The kashima treatment of the forks combined with the rainbow treatment of the stanchions dramatically reduces friction. The result for the rider is an increase in comfort, feel and sensation, and greatly improves the performance of your FACTORY fork.  Rainbow Stanchions In order to offer you the best on the market, bos suspension uses the rainbow stanchion treatment exclusively for the factory range. This treatment improves the wear resistance of your fork stanchions, and it also considerably extends their life. The Rainbow treatment dramatically reduces parasitic friction. Combined with the Kashima® treatment of the forks, the result for the rider is amazing! Thanks to the combination of all these technologies, discover new sensations, those of the FACTORY pilots.  Stanchion diameter 49 mm The stanchions have been specially designed to equip the factory range. The choice of the 49 diameter stanchion was an obvious one. They provide the right balance between strength, rigidity and weight. The factory fork offers the perfect mix between increased sensitivity, greater steering precision and the ability to go faster, take tighter turns and still maintain control.  OAS aluminium anodized axle bracket At Bos Suspension, we have chosen to offer you the best of the FACTORY range. For this reason, our fork legs are machined in OAS anodized aluminum and not molded. They receive an anodization treatment that gives them a better resistance to wear, corrosion and heat. The specific characteristics of OAS aluminum naturally absorb micro vibrations. It is thanks to the combination of all these details that we can offer you a fork with unequalled performance.  Coil spring cartridge Our FACTORY fork uses a coil spring cartridge. This deliberate choice offers several advantages such as a linear stiffness curve over the entire travel as opposed to air spring technology. We also chose this spring cartridge for the reliability it provides.  Hydraulic Compression Stop Progressive hydraulic compression stop specially studied and developed by our research department to meet the specificities of the practice of high level motorcycle. This hydraulic compression stop plays an essential role in the operation of your fork. It allows a precise control of the last centimeters of travel of your FACTORY fork. This way, you can keep your equipment running at its best in any situation and focus 100% on the essential: riding!  Tailor made At Bos Supension, you don't just buy a fork. You are unique and so is the way you ride your bike. That's why we take into consideration all the elements to make sure your FACTORY fork works optimally. No parameter is neglected, your weight, your range of use, your level of riding are taken into consideration. It is after the analysis of all these elements that your fork will be adjusted and delivered with a spring adapted to your use.  AMX1 & AMX3 Oils Each product has its specificities. That's why we recommend the use of AMX 1 & AMX 3 oil, designed to preserve the proper functioning of your FACTORY fork and shock absorber and avoid premature wear. These oils will also reduce friction and parasitic noise, while guaranteeing a homogeneous feel and good operation even when the temperature rises. These specific oils have been tested worldwide on all the main competitions and are the result of the experience accumulated by Bos Suspension for more than 20 years now. |
