We chose the 2-1 layout (2 wheels up front, 1 in back) over the traditional 1-2 trike configuration for its superior handling, stability, and rollover resistance. We not only wanted the platform to have phenomenal straight line acceleration and braking power, but also have the ability to hug the road in the nastiest of corners.
With the weight biased towards the front of the vehicle in a 2-1 layout, the vehicle inherently understeers. A traditional 1-2 layout tends to oversteer. Oversteer is a very unstable and dangerous condition in a turn where the rear of the vehicle loses traction first and the vehicle can ‘swap ends’ (spin-out). TriRods are tuned for neutral to slight understeer for aggressive but safe cornering.
A vehicle’s ability to resist rolling over is largely dictated by the height of the center of gravity and track width (distance between side by side wheels). Because braking forces can reach greater levels than acceleration forces (3 wheels working in braking and only 1 or 2 wheels working in acceleration), the 2-1 layout has the best rollover resistance of the two designs. With a center of gravity close to the ground and a wide track, TriRods have uncompromising stability and unmatched cornering capability.
