TBparts HD clutch kit for the Kawasaki KLX140. This kit was designed to hold more power from the ground up! #1 we did away with the OEM “jitter” Plate. This firms the clutch up and gives you more grab! Next we upgraded the OEM cork and rubber fibers to Kevlar for improved grabbing power. To go with that we dimpled steel plates for additional friction. Finally the springs, they are 15% heavier than factory, enough to hold big power with the other upgrades, but not too stiff where it makes the clutch pull harsh. All that for $36.99!
