Product Description: As you all know The Guys at MWR are always on the hunt for power and to keep the Factory and Race teams happy .They have discovered that on the "big 1000cc bikes" the OE filter surface was too small. It doesn't matter what filter you install, you always have a kind of restriction. The MWR "R" filter has been giving the best power overall compared with all other sportsfilters.With the corporation of KHI , MV Agusta and MotoGP teams they developed a new style airfilter that increases the filter surface enormously.On the BMW S1000RR the Surface area is increased by 50%, on the GSXR 1000, 1199, & R1 the increase is 90-100% !!!More & bigger surface means less restriction and better protection. The secret in the new style filters is that they use two different kinds of foam materials. The part where the logo is printed is foam material used for our roadbikes, the rest is the foam material for the full racefilters, placed to create the same effect as the splitterplate on the "HE" & "R" filters. For now four models are available : BMW S1000RR / Panigale 899-1199 / Suzuki GSXR 1000 (09-14) / Yamaha R1 (09-14). Tests up to now show average gains of a minimum 6.5HP over the MWR "R" filters. Unfortunately no Dyno charts are available yet(teams don’t want to share their data with us, so please share yours with us!)The filters are currently in use by : Tom Sykes ( 2 years now), 2014 World Champions Yamaha GMT 94, MV Agusta World Superbike, Ryuichi Kiyonari (BSB), IOM TT Winner Micheal Dunlop, AMA Superbike team TPL Corse ( Ducati), Double 899 Cup Champions (BSB) Carl Cox/P&H Motorcycles and Dani Rivas ( CEV Superbikes, BMW) and BMW Motorrad Italia with Sylvain Barrier.
