Stock OEM halogen or incandescent bulbs are typically around 3200 Kelvin, which is a yellow light. High visibility headlight bulbs range from 4000-5000 Kelvin, which is much brighter and whiter, increasing the rider’s ability to see what’s ahead of them as well as increasing visibility of the driver to oncoming traffic.
Shock absorbers are basically oil pumps. A piston is attached to the end of the piston rod and works against hydraulic fluid in the pressure tube. As the suspension travels up and down, the hydraulic fluid is forced through tiny holes, called orifices, inside the piston. However, these orifices let only a small amount of fluid through the piston. This slows down the piston, which in turn slows down spring and suspension movement
