1. A two-wheel vehicle suspension linkage comprising:
a suspended body 1, a wheel carrier body 2, a link body 3, a link body 4, a link body 5, and a link body 6 operatively coupled defining a primary instantaneous velocity center (PIVC) at each joint between link bodies;
a wheel operatively connected to the wheel carrier body 2;
a driven cog operatively connected to the wheel;
a driving cog operatively connected to the suspended body 1, the driving cog being disposed transversely inboard of at least a portion of at least one of the link bodies in a plane extending through the driving cog, parallel to gravity, and parallel to an axis of rotation of the driving cog;
an idler operatively connected by an elongated flexible member to the wheel carrier body 2, the link body 3, the link body 4, the link body 5 or the link body 6, wherein the idler is rotatable about an idler rotation axis and wherein the idler is pivotally connected to the suspended body;
the elongated flexible member is disposed along a route between the driving cog and the driven cog, wherein the idler is disposed in the route between the driving cog and the driven cog; and
a damper unit configured to resist movement between two or more of the suspended body 1, wheel carrier body 2, link body 3, link body 4, link body 5, or link body 6.
