ARI FORK OIL SEAL KITS Correct performance from the front fork is a vital requirement for everything from Superbikes to Trial bikes. Ariete has worked hard to produce a special rubber compound which tolerates the chemical additives used in fork oil. We have also refined the design of the OIL SEAL LIPS; which have a ground finish. They offer complete control of the varying internal pressure as the fork is alternately extended and compressed; with no loss of lubricant. We offer over 140 ARI dimensions; which fit more than 35;000 motorcycle models; covering the period from the 1960s until the present day. Each kit comprises 2 oil seals; and comes complete with a sachet of special Arisil grease. This has been specially developed for lubricating reciprocating metal-rubber contact areas. Reducing friction at the point of contact; and increasing the life expectation of the components involved. ARISIL has been designed in the laboratory to reduce the friction between metal and rubber components.
