ELIMINATING THE BUTTERFLY
Ample air flow coupled with complete fuel atomization is an essential requirement in any high performance engine. Modern four stroke engines all utilize a butterfly valve in their throttle bodies. The disturbance in air flow due to the use of a butterfly valve diminishes any engines ability to reach is performance potential. Butterfly valves are positioned in the middle of the incoming air stream, splitting the air into two separate paths, right when the fuel is being injected.
This diminishes the fuels opportunity to be dispersed evenly into the incoming air stream, which reduces fuel atomization and engine performance.
ROTATING GATE VALVE (Patent Pending)
The rotating gate valve governs the actual amount of incoming air directly at all throttle openings, however once fully opened, it becomes the floor of the intake track, rotating completely out of the air stream providing an unobstructed full flowing tunnel. The rotating gate valve creates a single, high speed column of air directed into the incoming fuel stream. Creating a collision path for air and fuel, disperses the fuel atoms evenly throughout the air stream.
Finally a simple and effective way to maximize performance.
UNCONVENTIONAL AIR (Patent Pending)
The second breakthrough in design is the actual shape of the throttle body tunnel. The Genius throttle body is no longer restricted to a typical round hole shape. Extensive testing has proven that reducing the tunnel radius at the beginning of the throttle opening delivers air at higher velocities, translating into improved rider control and an increase in low end torque. This feature yields a stronger low RPM performance, creating the effect of a smaller throttle body at partial throttle.
As the throttle valve rotates, an increasing radius is incorporated into the design, allowing a large throttle body effect to be achieved. Morphing the tunnel into an elongated radius provides the effect of varying throttle body sizes.
After extensive dyno and track testing, Geico Honda switched to the R&D Genius throttle body at round 7 of the 2012 AMA Out Door Nationals. Justin Barcia and Eli Tomac accomplished something that had eluded them all season, they ended the day with a 1st and 2nd over all. This was the first time the Genius throttle body had been in competition, finishing in the top two positions was a remarkable accomplishment for R&D Racing’s new design.
Test riders and MX enthusiasts that have had an opportunity to test the Genius throttle body have said, “IT WORKS AWESOME!”
“Better throttle response along with more control of the power band.” “The throttle and rear tire feel connected, giving a more precise feel to the rider.” -Doug Dubach
Motocross Action, Dirt Bike and Dirt Rider Magazine have all tested the Genius throttle body on various makes and models, (Honda, Yamaha and KTM) and they unanimously agree, “The R&D Genius throttle body is the future of fuel injection.”
All components are machined from solid billet aluminum, and held to precise specifications. All throttle bodies are hand assembled to assure exact fitment of each component. Finally, each throttle body is flow tested and calibrated on R&D’s air flow bench.
