As an avid mountain biker and Road Glide Special owner, I know that aside from losing excess body weight, rotational weight loss (wheels/tires) is we're to "put your money". Nice vid!

I had a Deltran Lithium battery and I was in disbelief on how light it was. 4lbs vs 23lbs. It doesn’t seem like it would make a difference, but it was most noticeable when lifting off the side stand. It made the bike feel not as top heavy.

One way to reduce weight is to go on a diet.....a reduction in the unsprung weight (wheels) means a reduction in rotational inertia...(this DECREASES the amount of energy that goes into accelerating the bike, it also REDUCES the amount of energy required to brake the bike: ie. it will now stop faster), it also means that the bike will be more flickable going into turns...it also means that the bike's suspension will be far more responsible to bumps and dips in the road...meaning the bike will stay on the road better and grip it better.

I recently lost 350 lbs on my bike. I took the back rest off and now the wife won't ride with me.

Doing BST , aluminum swing arm, Lithium battery on my street glide special. Not to mention other mods.

Your right about the weight but these bikes are so heavy to begin with, Imagine a Streetglide with a stiff and rigid cro moly frame fight from the factory. Ive got my Streetglide just under 800lbs by upgrading shocks and exhaust but imagine the bike was lighter from the jump though. I like the bagger because its fun to ride and a hobby to make it better, full on sport bikes you get speeding tickets so its not worth it. Id like to see the baggers lighter with performance in mind. would be better gas millage too which keeps geting worse on these heavy ass things

Rather than spend $4000 on wheels to get 5hp, spend the $4000 on a stage 4 kit and get 50% more horsepower!

Just recently found yall after purchasing my fxdr and looking for mod videos. I like yalls style and format. I'll definitely be bringing mine to yall for some major upgrades

I used to be all about those carbon fiber wheels. I have now removed my set and would be willing to sell them. Last summer a small rock bounced off the highway and hit the front wheel and the wheel exploded at 75mph while we was passing through Ohio. He spent 5 weeks in ICU in a hospital a long way from home. I loved the wheels until then. Other than on a clean drag strip you would have to insane to even consider running carbon fiber rims on the public streets. This video inspired our carbon fiber wheel adventure. For the investment you can accomplish the same hp spending your money on your engine. Please don’t use carbon fiber wheels on the highway. It’s not worth your life. 🚨🚨🚨🚨🚨🚨

Less unsprung weight does not necessarily mean better handling. Better for power . But unsprung weight depends on a number of things in 4 wheel situations adding weight in mist cases is better for handling especially on dirt

I need dat green cush boi!!!

You guys keep speaking my language. I’m on the 2nd warranted rebuild of my stage 4 M8. Once the warranty is out we are going to have a nice long conversation.

Very good video with the explanation on unsprung weight!!

Looking at carbon fiber saddle bags. Never even thought about wheels as well. Thanks for that.

I did the lithium battery. Exhaust is on the list. To shave weight. What I want to know is how to reduce weight from a batwing fairing.

What about the weight you can save from the compensator. Go solid 👍

So has BST fixed the problem where the wheels are breaking after hitting potholes, or shearing off?

Nice video......👍👍👍👍👍 those BST carbon wheels are insane...

Cool stuff though as always well at least sometimes you get what you $$$$ for.

The average rider is usually making payments on a bike and can't justify spending over 4k on a set of wheels thats just insane. Obviously there's people who have deep pockets and don't can't how much they spend. Thats who parts like these wheels are for. Sucks when the average rider can't afford this stuff. And you know the mark up is massive as well.

Spend 3 grand plus just to get rid of 100 pounds... yeah no thanks

I’m pretty sure I’ll be putting the BST CF wheels on my Fat Bob sometime in the next year.

Definitely going the BST route with the H-D Lithium Battery.

Are lithium batteries good?

Can't believe they put a 20 pound battery in a Harley...it's 2019...need to get with the times lol. Harleys are cool but I'm not a fan. Those wheels are pretty cool. Wonder how they old up over time with wear and sunlight.

Ceramic bearings are awesome for super smooth roads only. They do not like impacts at all.

My next project with moonshine HD stage 2 and those rims

Damn if I ever make it down there I’m going to be leaving your dealership poorer then when I came in. Lol

4K for a set! 😬

I like all the stuff shown but I noticed there was no mention of price: can’t imagine a set of carbon wheels are to much less than picking up a 2nd bike, and the fancy batteries gotta set ya back half a mortgage payment or cotton pickin close anyways(yikes)

Carbon rims are still a little too pricey for me. The serious content in your videos is very welcome. Thanks for putting forth the effort.

If you're worried about weight, don't buy a Harley.

Y’all should watch the big bear chopper video about light weight wheels affecting the gyro of the bike ......

fast and easier way is don't by a Harley Davidson. the bike are just way to fat. not a hater of Harley just a realist. I own a 77 triumph and a 73 Yamaha dt400 punched out to 500 flat track bike, as well as the one Harley I have is a WLA flathead don't know the year was a basket case only the motor was kept . it's a race bike as well vintage dirt track racing.

If you can make a battery that small what about one stock size an: have 30Ah to 40Ah storage instead

On the flip side… a heavy bike feels nice on the freeway

Myself I wouldn't run carbon wheels on street, this is y I went PERFORMANCE MACHINE WHEELS, not as light but way stronger for street riding

Rumor has it the camera man also has a just for men beard with a slick back fade.

Weight reduction does not equal horsepower...only more fuel and air can generate horsepower...what lightening the load does it give you a better power to weight ratio.

Great video, What about a radio delete because I never listen to my radio at all, Will that shed some pounds ? I already did a tour pack quick connect on my 2017 Ultra Limited which made the bike handle way better because it was too top heavy, I can take that on and off when I go touring if I ever get time to do that.

Kevin at Big Bear choppers said that these carbon fiber wheels aren't good for Harley Davidson in my opinion they look sick as f

Big heavy bikes needs a big n heavy gyroscope ... the other stuff; agreee with you misters.

Great video guys.

Harley's LIFE battery has terrible reviews. There are much better aftermarket batteries.

just went tot he BST site, now have a serious case of sticker shock. 4.4 grand MINIMUM for a set of wheels for my 2020 RG. I like my chrome look too, is there a way/brand to save weight and cash and stick to metal wheels? just seems a bit pricy dyno wise to spend 4k for a 5-10 TQ numbers. these wheels are amazing but I aint got that kinda bucks for adding bang.

I thought carbon wheels were amazing until I hit a pothole on my bicycle where the wheel fully collapsed and sent me to the hospital. Can't imagine what it would do on my motorcycle. I'll stick with the metals for for now...

Hey guys happy 4th from your friend from the frozen tundra 🇨🇦

Man i worry about people mounting tires on a rim like that. Id be so stressed.

“O” No, in house Fincacial. I am sunk now. Should have stopped at the last video. Definitely need the carbon fiber wheels, can you put Perelli night dragons on them?

Stupid question- is a lithium battery the same as a dry cell? If not, what do You think about dry cells? Thank You. 👍👍

I thought those wheels would save even more over the stock alloys. Did you go with lighter tires as well? I’ve seen in the forums tires are worth a couple pounds each if you get the right set.

Got rims like that for a 98 fatboy??

Wish I lived in TN I’m in Florida

Are these parts universal to some other cruiser rather them be japanese or american? I own a vn800 and I'm trying everythin I can to make it fast and new wheels and a lighter battery I would love!

Shit or Harley could just build a motorcycle correctly. Then it would be light weight from the factory 😂

I own a harley. I am buying a aprilia tuono because the price i have to put in this harley i can get another bike that does what i want. Than i Have two bikes instead of a bike that has a shit load of money into it and not worth that much.

Hello sir. Plz help.me to buy for my bike. My bike is road king special 2020 114. I want upgrade rear and front wheel as carbone. And front should be larger then 19" stock size. And i need right fender for new wheel. Wish i can get right size of wheel. Anyway can i order wheels. And best break system and suspension.. I just watn make best road king in my contury of south korea. No one try carbone on hd roadking and need best break brambo upgrade and shock and suspensions.. Plz help

Price?

Whats the name of that Green thing you're putting in the rea wheel and do you have a link for one that would fit a 2018 Fat Boy? I'm definitely interested in one of those.

Where can I get the supercush? I can’t find one anywhere

Great video/info!

Wow!!!great information 👏👊

Do they have those carbon fiber rims for 2018 heritage soft tail ? If so how much are they?

2 grand per wheel!? Lol damn

They make wheels like this that will fit on an fxdr? Trying to get mine even more lighter

Soo almost 4 grand with tires and battery and you get a gain of 5hp... yeah not with the money

$4K for rims no thanks i'll lose 4 kgs and then spend the $4k on engine mods, double the bank for my buck.

So you really only pulled 29.5#s. Sure there's a performance benefit that's in excess of that for the rotational mass but its not going to make it any lighter to pick up(particularly that low) or tow. Lot of cheddar to loose 12#s in them wheels. Most HD riders could take a 💩 that heavy and loose the weight from higher up. I was hoping for some real practical savings when I saw this video in my search results not some expensive AF wheels and a everyone knows lithium battery swap. Waste of time.

That’s wrong! Reduction of weight does not mean more power. It means the bike doesn’t have to work as hard.

Technology still not there yet for Lithium MC Batteries !

Fat is even in the name of my bike, so it will just be Bob from now on?

Come on what a bunch of bullshit. Only way to make anything 84 lbs lighter is to remove 84lbs. In 30 years of hearing Harley "Dealerships" mechanics ..bullshit. This is definitely the best. Been riding these things for decades there heavy. Uno why because they are built to be heavy

This is bull shit!!! These guys are sales men

That lithium life battery has shitty reviews

Dude on the left needs to clean up his beard at the barber

How much for the battery?

Music is annoying ,

Lose 100 pounds and it’s still 1000 pounds. Lol

+

Harley weight a shit load..how do you just cut that much weight off your rims and your bikes ok?

What does all that shit cost???
