PRO kit is designed with an air cartridge and a spring in both right and left stanchions. Both are installed in serial (spring below and cartridge up).

Cartridge pressure is set up with a hand pump which has a quality pressure gauge. Set up values are included in user and installation manual, and it depends basically on rider’s weight and riding preferences.

PRO kit is totally progressive and it is designed to absorb quite well at beginning of fork travel, and progressively getting stiffer to perform with high bottoming resistance.

PRO kit is only option in categories:

      – Trail
      – On-road
      – Motocross Classics
      – On-road Classics speed racing

In Trial Classics range there are options PRO, EXPERT, EXPERT mk2 and CLUBMAN.

(Only Trial Classics)

EXPERT has an air cartridge and a spring in right stanchions. Both are installed in serial (spring below and cartridge up).

Left stanchion is equipped with two springs in serial with an intermediate spacer in between. Upper cap has possibility of mechanical pre-load. We call this system DMR (Doble Muelle Regulable). Depending on how spacer between springs is installed (one way or another), we will modify the point from which the suspension gets stiffer. It will provide bigger or smaller fork travel being smooth, according to rider’s weight and riding preferences.

Same as in PRO, pressure in cartridge is set up with a manual pump equipped with a quality pressure gauge.

EXPERT kit is progressive (due to right leg) and it is smooth at the beginning and it is getting stiffer progressively controlling very well not bottoming.

EXPERT kit is option only for Trial Classics.

EXPERT mk2 kit is composed in both stanchions by the following components: 3 springs and 2 spacers each side. Respose is progressive in 3 stages, being very similar to the ideal one that is achieved with the air cartridge. With EXPERT mk2 kit, it is not required a pressurization pump.

Upper has mechanical preload capability by means of a threaded screw, 2 nuts and a special washer. This system is called TMR (comes from spanish meaning of Triple Settable Spring). It is available additional spacers to fine-tune the point when the response becomed harder, according to rider´s preference. 

EXPERT mk2 kit has a soft response at the beginning, that is getting harder in a progressive manner, allowing a very good control of bottoming resistance.

EXPERT mk2 kit is available only for Classic Trial motorbikes.

CLUBMAN kit is equipped with two springs in serial with an intermediate spacer in between in both stanchions. Upper cap has possibility of mechanical pre-load We call this system DMR (Doble Muelle Regulable). Depending on how spacer between springs is installed (one way or another), we will modify the point from which the suspension gets stiffer. It will provide bigger or smaller fork travel being smooth, according to rider’s weight and riding preferences.

CLUBMAN kit is option only for Trial Classics.
