Review on Tubeless Tire Valve Stems for Bonneville Daytona 600 Monster 821 - Front and Rear by Matt Crawford
Not suitable for Aprilia (Tuono) wheels
The included O-ring, if you want to call it that, increases the diameter so the valve stem bore in the wheel should be closer to 11mm. This means it will not fit Aprilia 8.3mm wheels. The design seems good, but they don't fit 8.3mm wheels.
Pros
- Suitable for other motorcycles in the product description.
Cons
- Blank
