Moto Tassinari Reed Valves

Moto Tassinari designs and manufactures the VForce reed valve system, a bolt-in upgrade for two-stroke dirt bikes, ATVs, karts, and snowmobiles. Riders choose VForce reeds to sharpen throttle response and broaden the powerband across the rev range.

The VForce design uses a dual-stage cage with twice the reed-tip surface of a conventional reed valve, so the petals open only half the distance to flow the same air. That layout improves response and reliability, which is why VForce has become a trusted name in two-stroke performance worldwide.

Frequently asked questions

Will a VForce reed valve fit my two-stroke? VForce cages are model specific, so match the kit to your exact make, model and year. Fitment for dirt bike, ATV and snowmobile applications is listed on each product page.

How often should reed petals be replaced? Inspect the petals every few rides and plan on replacing them about once a season on a hard ridden motocross bike, or sooner if you see chips, cracks or gaps at the cage.

Do you offer free shipping in Canada? Yes, on orders over $279.99.
