Overview

MWR Air Filters are built upon 2 decades of experience in developing and producing high performance air filters for road, race, and off road use.
This experience has been gained working with some of the biggest air filter companies in Europe in areas such as World MX, Dakar (bikes, cars and trucks), Moto GP, WSB, BSB, AMA and even Rallycross. The knowledge gained during this period was invaluable and led MWR to develop their range of performance foam filters.
Using the lessons learned from their WSBK filters, MWR has released a new filter design for your Bavarian Beast! this new filter uses two layers of foam with an ingenious system between them to ensure equal airflow across the four cylinders. Installation is very simple - just place the filter into the cassette with the printed MWR logo to the front of the bike
The Full Race (RACE ONLY) air filter (MC-030-NSF250R)
Filter has a “HE” construction for more top-speed and exclusive high flow filterfoam
FOR RACE USE ONLY
No modifications needed , filter installation with original airbox cover
Developed on the track, NOT on a dyno but in real life on bikes with Data-loggers being tested and developed in part with TOP Teams for ultimate performance. With new materials and a new design, protection is on the same level as the filters above, only for a shorter period of time before they must be serviced. It makes the bike stronger and smoother, therefore it saves tires and fuel. Check the air filter every race weekend and always start each race weekend with a well oiled filter. This air filter is not developed to reduce the inlet noise. Due to the design features of this filter we do not recommend it for road use.
The foam material of our racingfilters have a much more open structure compared to the roadfilters foam material which makes the duration of the maintenance much shorter , the protection is at the same level as our roadbike filters but for a shorter time , therefore the maintenance is much more intensive. Maintenance frequency for racebike filters are after every two race weekends. Therefore are racebike filters are NOT suiteable for roadbikes
Our roadbike filters have a recommended maintenance frequency of once a year …. regardless the mileage . Even when you have ridden 50 miles that year stick to the guidelines , priority for the filter is that the foam must not dry out , keep it “wet” from oil
In countries around the Equator with high temperature and high humidity , the frequency must shortened to twice a year . Racebike filter can stay with the normal frequency of maintenance
Only MWR Biodegradable filteroil and Biodegradable filters cleaner may be used to protect the filter also from backfire.
