The VForce reed blocks by MotoTassinari provide more engine power. Specially designed, the VForce reed valve system has twice the reed surface area of a conventional reed block, which is why the reed petals need to move half the distance only: causing efficiency and more power with less wear! The screw free type design allows super quick reed petal replacement and prevents damage because of loosened screws.
This VForce4 reed block is suitable for Derbi EBE, EBS, D50B0 and Honda Motocross CR80, CR85.
With the VForce4 reed block, a new era of this super talent is now introduced. The VForce4 series is not only an update, but a complete re-design of the entire reed valve system. Of course, all the advantages of the VForce3 are completely adopted. However, the design has been improved to make the reed block even more effective. For example, the reed petals are now pre-shaped and made of a completely new resin-carbon fibre laminate.
