We found the solution to all dust problems in Australia. Unifilter Australia gave us an air filter to test that fully met our expectations. The Touratech Research & Development team used the Unifilter in all the races in thelast season and since then have found no dust residue in the air filter box. Another advantage of the filter、 made of high-tech foam、 is the long service life. The filter is not thrown awaywhen its dirty but rinsed out、 lubricated again and used time and time again.
