SKXIII, I feel you explained it in great detail. The only thing that I was waiting for and anticipating for you to talk about is the feeling you get what the bike produces while you’re riding it in the 3 different street modes. Whats your thoughts from going from commute mode right to intermediate mode? I personally notice a difference on my own RS660 with a full titanium SC project exhaust CRT-1 that I previously mentioned in your recent videos that it at least feels louder and stronger with exhaust but a considerable difference between commute and intermediate on the throttle response, and I don’t really feel a major lag or dead spot When revving out in intermediate mode. I can only imagine what it’s gonna feel like with a full tune as you’ve mentioned. Waiting on your thoughts. As always great video I appreciate the all the extra work and time you put into every video. Thank you for your commitment.

To me it would seem that a dyno run with a ratio snuffer in the tail pipe would be the best way to insure proper mixture ratio rather than here say on the part of those trying to sell you a leaner running exhaust especially if you feel the running characteristic have so much improved.

I got a good deal on the race ECU from the dealer and am keeping the stock exhaust. It’s basically the same as what you describe but with integrated signals. I don’t ride very aggressively so hoping that keeps the cat from melting. I really think it’s worth it so far.

hey man! nice vid! u mentioned that it would be tough on the bike to race tune it without any aftermarket parts etc. i got my aprilia rs 660 like two weeks ago and im thinking to upmap it to the race tune. do you think it is enough to change the filter to a sportfilter and put on some "better" velocity stacks for the tune not be "damaging" the bike?

Manufacturers tend to run bikes very lean, but think its mostly do to emissions, heavy on either side isnt great, I wouldnt be too concerned with C.C. as much as i would the engine.....optimally you want it running perfect for the motor....if the converter takes a shit you can just throw on full system ($$$) but nothing compared to a motor.....i actually like looks of stock exhaust and it actually does pretty job for what it is.... Prefer a tune with stock exhaust....if you could find mid pipe to delete the CAT and keep stock can but idk if thats possible.... it isnt about the HP but where and how its made....long trip on duke 890 tiday and sure wish i had CC, 😂.

Witch race tune cuz they ha e one for stock exhaust an one for full exhaust?

Wait, so the tune is too rich? I mean if it's been made for the "standard" exhaust then the ratio should be alright. Right? Otherwise why are they providing this potentially dangerous tune?

Going to get mine TODAY from AF1!!!!!!!

Thanks!

Did it mess up your warranty?

Do you cruise around daily on your city streets at 85-95mph? Maybe just for the video? That seems pretty high-paced if someone was randomly going to pull out in front of you not aware or on their cell phone. California is such a nice looking place minus the many gov downsides/pitfalls. Near perfect place to own and ride a motorcycle/e-bike. I do some jobs there a couple times a year but rent a car.

Love your videos except the audio tones you use for the bullet points are way too much bro.

Is there a tune that smooths out the mapping but not really risking CAT damage?

When you say exhaust are you talking a full system or a slip on??

When are you getting an exhaust?

Is the factory warranty still there after this upgrade?

THE RS660 IS DEFINITELY A BEGINNER FRIENDLY BIKE. This is by far tye easiest bike ive ever ridden. Im actually getting bored of it lol.
