3.) Rottweiler Intake Kit with 80mm Velocity Stacks.
4.) Rottweiler SAS and Canister Delete kits.
5.) Evotech Frame Sliders, Black Clear Clutch Cover with Orange Pressure Plate.

10.) CRG Lane Splitter bar end mirrors.
11.) Bren Tuning dyno session\tuning through the ECU.
Anyways the newest additions to the above list are the RS22 System and the tuning work that was done at Bren Tuning https://brentuning.com/which is local to me in Upton Mass.
I previously had the Hi Slug AR Single exhaust and experienced a failure with it. I had read a lot of bad reviews on how difficult it was dealing with Richard Austin, the owner of Austin Racing however my experience was completely pleasant and refreshing. Without getting in to to many details I was offered a free replacement on the Exh. or half off of the RS-22 system, I went with the RS-22 system. When trying to make the decision I reached out to many RS22 owners and some had horrific fitment issues others didn't, all of the owners were very accommodating to my info requests. As I said I went ahead and ordered the system, fitment was spot on and the install was super easy. I am very pleased with the Exh, the quality and especially the sound. Yes, it is very loud and I don't run it with any of the Db killers installed, I figure If I'm running an outlandish Exh. I want it to be loud as fuck, and it is. I like it. I have about 300 miles done with this system and have no issues what so ever. Here are a few pics



After watching some 650iB Videos online I heard him mention Bren Tuning, after some research it appears they are well known in the BMW S 1000RR world doing some amazing ECU tuning. I reached out to them to see what they could offer me in terms of dyno tuning. They wanted to get their hands on the 2017 KTM SDR and try to crack the ECU and do the tuning through there. They offered me half off Dyno tuning\ECU tuning if they could keep my bike for a few weeks and use it to create a "Flash Tune" service for 2017 SDR owners, I happily agreed. I do believe that service is currently available from them. 1st I'd like to say that regrettably I never got a completely stock Baseline Dyno run before any parts were added to this bike, just didn't happen which makes these numbers somewhat useless. Secondly Bren Tuning uses a Mustang Dyno which some say reads a bit different\higher than a Dyno Jet Dyno. Yet for me I am happy to know what numbers my bike is laying down, additionally it will serve me well when future upgrades are done, I'll have the bike dyno'd on this Dyno and be able to see what increases the new parts\work has allowed.
Here are the results:
Run#3: Baseline run. Rotti Intake, 80mm velocity stacks, full Ti AR RS22 system, Rotti canister and SAS delete, and Rotti supplied PCV and map=178Hp/96. Bren stated it was running super rich and that the PCV and Map was hurting power.
Run#1: Same as above but with (2) 40mm VS fitted=191Hp/102. Bren stated that the 40 stacks gained a few HP but only at the last few 200 RPM and hurt it to much down low.
Run#2: PCV Removed, 80mm stacks fitted, all tuning done though the ECU=189Hp/105





Here is what the tuner, Chris Robillard posted about the process:
First of all the bike came in with 80mm stacks installed, we baselined the bike as it was setup with PC5, Rotti map, everything else the same. We then uninstalled the PC5 completely letting the bike run on the factory ECU fuel mapping. The bike actually picked up 3whp over the Rotti PC5 map. The Rotti PC5 map was incredibly rich in numerous places (11.0AFR). The stock ECU fueling wasn't terrible either and could be used short term without mapping.
We then tuned the bike direct through the ECU with our own custom mapping. The bike picked up 10WHP and 8WTQ over the rotti map and 8WHP and 6WTQ over the stock map. With extra time on the dyno I'm sure we could have made a few more HP but we were satisfied with these gains. Remember, this is all directly through the factory ECU.
After finalizing mapping for the 80mm stacks, we tried out the 40mm stacks, we found that the 40mm stacks made around 5WHP more in the very upper RPM ranges (10,000RPM and above) but lost a good amount of power and torque throughout the mid range. Overall, for the 5WHP were just not worth the sacrifice of mid range power so we put the bike back to 80mm stacks.
Here is a short Dyno run video.

The tuning that Bren has done has made this already beastly bike into an absolute raging animal, it boarders on insane. Yet, at the same time the throttle response seems more linear, smoother and more controllable. Roll On wheelies were never a problem, now their becoming a problem, the front wheel is always in the air. I'm actually having to change the way I ride this bike because of the power, I'm noticing even in Track Mode, Slip #1 MTC and ABS on that the rear tire moves around a bit more. I'm forced under hard runs to bang through the gears far quicker as the bike just bursts through each gear, I have to react quicker, to ride this quicker, its just a brute.
In closing, I plan on putting some decent miles on the bike before any new upgrades. Next up grades will be having Custom Cams ground for me by Web Cams in collaboration with Bren tuning and have them install and tune for the new cams over the winter. I'm thinking, on thier dyno, with cams and tuning I should get close to 200-205 RWHP, maybe a smidge more.
Thanks for reading.
