hlins Racing AB - The Story It was the 1970s, a young man named Kenth hlin spent most of his spare time pursuing his favourite sport: motocross.

Being a careful observer, Kenths attention was continously drawn to one specific detail - motocross bikes had more engine power than their suspension could handle. It was not long before Kenth realised that better performance could be achieved by improved wheel suspension.

hlins Racing was established in 1976, and just two years later the company won its first World Championship title. Despite being in the business for almost 40 years, the search for perfection and new functions is still the main focus of the company.

1 HOW IT WORKS To get your suspension set up correctly

the front fork and shock absorber must be in balance. To achieve this, both must be considered when setting up the new product.

To set up the fork there is two systems to consider.

Spring The main purpose of the spring is to support the rider and bike and restore the set ride height after impact.

Please consult your original fork manual for advice on how to set up your forks spring.

Hydraulic damping The damping controls the forks movement in compression and in rebound by converting the kinetic energy in to heat. The amount of damping is controlled by regulating the oil flow.

3 ADJUSTERS Compression damping controls the energy absorption when the front fork is being compressed, thus controls how easily the front fork compresses when you hit a bump. Rebound damping controls the energy absorption when the front fork is being extended and controls how fast the front fork returns to its normal position after being compressed.

To set the adjusters The adjusters have a normal right hand thread. Turn the adjuster clockwise to fully closed position. Then, turn counter clockwise to open, and count the clicks until you reach the recommended number of clicks.

Cautione! Turn gently not to damage delicate sealing surfaces. Tighten with your hand only.

Compression damping adjuster

1. Adjust low speed To adjust, turn the blue coloured adjuster on the top of the TTX cartridge. Turn clockwise to increase damping, turn counter clockwise to decrease.

2. Adjust high speed To adjust, turn the black coloured adjuster on the top of the TTX cartridge. Turn clockwise to increase damping, turn counter clockwise to decrease.
