experience race-proven performance built for real-world motocross conditions.

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
