Air filter DNA RACING for original air box on motorcycle BMW R 45N from 1978 to 1985

This is the DNA air filter R-BM6N69-01 for your BMW R Series motorcycles (1969-1979)!

The flow rate of this DNA Fcd filter is high, more than the standard paper filter! This DNA filter features advanced FCd (Full Contour Design) technology from DNA. The installation of the filter is very easy, just follow the information in the Aprilia workshop manual. This DNA filter is designed as a high flow filter for on-road or off-road use.

We all know that an original bike turns a bit too rich for origin for better protection in conditions never reached in our countries (use of engines in very hot countries, bad gasoline low-end and old. ..).

This is why we can afford even with a carburation / injection of origin to opt for a freer air filter. DNA FILTER filters are washable filters that allow more air for better performance with poorer AFR!

This filter R-BM6N69-01 lasts the life of the bike because you just need to clean it and then re-oil it.
