The
all-new VFORCE4 is built upon the solid foundation that has made the VFORCE3
such a success for the last 10 years. While the VFORCE3 has been continually
refined over the years, this is a complete redesign of the entire system.
Moto
Tassanari jokingly say, "The only thing we didn't change is the bolt
pattern." However this is actually quite true. All the components that go
into making a VFORCE reed valve system have been significantly changed since
the VFORCE3.
While the
most obvious change on the all-new VFORCE4 is certainly the full-length reed
stops, let's take a look at some of the other significant changes as well…
·
All-new reed petal resin system, carbon fibre and lay-up
·
Pre-curved reed petal ensures better seal at tip
·
Wider reed cage for maximum airflow
·
Combined reed tip area increased by 10.5% resulting in increased
total air flow
·
Airfoil shape added to cage tip to increase air velocity from
outer ports
·
Long reed stops added to progressively slow petal tip velocity,
for increased petal durability
·
Reduced frontal area of central wing by 15.6% combined with a more
aerodynamic shape
VFORCE4 PRODUCT INFORMATION
01 WHAT IS THE
VFORCE4 REED VALVE SYSTEM?
The Moto Tassinari VFORCE4 reed valve system is a complete replacement for your
existing stock/OEM reed valve that offers many performance advantages.
02 WHAT DOES
THE VFORCE4 DO?
The VFORCE4 aids in performance by eliminating the stock restrictive reed
valve, with a design that is much more efficient and typically offers increased
reed petal life as well.
03 WHAT CAN
I EXPECT AFTER INSTALLING THE VFORCE4 REED VALVE SYSTEM?
Dyno testing shows an immediate horsepower gain of anywhere from 5-10% through
the majority of the powerband. The VFORCE also greatly increases throttle
response and acceleration, while also broadening the peak power.
04 WHAT'S
INVOLVED WITH INSTALLING THE VFORCE4 REED VALVE SYSTEM?
Simply remove the stock reed cage assembly and replace with the VFORCE reed
valve system. The VFORCE is truly a simple bolt-in. If you're able to check
your reeds for wear (which you really should be doing at least annually) then
you have all the skills necessary to install a VFORCE reed valve system.
05 ARE THE
REED PETALS REPLACEABLE? CAN I DO THIS MYSELF?
Yes the reed petals are completely replaceable by the end user. The VFORCE4
reed valve is completely "screw-free". The entire assembly literally
snaps together, making reed petal changes truly a "snap".
06 WHAT'S
INCLUDED WHIN I PURCHASE THE VFORCE4 REED VALVE SYSTEM?
Moto Tassinari product line brochure, Moto Tassinari and VFORCE decals,
detailed installation instructions, VFORCE reed valve system (including reed
petals) and gaskets.
