I wasn’t happy with the Rally Raid modification of the air filter. The Rally Raid mod on a standard ktm 690 works perfect. But there are some problems with the OEM rally tanks installed. The Rally Raid modified air filter pushes heavily against the front tanks, when riding the bike they will tear apart after some time.
So I decided to buy the Rottweiler Performance intake kit. The kit is perfect to work with the OEM front tanks. Only very very minor rubbing against the side of the seat. It also looks very clean.
