STAGE6 the V-Force 4 lamellar package, originally designed for Honda CR 85, but which can be mounted on original engines DERBI Euro2 / Euro3 / Euro4, after some processing to the crankcases for correct assembly.

Compared to the V-Force 3 version, V-Force 4 offers some new features and improvements to greatly increase the performance of your bike.

V-Force 4 Enhancements/New Features:

Renewed lamellae in resin and carbon fiber
Curved slats to ensure better seal in the terminal part
Wider valve body to maximize airflow
Lamella contact surface increased by 10.5% which generates an overall increase in airflow
Shaped lamellar package cusp to improve airflow from external holes
Long slats added to progressively slow down the speed of the edge of the lamella, to improve its durability
Central ala front area reduced by 15.6% combined with more aerodynamic design

Less wear thanks to the contact area of the wheeled petals

Attention:remember that for use in the main DERBI it is necessary to slightly mill the base.
