2015 Superduke 1290 with cat delete Remus mid pope, Rottweiler SAS delete and annitori quickshifter. I was cleaning my stock air filter and found both a good deal of grime as well as a whole fly ion my intake butterfly valve...!! I installed the straight forward Rottweiler stage 3 intake in less than one hour, the most difficult part was getting the air filter oiled..takes some practice to properly saturate, especially when you didn’t get the no toil oil with a sprayer..had to hand apply.. Took the bike out after install, and really didn’t notice any difference, that is until I grabbed a serious handful of throttle.. The sound is unreal, but the power difference is downright shocking..! Racing my biddies R1 crossplane yesterday two things were apparent. First, my bike began to rival his in terms of sound, and secondly, he doesn’t have the speed advantage anymore..tested at a 50mph rolling start.. If ridden at normal pace the motor is the same gentle creature as before, but stomp on it and scary, explosive power hits so quick that it’s hard to prepare for. Fueling dongles smoothed out low rpm stuttering making embarrassing stalls nonexistent..well worth the extra money. In summary, I will not need to look any further on ways to improve power output on my bike. Install this and consider it good, anymore power and the bike would be uncontrollable..IMO.
