- Master Technician Jamie Myers of Laidlaw's Harley-Davidson recently built up a 2018 Harley-Davidson Roadster for his personal use. He outfitted his bike with a 1275cc engine build with parts from Hammer Performance. Jamie takes us around this build and gives us the details. Then rips it around town.

This was all the confirmation I needed to do the Hammer upgrade.
They stock a sweet air filter cover and everything!
Finally, a guy thats not afraid to use the right hand.
I use my right hand nearly every morning. 😉
Best looking Sportster ever? Love the black and blue. Sounds great! You can see (and hear) the extra giddy up upon acceleration. Love it.
I love the hammer kit, i changed my 883 superlow to the 1275 hammer kit. Man what an improvement. It's a beast now. Nice bike!
This build inspired me to buy a 2017 Roadster and, after 50 years of riding, I love this motorcycle. Modifications included a 4.5 gal. XL1200C tank/seat, Cobra pipe, Euro fender-mounted license plate, factory 48 rear fender and handlebars. Will probably go with the Hammer 570 drop-in cams. Can't wait for summer.
Miles, did you have to change anything for the bars?
This is one of the most beautiful sportsters' I've ever seen. Tastefully done.
30 years of sport bikes & I bought my first Harley 1200 sportster. Love the low end torque but needs a lot of tweaking. Love that bike!
Congrats. I pick up mine next week, can’t wait.
That bike is so nice, massive increase in HP, what a blast, well done Jamie (& Matt) 👍👍😎
That Sporty Roadster is RIGHTEOUS, like Sunday Morning Service, Amen!
Inspirational, I have an iron 1200 that I’m considered doing the hammer kit to.
Dont consider it just do it. Best performance youll ever obtain from a Sportster thats streetable.
Can somebody post the link to the kit for a 07 sportster nightster thank you much love fam💯💯
Same here. Does the ride get smoother on the freeway. Right now I’m at at stock and I can get it to 70-75 with some vibration. Not terrible. I want to increase speed and power but what can be done to make the ride a little bit more smooth?
@@expendable4h002 i did a belt to chain conversion on my 07, 51 tooth rear gave me a little more top end and much more comfortable around 70~75 but yeah you can experiment/research with different size front and rear sprocket to see what's comfortable and it wont break the bank
@@leelizardwilcox6271 last time I checked the DMV doesn't Dyno your bike once you buy it you can turn it into a damn spaceship how are they going to know...
This is excellent! I bought a Roadster a year ago and have wanted to do something just like this. Perfect!
Thanks for posting!
Thanks for watching !
Sexiest Harley I've seen. I was on the fence about getting a Sportster until I saw this one
Can't wait to get mine installed next winter. Have a 2000 883 Hugger with an S&S 1250. Going with the Hammer Performance 1275 120+hp package but with a different exhaust and possibly a Mikuni carb. Gonna run me around $5,000 without installation but by the time I'm done converting it to a balls to the wall bobber it'll be well worth it
Total badass bike, the sound, performance ,and looks!
I am in the process of putting the Hammer 1275,600 cams and head work on my 96 S1 Buell. I have been doing track days and the stock heads failed and also got a piston. Enjoyed your video and everything I see coming out of Laidlaw is great I live in Tampa and we have lost are family dealerships such as Jims and Fletchers
Dude! The HAMMER KIT TO THE ROADSTER, IS THE WAY TO GO! 👍 AMAZING.
Nice build, Jamie! I love it when dealer wrenches run outlaw bikes!!!
A true Sportster used the way it has to be used , nice bike Matt!!
As usual another nice build coming out of your dealership. Sportsters are all about having fun! I have a blast on my Dyna BUT... my Sportster is a very important part in my stable with its rich history. after all these years I find it a must to own one, in fact I am looking to get another to build up. I would love to see some more hot rod Sportster performance builds coming out of Laidlaw Harley-Davidson.
Michael Gurgone That’s what needs to happen!
I don’t know why Harley slept on the sportster for so long.
Give it a six speed transmission and brembos and punch out the 1200 to something bigger.
I always thought they could have done so much more with that line and they aren’t exactly cheap. Look at how fast and what some euro or Japanese bikes come with in the 10-12k price range. I mean you can get on a track purpose 600cc bike that’s decked out with the latest tech and amazing suspension.
I don’t know why Harley doesn’t offer Olin’s shocks and brembos etc. Along with some more CCs.
There’s just a lot of things they don’t do.
Joseph Andreuccetti I agree and why I love my XR1200 sportster. It’s a rowdy bike and what converted me to Harley Davidson.
Fantastic bike and built,the best roadster I’ve seen. Looks really fast, ride safe
I've just seen my idea of the perfect HD Sporster Roadster. From the color to the hop-ups to the powder coating and the exhaust. Simply perfection, or badass, if you prefer. Nicely done.
Its currently for sale at Laidlaws
@@ronhernandez9198 is it still for sale?
That's a sweet looking roadster! And don't worry Jamie, your old heritage is in good hands! 😎🤘
Haha. I love it!
@@MattLaidlaw whut about a 5 gallon tank, too rich?
Lol pimpin
Glad to see you're taking it super easy on the break-in …… :)) Absolutely awesome sounding bike. Thanks for sharing with us.
It’s already broken in. He has owned it for a little while.
Dig the sound. And, it does look fast too. Bad ass, brother. 👍
That kit is just insane
I guess if you’re going to buy a Roadster, then you did it up right! I feel like others on here though, your Softail was straight bad ass. At the end of the day, you work at Harley-Davidson and have some latitude to experiment and play around, especially since you’re a Tech. Well done!
That thing'll turn a lot of heads & maybe convert a couple Harley-haters along the way! Great build Jamie! What a blast
👍🏻👍🏻
I just bought a 2019 XL1200X forty-eight, i'm a lighter guy @ 145lbs, and the bike is bone stock, it has some pep to it- but this thing is a beast!!! I definitely need to open mine up!
Thanks to this video I finally found a windscreen I like for the roadster. Just put a mowhawk on mine and love it.
Ah! There IS a name for it! I got a motorcycle addiction too! Recently added a Ducati Superbike to my stable! Love it!!🍺
Haha. Nice.
No short shifting... awesome... Great use of the throttle... perfect 👌!!!!.... I really enjoyed watching this... haha 😄 🤣!! OK 👌..... thanks for keeping it Real...!!!!
love the way the engine rev's so fast........unlike a stock Sportster
Biker Brian I had a 1200 and it revved up pretty quick. It wasn’t as fast as this bike but 0-110 was pretty quick. I miss that bike.
Dude that is one sick sporty! I love it. I bought a Buell recently and it has reinvigorated me on Harley V-twins.
If I wasn't 6'5" I'd have me a sporty! Maybe a stretched hardtail would work with a 1275 Hammer kit. Sweet bike man, hell yeah
I'm 6'4" and I fit decently comfortable on my 883, mid controls
Cool bike - looks and sounds strong and healthy
The Roadster seems to be great..It creates the vibe to get one..
0:08 something fell a
Out of you pocket xD , sorry, I just found that part a little bit funny. Awesome video and awesome bike!
Great vid and awesome sporty. Wish you would have talked more about the Hammer kit. Pistons, cam, heads, etc.
All you need now is a steering stabilizer and chain conversion kit. Those 2 change the bike considerably. Awesome video
Available thru Storz Performance...
Only three words come to my mind BAD ASS SPORTY
Matt did Jamie ever throw this on a dyno? I’m curious to know what numbers he got.
Thanks Matt. Excellent informative video. You talk sense without hype or b...t!
Thanks !
Looks like a very fun sporty! I'll keep this build in mind.
Always wanted the hammer 1275
* Literally upgrades every single thing on this bike
- " I didn't do too much to it, oh and I powder coated the stock bars"
Yeah, I definitely caught that, too. Pretty funny.
Bad ass sportster. Hoping to do the same engine work on a future project. 👍
That thing sounds filthy ! Love it !
That Sporty SOUNDS and LOOKS like it would give Lesser Big Twins and all Adversaries the BAD End of the Business Stick! ⚡💪🏾
Sweet sounding exhaust!
That is one fine looking bike!!!!
Very nice indeed.
I've always loved Sporties.
I did just the 1275 jugs and pistons on my 883 and it turned her into a beast.
how much?
@@Sam-w9desunder 1k for jugs, pistons, ring installation, gaskets and clutch (I already had a tuner). That is about the cheapest possible. Start adding in cams, head work, etc. And it can get into the thousands fast. I also did my own install. If a shop is doing it, that id pricey too.
@@TheBeardofDOOM thanks
Very tight. Love that lope.
Love the looks and the colour
What a great Sportster!
i was expecting some other video like that stage 4 48 video that you did sir! and am glad i found this video of a fast sportster as well, and happy that you uploaded this video too! expecting videos like this made on a 1200 custom as well, don't we all want to see a fast cruising sportster? :)
parts cost? been loving my 2005 roadster for about 13 years now. when I saw the 2016 come out I figured Harley really hit the mark but the performance upgrades are what really makes this bike sweeet.
Bout 3 grand and some change. Probably end up closer to 4 with a power commander. Hammer kits are pretty sweet if you want to hit 100+HP for a decent price. Even better if you can do the work yourself.
Great build looks and sounds great
Sounds so good man
I come from a modified sports bike background (30 years riding) and yours is the first Harley I've seen that is close to what I'd like .
It clearly pulls strong with great power and torque but can I ask how the handling (ohlins) and brakes compare with stock sportster.
I currently run a supercharged busa and I'm intrigued by a sleeper sportster.
Great build Sir
Awesome video, and Fun bike. Thanks Matt!
I spilled bike respond very well to the throttle thanks for the video Matt take care guys
Bet that thing is a blast to ride!
The Roadster needs and I stress needs rear sets. I was very disappointed with the peg position when I rode one when they first came out. Then I sat on one with RSD rear sets that required RSD exhaust and was amazed with the riding position. The cost, not so much.
HD makes rear-sets for this bike as well. Might be a better choice if you don’t want to change exhaust.
@@MattLaidlaw , they didnt back then. I wish i could choose a modle with rear sets, instead of having to replace what doesnt work for me. Most Cafe bikes have rear sets.
Damn get some!.. Sweet Sporty I dig the colors and the speed...
Front pocket empty when you returned! I saw it coming !
This is amazing, nice set up!
Nice build brother.
Forth. No kidding, that was one badass Heritage.
Sounds and looks awesome!
Gave me some good ideas for my Roadster. Thank you
Awesome build, glad to see you're enjoying the transition. I have to come down and see how I fit on one (6'4"), but the power is impressive.
At 6’4’’ you won’t fit very well and there not a whole lot you can do to make that better.
@@MattLaidlaw Even my Fat Boy feels too low at times, guess I'll stick to a Low Rider build next 😂I gotta come visit you guys sometime
Nice bike what size rear tire
The sportster is famous ones more, freaking awesome.
So this was the 120HP + kit, how is it running now? can we get an update?
I have had some fast bikes, when I watch these, I always wonder how fast though, any dragstrip times? How much HP? Nice clean build, looks like fun
I've run 11.20's on my 120 hp Iron 883 at sea level. Chassis 100% stock, weighs 525 lbs with a bit of fuel.
Been looking at this damn 1275 kit for awhile now. Hard to keep from adding all them hammer performance goodies to my cart. And now time has passed and 21,000 miles have gone by on my "48".....not sure about the kit with high mileage. Probably would destroy the bottom end before another 5,000 miles went by. Nice build bro! Sounds like nice clean power!
That’s still low mileage for a sportster.
He said haven't done too much.. ha. Awesome bike, dream bike
gotta love those tank lifts without taking the plastic off and rerouting wires lol
That is one of the coolest bikes I've seen on this channel. Those shocks are yummy, and that windshield looks great!!
Compared to my 2015 Limited, I thought my 2013 Sportster 72 was fast AF. Now, I’m intrigued with this kit! Thanks Matt!!
Thanks for watching. 🤙🏻
Badass bike bro!😎
love this bike looks great sounds great!
Wicked sporty man 🤘🏻
When my wife's 48 is out of warranty I may do something like this to hers!
Nice bike . Good engine build . Enjoy the ride which I’m sure you do . Sounds good 😊
Matt great work as usual....can you make or briefly talk about the new fines in regards to custom exhausts in California?
Yea. I might try to make a video or Instagram post or something. Thanks for the suggestion.
Thanks for the reply and consideration...pretty worried my exhaust (TBR) is crazy loud...$1000?!? 1st offense is ridiculous as I hear
Awesome ride!!! Sounds amazing.
Good job that’s a nice ride
What tires would you recommend to run with your build?
I absolutely love it! All H-D "Heart & Soul"! I also own a 2011 XR1200x which I really love. A true Harley through and through. Still sad that you got rid of the Heritage. It was totally badass. The person who bought it is very lucky indeed. :)
The XR 1200 is a cool bike man. Thanks for the comment. Enjoy.
Thanks Matt! Whenever people see it, It's the one I get asked the most questions about. Very cool & fun to ride. My only complaints are that it lacks power compared to other V-Twin sport bikes and the 5 speed transmission. It should have a 6. Still, I totally love it and plan to keep it forever. It's 100% original - no mods whatsoever. ;)
@@MattLaidlaw The XR1200X is the ultimate air cooled Harley Davidson ever produced. The handling is excellent(especially with the rearsets) & I've always wondered how high one could go on the horsepower wars. Only real problem is the weight...
Do you still have this bike? How is it holding up?
What external breather, catch can and hose length is that? I definitely need one, I have an issue with oil leaking onto the top of my primary and pooling as the bike cools down.
when I first seen a roadster I was like who would want that lol well im to the want part of that story
love the videos.....such a badass bike
You went over the rear shocks but I didn’t hear the length. Can you share that info please. I like the way it sits
I believe they are 13 inch
Beautifully built! Seems to perform outstanding, I wish him many happy miles! 🙌
Hey Jamie! Are you happy with the cobra el diablo? And did you consider the bassani RR3? Also, your el diablo is 2.5 inch or 3.5 Inch? Thanks man!
Awesome bike 👌
I’m trying to build my own sportster tracker and want to add a hammer big bore kit. I am curious is it required after install to remap the ecu?
When you’re ready to change bikes again, I’ll buy this one from you!
