[@paulcox4774]

It’s a snowy and cold day in Indiana and my Street Bob and I are both under blankets. Thanks for the virtual ride. I needed it!

[@carlito3624]

Paul Cox thanks for the laugh 😂

[@CactusJack252]

Everyone is so gun ho over the new Low Rider S (I really like it), but the Fab Bob just has a super nice complete look. Those meaty tires and headlight just screams badass.

[@jafo4u508]

I prefer the Lowrider S looks, and the front light might take time getting used to.

[@HS-zu9qq]

100% bro ...fat bob is a beast

[@jonnymac8925]

Old post, but the headlight is a love/hate for most people. They either love it or hate it, personally I love it. It's something different and it looks bad ass! I've seen some with the 5 3/4 headlight and some with the 7 inch headlight conversion and it just didn't look right. The closest I've seen was a 5 3/4 with a Sportster headlight eyebrow, but it still didn't look as good as the stock headlight. That's just my opinion!

[@antgarza4031]

And the Softail Slim is cool too haha

[@jamesmac4447]

After my fat bob purchase? I am glad I went with it instead of the used crashed low rider st ! 🤓🤔

[@Firestorm637]

Love the Fat Bob Headlight. I would buy it just because of the headlight. With LED’s, like car headlights, change is in the air. Retro is not the only type of style.

[@jerrypeevey]

I put the 19" windshield on mine and it was the best move I made. 120 mph and it feels like you could drink coffee and use one hand. Not that I would do that, the coffee I mean.

[@TeensierPython]

Jerry P. - I’ve been debating on the windshield size or maybe going with the Memphis shade mini fairing. Good to hear the 19” works. I need something to cut the wind on highway rides.

[@AlexandruVataman]

I tried 115 without windshield lol

[@K9RickRet]

That’s a great bike! Love your explanation of the Stage 3 vs Stage 4! So many dealers just push rides into the Stage #4 because of the price/profit margin! Appreciate the honesty! All the best in 2020 to you, Matt!

[@Burzurk1987]

I just got my 2019 Fat Bob with the TBR exhaust. It’s all blacked out. I have a nice tinted windscreen on it. LED lights/signals front and back. I just take short training rides of about an hour a day. Practice slow maneuvers, uturns, emergency stops, swerving, etc. My bike sounds almost exactly like yours! Amazing torque. My uturns from a stop are still improving, but I need more work! I live in the Phoenix area. Love my FAT BOB 114!!!

[@vivalapete7504]

Have you done a fatbob vs Low Rider S video? That may be a cool one to make. Highlight the differences between them and what type of rider may benefit from one model over the other ✌️

[@happycoffeebot5306]

I know video uploads can never fully capture any sounds precisely, but that sounds pretty perfect to me. Thanks Matt.

[@markschroeder1581]

Matt you did it again! You sold me on the Fat Bob with your review of the 2017 model; I now have a 2014 Fat Bob with Stage 1; but now I must say the Softail version is worth considering - awesome video!!

[@moulis05]

Ive had the Stage 4 on my 2018 breakout for a year now and am more than happy with the way it performs. Drop it down a gear and twist the throttle and it almost leaves u behind. It would be cool to see some content on any road trips or rides you might have planned in the future Matt. Cheers.

[@dennisholloway3329]

I know this comment was 2 years ago. I'm considering moving to a cruiser and I'm kinda torn between a ducati diavel and one of these. What kind of horse power is this thing putting out. Why does it seem to accelerate kinda sluggish? At least the video makes it seem that way. I'm currently on a kawasaki z800 which isn't a rocket ship but it climbs faster than this speedo is showing. I'm at around 116 hp and 98ft pounds. Bike weighs in at 500 pounds so it's not light either

[@ka-bar5060]

The worse part of this entire video is the damn ads from KZbin interrupting the great ride footage. Man, this bike is a BEAST!!!

[@hexhead5732]

That fat bob looks beefy looking and fast sounds great it makes me want to trade in my Yamaha and go Harley

[@K9RickRet]

Just do it!! You won’t be disappointed! 👍

[@franciscvarga1212]

i traded my suzuki gsxr1000 for it , i never look back....sometimes top speed is not everything.

[@mtdman1146]

I started riding a zx6r, then zx7r, and came off a Duke 690 for it. Once thought I would never own a Harley. I do miss the Duke sometimes what an extremely lightweight and torquey bike. . The 114 fat bob is just an awesome bike I love it.no regrets. However i didnt enjoy the stock handlebars for long rides over an hour. 10 inch risers and t bars fixed that. Bars are right at shoulder height it's perfect. Wild 1 Chubby savage risers + bars, two bros comp s 2-1, fuel moto intake, power vision, woods wm8-22x cam, woods lifters + pushrod. The bike absolutely rips, sounds amazing, and with the new bars I can ride the bike all day.

[@carlito3624]

I went from a CBR RR to a fat bob 114 & love every second of it. I never saw myself on a H-D until I saw the new fat bob. Now I’m hooked.

[@Logan-or5qw]

They are great bikes! I can't think of anything to complain about on mine. 5 gallon tank would have been nice. But most of my riding involves 100 miles or less so its not a deal breaker.

[@practicalsigma]

Would this be a good fit for someone 6'3" tall?

[@thedeak]

Love hearing this bike rip through the gears with that awesome exhaust!

[@iancrandall9803]

I love my 18 fat bob, just wish I had bought it at laidlaws and saved myself almost a grand

[@hoss6048]

Always enjoy the ride along Matt. I stopped in last week and talked for a while with Rick at your dealership. Appreciated his input and conversation. I stopped at another dealer and saw that a Sport Glide was marked up to 23000 dollars....I can dig what y’all do with prices..

[@MattLaidlaw]

Thanks man

[@soorajsaikumar]

The most underrated Softail, i wish it came with a 5 gallon tank. This will be my next upgrade 👍🏽

[@carlito3624]

sooraj sai ugh so true I wish we had the 5 gall tank too. It’s just not good enough.

[@jamesmac4447]

Anyone know of a cool tank upgrade for the fat bob ?

[@imtybindare]

I have a 2020 fat bob 114 and just did a stage 4 with the SE heavy breather filter. 2 questions 1) I can't reach the foot brake pedal, do you have the same problem as the filter is in the way???? 2) my top speed is 120, how can I surpass that??? I put the road warrior fairing with 11" windshield from Memphis Shade to give it a killer look. Looking forward to your response....

[@sabirmiah1985]

If I just install that exhaust would the Fat Bob sound like that?

[@christopherbrown5735]

I could listen to this for hours, sounds so good

[@BBD40]

TBR is awesome

[@TeensierPython]

Bought one 8 months ago. Then got a fantastic deal trading it on a Road Glide. Kinda regret it, but only a little. That fat bob is a super cool bike.

[@simongoddard8490]

A friend had a Fatbob with that exact setup dealer fitted from new. All he got when cracking it open was clutch slip and had to spend a bunch more money on clutch upgrade. Unlike the touring model the softail stage 4 kit did not come with updated clutch parts in the kit in the UK.

[@bikeracr]

Stage IV going on my Street Bob soon can't wait. she will be a rocket

[@Itsme-mx5tl]

Does it ever rain there?

[@scott1111]

Does the air-intake and filter make your leg in a weird position for the brake or comfort? Thanks

[@aliencode8681]

I think this bike would look great with mini apes on it can you guys get a pic with one so I can see what it looks like i am having a hard time deciding on what bike I want to get I just have my own style

[@Twilson_Vtwin]

100mph effortlessly, I NEED a m8 Softail in my life

[@petterin1]

True words!

[@carlito3624]

Harrison Wilson you really do!! My Fatbob lives at 100, One handed. Such a sold frame. You won’t be disappointed.

[@flibbertigibbet6200]

What would be the full cost involved for this and how much BHP do you get out of it please.

[@joshchapman2706]

Fat bob vs low rider s ? What handles better in your opinion

[@MattLaidlaw]

They are so close that I couldn’t pick one over another.

[@Apothas541]

Matt Laidlaw what about for commuting? Does the “fairing” on the lrs offer enough protection at the sacrifice of mid controls (leg position) in a factory to factory comparison?

[@motofrodo]

This is exactly what I’ve been looking for for my 18 fat bob. Wow! Need a quote, Matt!

[@TheMakarov9]

Matt, I have a 2021 Fat Bob and want to do the stage 4. Please give me a good estimate of what this entire kit and labor to install costs

[@jjs8046]

@Shaun DuVall any problems with cops with Bassani exhausted?

[@kainalugreig4639]

Shaun DuVall save your self some money i got a 2019 fxbb with a tbr exhaust a power vision and a s&s 475 cam and I have two buddy’s one with a stage 4 fxfb and a stage 4 fxbb and my bike is just as fast as as both and for quarter of the price the fat bob may have a little more on the bottom but top end no problem

[@matty7901]

Matty... what brand/design are the cream gloves you are wearing plz?

[@laurencehiggins239]

What tires are on this bike, they’re AWESOME.

[@tank7358]

Man, great video, as usual. I find it uncomfortable at triple digits on myb'19" roadglide, getting beat up by the wind... cant imagine taking 100% of it, without any fairing. That being said, I like the style of the FBob.

[@outcastedbro]

Love this underrated bike!

[@powerman1972]

What bike do you like better? The this fatbob or the lowrider s from your last video?

How do you ride this thing with the front wheel on the ground?

[@andrewhenley2161]

You just give up on blurring the speedo?

[@mhopkins491]

How much for the stage 4 kit

[@The_dirty_larry]

What are the dyno numbers?

[@TH3G0ODGUY]

117 stage IV kits usually dyno a bit over 120 RWHP on our dyno depending on exhaust and what temperature it is that day. My stage IV 114 kit dynoed at 118 RWHP, or was it 117, cant remember, not that it matters much.

[@Apothas541]

Is it just the view angle? Full acceleration doesn’t look shocking but I know it is

[@amg5795]

Matt Knows how to drive a bike for real! Doing over 100 on a busy hwy with no fairing.

[@1550tc]

Nick was right a few months back, the higher the rear end the better these dynatails handle!

[@Artamon8371]

Any links to all of the parts to this kit? Pretty sure this is my winter project :D

[@Azzow15]

Hi matt. Just curious how many softails and or fat bobs have come in complaining about a foggy speedo. I'm on my third and still have a foggy speedo? How did you stay on that bike at that speed haha. I go over 100kmh and can't hold my head up. Agreed definitely need a windshield.

[@nelsonhood]

Do I understand this correctly? At lower RPM, say 3000 rpm, Stage 4 actually has less torque than Stage 3?

[@omurcada01]

I noticed that the speedo/tach one the fat bob was different than stock, is it a Harley or after market one?

[@MrAndrew1953]

Stage 3 and a fairing would do it for me. Would Z bars work on this bike okay with that power and torque, not make the bars flex?

[@Apothas541]

Has there been any change to the bike from 2018-19-2020? Aside from color. I’m looking at one for my next purchase, and want it in white, unless there were upgrades for the model years

[@Jonathan-L]

That TBR exhaust looks heaps better than the OEM pipes on the Fat Bob.

[@MrMann-gt1eh]

Matt, between this bike and a new Low S, which bike would handle turns at a better lean angle? About the same? Flickability? Traction in a turn...

[@neil4602]

Yeah Matt you’re dead on. I don’t know who the manufacturer is, but I’ve seen a fairing that fits that headlight and it looks badass. Maybe Memphis Shades.

[@danielherz12]

Tarpon1989 Dougz Customs Spartan Fairing. Check it out

[@Mr.Stroke0331]

What’s the total cost for that upgrade “kit”

[@tedd5936]

about 4.500

[@steverollins1467]

What mileage does an M8 stage 4 get vs stock? How long will that tiny tank last. Wish Harley would get their head out of their *** and provide a larger tank option!!!!

[@tetlow2]

I wanna see a new low rider s with a nice set of apes, forward controls and some stage 3 torque. It's a sick bike but I prefer apes to t-bars, but I don't know how it would look with the fairing tho.

[@RevJay_Rides]

Great video, Matt. I just started modifying my bike. I have to do a little at a time. It was completely stock for 9 months. Now, I have very minor additions. Someday, I’d like to change out the exhaust and do some other mods to the engine. Just can’t do it right now. In the meantime, I get to live vicariously through your videos. Haha!

[@Maroun.]

How much did it cost? And plz send specifics status change.

[@corneliusx1811]

Are they ever going to figure out a 5 gallon tank in this bike?

[@My.name.goes.here.]

Still waiting for a Harley that I can drag a knee on in the twisties. If they ever release the Bronx....just maybe, my only real concern is that it’ll be super slow

[@maryloupritchard9038]

Don't knock it till you try it. I've had my 2019 117 FatBob at Horse Thief Mile at Willow Springs. Not as quick to drop into the corner as a street bike, and you have to move your butt over an extra inch or two before the deep twisties, but it's not as bad as you would think, and you can pass everyone at the bottom on the straightaway for sure. :-)

[@yachtclub3774]

If you get this message can you let me know how you like it so far? I never thought in a million years that I would get a Harley but this bike has me thinking...

[@scottbradley3268]

@@yellow-_-toaster5627 if you enjoy the feeling of a bike accelerating so hard it requires hanging on for dear life this bike is a good start. I changed the oil pump, cam set bearings, pushrods, and had a new dyno tune to prevent it from blowing the top end like both my Stage three 2017 and 2019 Streetglide CVOs did.

[@superawsum3]

I want to know and have been told 112 is the most this bike will do stock. I had a stock 2020 114 Fat Bob reading 118. A guy at Harley Davidson said these digital speed odometer can be off up to 4mph. What are your thoughts on getting more top end speed or is it even possible with this M8 engine?

[@ecrusch]

That bike looked and sounded very cool. That's some serious dough to sink into your bike though. And lastly, your local streets blow as bad as our local streets in Orlando.

[@AlekseiTretiakov]

I wanna to buy it, but I don't have a garage. It's not an option to keep it outside, isn't it?

[@MattLaidlaw]

You can keep it out side. Get a cover and wipe it down often or corrosion with eat the aluminum. Be careful of thieves.

[@samuelfernandezbjj]

Is that two brothers exhaust CA legal? Will it void the warranty if it's not, or is that just with an aftermarket tuner? Thanks

[@jerrypeevey]

Just when I get stage 4 out of my head you drag me back. Just got the Dominion bronze collection for my Fat bob in white. Hope it looks good as I imagine, Love the bronze exhaust on the wht. FXFBS at 5:00 min mark / What IS that ?

[@kevinbowers7407]

Why have you removed you last video

[@mikegill9485]

I got a 19 with stage two torque cam and two brothers exhaust as well, color Bonneville salt👍👍

[@Azzow15]

I have owned one of these for 2 years now it has a stage two with torque cam. The worst thing about the bike is the fuel tank size once getting the stage two is only doing less than 200km per tank. Which is a pain on a longer ride. But everything else about this bike i cannot fault. Is quick handled great and corners like a Ferrari. Very comfortable although i did get my original seat custom rebuilt. I love the headlight to matt. Thanks for the video. Oh how do you guys in the states go with the Speedo on the fat bob? I have had mine replaced three times because it leaks. I met a guy the other day with a fat bob his had it two months and already on his second? What's the go with that Matt?

[@mojomanmurph1925]

This bike is fun to ride just stock. I couldn't imagine what it would be like with Stage 2, 3 and especially 4. Totally agree with getting a fairing of some kind because above 70mph, that wind is hitting you right in the chest. Yes, do a video on the extended warranty when going to Stage 1-4. I discussed the issue with several dealerships when I was shopping around for Stage kits. Their overall suggestion is to go with Harley parts with the extended warranty. Wait till you get that bike paid for or many miles on it until you start experimenting with aftermarket parts because it can get stupid expensive if something goes bad.

[@sekoivu]

Cool bike. I like that fat bob and its head lamp. Only thing I would change, are the pegs (I would like mid pegs). Espcially with that Stage 4 kit.

[@jamesmelter5914]

Hey Matt, can you tell me how this compares to a 2017 dyna low rider s? I test rode a new low rider s but didnt really like the feel or sound of the m8. I like the sound and feel of the 110 ci twin cam more still. This video has made me rethink it a bit. Can you compare them a bit?

[@IGOFAR650]

[@azuros54]

Hello, thanks for the great video. May i ask if having a full exhaust system is mandatory wgo Stage IV which will probably be my selection for my fat bob 2021. Here where i live in Quebec laws are very strict concerning sound/pollution.. also i got to admit i love the look of the Vance&Hines hiOutput slip ons.

[@WhiskyJackR]

Great video Matt, loved it! Now I have a thought which may or may not have occurred to you. Lots of people love the Softail chassis. Many don’t want to move up to a full tourer as they don’t want to lose an ounce of agility. How about a special Sport Glide build with a Batwing Fairing and Boombox infotainment system. This would potentially become the entry level tourer that would fill a gap. Perfect for some wanting the agility with a fully featured bike and a stepping stone for others. Just a 💭 thought.
