2018 Stage IV Fatboy 117 Cubic Inch with Bassani Road Rage Exhaust 

I appreciate your comment coming from an owner of a 2018 SOftail with this kit. Comment Pinned

Paul Roberts the top speed Change with stage 4?

yes, it sure does, with the big cam the rev limit changes with the tune, it powers to 6500, so with higher revs and alot more power it does go faster and get there heaps faster. If you look through responses to my reply to another comment here you will see the power figures.

my stage 4 sporty was a 40% power increase from standard, and this 117 stage 4 is a 30-40% increase depending on pipes and accesories. its not just 10hp, its a huge difference in power.

Appreciate the M8 and own one (17 Road King) so what I'm about to say is not bias or Harley hate...Crazy fast?!! Dude, you want crazy fast on a big motorcycle try a BMW K1600! It will blow the paint off any street Harley for the same money or less if we compare to a CVO. If you want "crazy fast" an air cooled V-twin with a governor is NOT the way to go. Now, let the hate begin...LOL

James Turner Yeah I don't understand why they hide the speedo. You can't get a ticket from a video on you tube as far as I know. Besides, you can still tell he's doing 90 😂

it's a known issue with stage 3 and 4's .....

Think they had a recall bulletin on that issue.

They do that on purpose so they won't get sued or taken to court,there's no evidence.

He is in LA though so I am sure the authorities would find a way to issue a ticket.

Thanks for sharing that memory Oregon Outback! I can definitely picture that and feel the blast!

Yea, it's bad.

Thank you!

Freedom Rider power vision dyno tune. Much better.

Except it Voids your warranty. Not worth it.

Matt Laidlaw some dealers are flexible on that issue if they do the tuning.

Hey Matt, your implication is that it’s the tuner that voids the warranty and not the exhaust itself. A few months ago I bought a ’17 XL1200C, new, from my local dealer here in Lubbock Texas. Right at the beginning I started talking to them (the service dept,) about putting on a different exhaust and was told that the only thing I could do was put the Screaming Eagle slip-ons or my warranty would be voided. When asked why, they talked about EPA and CARB and other things specific to California. I recently watched your video about Andrew’s ’17 Street Glide and the oil pump issues he had that were fixed under warranty while he was still running his Rinehart slip-ons and how he later, after his stage 4, put the Cobra 2 into 1’s on. And this is all being done in California. This has become a hot topic in all of the Harley forums and Magnuson-Moss gets thrown out there a lot, but there never seems to be a consensus. I’ve even seen where you’ve told people to “consult their local shop.” So far I haven’t done anything to my bike, other than a few cosmetic changes, and I guess I’ll just wait the other year and a half until my warranty is up and then do whatever I want.

Matt Laidlaw Correct. 👍🏻

For sure!

Ernest Reimer What does that tell you?

K shinn I watch the video and am truly unimpressed by the outcome of this build, slow, unstable look at the bar shake. Bike would arguably be faster if you spent half the motor mod money on decent suspension.

they never weill get it LOL

Come on it was easy to see how fast it went.

Tuners can turn off the limiter.

Good call dude, the V&H give sound but dont do much for power. I have the 18 breakout with the 117 stage 4 just like the fatty in the video. I run Freedom Performance Radical Radius on mine, deeper note and much better power. To give you and idea,,,,on a 23 degree celcius day with high humidity it makes 133 hp and 132 torque, on a cool crisp 5 degree morning it makes 140 hp and 139 torque. Like Matt says, the stage 4 milwalkees are seriously fast and the torque is awesome, until you ride one most dont quite get just how brutal they are compared to a stage 2 or 3 kit.

Haha No, Andrew has soemthing else.

I’m not sure but it might help actually.

It’s Bassani

Thank you

There should be a little free play. Yes. If it gets to be too much then you probably need an adjustment. The cable stretches especially when it’s new

Best Harley in a movie EVER! That bike just sold for almost $500,000 recently.

I have vance and hines

N I hav only my dik
