阻尼杆叉因过于苛刻而容易触底而臭名昭著。这就是阻尼杆固定孔叉的特性。在过去，改进这些叉所能做的就是改变弹簧刚度、油粘度或阻尼孔尺寸，直到现在。药筒模拟器使阻尼杆式叉的性能与调谐好的药筒叉相似。这些可调阀位于阻尼杆的顶部，并由主弹簧固定到位。这使得它们既易于安装，又可根据所有条件和骑手偏好进行完全调整。赛道测试持续产生的单圈时间比单圈快1秒或更多，而巡航者和金翼车主则对增加的控制和骑行质量赞不绝口。
Damping rod forks are notorious for being both too harsh yet too easy to bottom. This is the nature of damping rod fixed orifice forks. In the past all that could be done to improve these forks was change spring rate, oil viscosity or damping hole size, until now. Cartridge Emulators make damping rod style forks perform like well-tuned cartridge forks. These tunable valves sit on top of the damping rods and are held in place by the main springs. This makes them both simple to install and completely tunable for all conditions and rider preferences. Track tests have consistently produce lap times that are 1 or more seconds a lap faster while Cruisers and Gold Wing owners rave at the increased control and ride quality.
