Tuning expert Stage6 has added another highlight to their already huge catalogue: Stage6 V-Force 4 Reed Valve by Moto Tassinari Honda CR85 / Derbi.
The V-Force 4 reed valve, originally designed for Honda CR 85, can be mounted on original Derbi Euro 2 / Euro 3 / Euro 4 engines, the crankcase must be slightly milled on both sides of the valve, however.
Compared to the V-Force 3 version, the V-Force 4 offers some all-new features and improvements to dramatically increase the performance of your race bike. The reed valve with double reed tip was developed for racing and optimizes air-fuel flow. Torque, acceleration and overall performance are improved across the entire rev range. The V-Force 3 is already very impressive, the newer V-Force 4 is even more efficient and is clearly built for high-end tuning.
V-Force 4 improvements / new features:
- pre-curved reed petals for improved sealing
- petals: improved carbon fibre technology
- increased flow due to wider reed cage
- petal surface enlarged by 10.5% = increased flow rate
- optimized fuel/air supply due to flow-optimized layout
- longer reed stops = less stress for petals = longer petal life
- more aerodynamic shape for better flow
- less wear and tear due to rubberised petal contact area
Attention: for use with Derbi engines the crankcase has to be milled a bit.
