COMING SOON
Under the very familiar body paneling lies a new beast on the 2017 S1000RR. Even though it’s strapped with a large catalytic converter and a restrictive airbox inlet, the 2017 S1000RR makes even more power that its older counterpart.
So what is this spongy mess and why is it on the 2017 S1000RR? To reduce inlet noise.
So this has to be holding back power, right? Well the answer is yes and no.. but mostly yes. As you can see on our in-house dyno testing, power below 9500 RPM goes back and fourth (red line being 100% stock on the 2017 and the green line with the air duct removed on the 2017). After 9500 RPM we start to see a gain in power with the air duct removed. Keep in mind peak power is important but what’s far more important is the gain in mid to upper range RPM. This is mainly where the bike will be raced and where the power is most important. With the duct removed on the 2017, we gained about 4-5whp. Simple mod for decent power! So what’s the blue line? A 100% stock 2015 S1000RR. The 2015-2016 DID NOT come with an air duct to impede the flow of air. Even with this air duct, the 2017 soars above the 2015 (stock for stock).
From what we can see this spongy, black piece is to keep the bike as quiet as possible. The bike seems to be whisper quiet with a little more low to mid-range torque. With it removed the bike definitely has a more menacing intake tone and makes more power up top but also loses torque at the bottom end of the RPM range. This is pretty standard stuff, no surprises there.
We will be updating you with more info as we tear into the new 2017 S1000RR. Be sure to check back!
Just listen to this thing come alive
SATISFIED CLIENTS MAKE US HAPPY
Waiting with interest
This restrictor doesn’t appear to be anything to do with Euro 4. None of our 2017 bikes here in the UK have it installed. Not sure why they are appearing in US bikes??
So after this post we received some feedback from our international customer base, we have been informed that many of their motorcycles do not have the foam piece like we saw on our US model. If any of our international members want to check their bikes, it would definitely be helpful to the community. We figured these would be world wide findings, appears that may not be the case.
Was there ever any consensus about taking this out vs leaving it in?
Yes, take it out
