In stock form, the forks, featuring a single spring design are under sprung for any rider over 100 pounds. With limited travel, adding a stiffer spring in the right leg only per the stock design was not a viable option.
Race Tech instead offers a High Performance Spring Kit that adds a stiffer spring to the other fork. (The overall spring rate in the forks is the average spring rate between both legs.) This upgrade will make a drastic improvement in handling for most riders.
0.50KG/MM KIT
A dual-rate fork spring for the early KLR650. These springs start with a .40 kg/mm winding and after approximately 20% of the stroke, stiffen up to .60 kg/mm for the remainder of the travel. A very nice improvement over the stock springs which are .40 kg/mm for the entire travel.
