Ken Kirby's XL1200/1250 Sportster


Ken Kirby's XL1200/1250 Sportster

How do you make a 2003 Sportster fast? Do what Ken did and treat it to a set of HAMMER PERFORMANCE CRUSH XB Heads over the top of a 30 degree reverse dome 1250 kit! A set of our high tech IMPACT 560 cams, and a Thunderheader exhaust complete the package. It all adds up to one beautiful and fast Sportster, congratulations Ken!



Terry Flynn's XL883/1250 Sportster


Terry Flynn's XL883/1250 Sportster

If you think you're looking at another mild mannered 883, look again, Terry's bike lays down an impressive 110.7 horsepower thanks to his HAMMER PERFORMANCE CRUSH Ported XB heads, HAMMER PERFORMANCE 1250 kit, Air Hammer air cleaner, and a set of Screamin Eagle 575 cams. Hang on tight Terry!

Steve's goal was a 10 second street/strip Sportster, and it's common knowledge that a HAMMER PERFORMANCE bolt-on 1250 kit is a key ingredient of that plan. Beautiful bike, congrats Steve!

Francesco Corrente's Buell S1 Lightning


Francesco Corrente's Buell S1 Lightning

This beautiful S1 is sports a set of HAMMER PERFORMANCE IMPACT XB Heads working in perfect harmony with it's HAMMER 30 degree reverse dome 1250 kit. According to Francesco, the motor pulls like crazy from 3000 to 6000rpm and 2nd gear roll-on power wheelies are no problem at all. Sounds like great fun, congratulations Francesco!



Scott Mattner's XL883/1250 Sportster


Scott Mattner's XL883/1250 Sportster

This Iron from down under isn't just beautiful, it's FAST too, because it has HAMMER's 100hp 883/1250 conversion package! SMASH head porting on 883 heads and a 1250 kit with trick 30 degree reverse dome setup, IMPACT 560 cams, and an Air Hammer air cleaner get it done. Congratulations Scott!



Rick Taylor's XL883/1250 Sportster


Rick Taylor's XL883/1250 Sportster

Nothing like 100 ponies to the back wheel of a little 883! Rick's bike lays down the century mark thanks to SMASH head porting on his original 883 heads sitting over a 1250 kit with trick 30 degree reverse dome setup and a set of IMPACT 560 cams. Congratulations Rick!

Brodie Brimble's XL883/1250 Sportster


Slapster's XL883/1250 Sportster

Slapster is one of our many valued customers from Australia. His XL883 Iron got treated to CRUSH head porting to XL1200 heads and a 1250 kit with the trick 30 degree reverse dome setup and a set of IMPACT 560 cams, making his Iron one of the baddest Sportsters you'll find "down under", or anywhere else for that matter. Congratulations Slapster!



Dave Wilhdlm and his 2005 Road Glide


Dave Wilhdlm and his 2005 Road Glide

It's not easy being green! But it Dave's case, green means one mean machine! Dave brought us his mild mannered 88 cubic Road Glide and asked for some more go. We fitted up a 98 cubic inch bolt-on big bore kit and then treated the heads to our exclusive "SLEDGE" CNC porting service. Paired with a set of Wood TW68S cams, the green monster now puts 120hp to the back tire! This is a big bike that absolutely rips, congratulations Dave!



John Helfer's 2006 Sportster


John Helfer's 2006 Sportster

Brought back from a basket case, this beautiful bike puts the Sport back in Sportster! That's because it has our exclusive "CRUSH" CNC porting as well as a HAMMER PERFORMANCE Bolt-On 1250 Kit with our trick 30 degree reverse dome pistons and perfectly matched CRUSH 600 cams. It breathes through one of our massive Air Hammer Air Cleaners, and a Mikuni HSR45 carburetor mounted to a HAMMER Billet intake manifold. It's a package proven to be capable of over 110hp, congrats John!



Tyler Woodard's 2007 Sportster


Tyler Woodard's 2007 Sportster

Holy smokes what a beautiful bike! But what you can't see in the photo is a very potent HAMMER PERFORMANCE engine package! It starts with the "SMASH" CNC porting done to the original 883 heads. Those beautiful heads sit over a HAMMER PERFORMANCE Bolt-On 1250 Kit with state-of-the-art ultra light 30 degree reverse dome pistons. HAMMER's exclusive IMPACT 560 cams make sure the engine gets all the air it needs and does it quietly, and the incredible Patriot Defender exhaust and Dynojet Powervision tuner top off the package. This bike gets with the program and looks great doing it, congratulations Tyler!



Ian Hunter's Sportster


Aaron Thomas' 1990 Sportster

What started life as a plain jane mild mannered 1990 883 has been transformed into the beauty you see here! This baby goes as good as it looks, too, thanks to the HAMMER PERFORMANCE "SMASH" CNC porting treatment to the original 883 heads, along with a matching HAMMER PERFORMANCE Bolt-On 1250 Kit equipped with our ultra trick 30 degree reverse dome pistons. A HAMMER PERFORMANCE Billet Intake Manifold, Mikuni HSR42 carburetor, Andrews N4 cams and an RB Racing pipe top off the potent package. Congrats and hang on tight Aaron!



Ian Hunter's Sportster


Ian Hunter's Sportster

Ian sent us some great pictures, but it wasn't hard at all to pick from them, this charming shot of his grandkids with his Sportster really stood out! The kids having fun is precious, but Ian's 2006 1200R is a monster with it's HAMMER PERFORMANCE "SLEDGE" CNC ported heads, a HAMMER/Axtell 88 cubic inch kit, and a set of Wood .630 lift cams! Enjoy the kids and the bike Ian!



Matt Matthews' Buell X1


Matt Matthews' Buell X1

This little red Buell is a rocket! That's because it's been treated to the HAMMER PERFORMANCE CRUSH CNC Porting Service, Bolt-On 1250 Kit with our trick 30 degree reverse dome pistons, and CRUSH 600 cams! With no tuning, this baby cranked off a 107hp dyno pull at a bike rally. Holy smokes, hang on tight Matt!



Leo Lumbreras' Sportster


Leo Lumbreras' 2005 Sportster

Some bikes just look like they're going 200mph while they're sitting still. Leo's bike has that act handled! And this bike goes as good as it looks, thanks to the HAMMER PERFORMANCE IMPACT CNC Ported heads, Bolt-On 1250 Kit, and IMPACT 560 cams! Congratulations on a fast and beautiful bike Leo!



Shane George on his Buell S1


Shane George and His Buell S1

When I look at Shane's Buell S1, a George Thorogood song starts playing in my head, because this baby is Bad to the Bone! A set of SMASH CNC Ported XB heads and a HAMMER Bolt-On 1250 Kit are only the beginning. Red Shift 585 cams with JIMS Hydrosolid lifters, Sledge Hammer Pushrods, and an Air Hammer Air Cleaner feeding a giant Mikuni HSR45 carb and a Buell Race Kit exhaust all make this little S1 scary fast. Good thing he's got those suspension and brake upgrades too! Congratulations on a terrific job, Shane!



John Plaster on his Sportster


XLDukes and His 2000 Sportster (John Plaster)

If you're at the track and you find yourself lining up next to John, don't be fooled into thinking he's on a mild mannered little 883! John's Sportster  is equipped with a genuine HAMMER PERFORMANCE 1250 kit as well as CRUSH CNC Ported Buell XB Heads and CRUSH 600 cams. The combination puts over 103hp to the back tire! He's running low 11's at the moment but look for him to run the 10's as he gets this screamer dialed in. Congratulations John!

UPDATE 9/15/12: John has not only started running well into the 10's, he also scored his first win!


John Plaster in the Winner's Circle



Congratulations John and nice shirt!



Daniel Nilsson's Sportster


Daniel Nilsson's 2000 Sportster

Daniel's beautiful Sportster is yellow because it's on FIRE! It's equipped with a HAMMER PERFORMANCE 90 cubic inch kit, HAMMER "Smash" CNC Ported XL1200R Cylinder Heads, a set of Screamin Eagle .536 cams, and a Supertrapp 2 into 1 exhaust. If you're driving in Sweden and you see a yellow streak pass you like you threw out an anchor, that was probably Daniel rolling on the throttle. Congratulations!



Scott Evans and his 2004 Sportster


Grind and his 2004 Sportster (Scott Evans)

It's HAMMER Time for Scott Evans! While Scott sports his new HAMMER PERFORMANCE T-Shirt, his 2004 XL1200C sports a HAMMER PERFORMANCE Bolt-on 1250 Kit, HAMMER "Crush" CNC Ported Cylinder Heads, and a set of Red Shift 585 Cams. Scott and his bike have all the tools needed to Pound the Competition, congratulations Scott!



Scott Clifford's 1989 Sportster


Scott Clifford's 1989 Sportster

Who says 4-speed Sporty's are obsolete? Scott's '89 XL883 has some real crushing horsepower now that it's equipped with the most advanced 1250 kit on the market! In Scott's own words, it's "a totally different machine" Congrats Scott and enjoy your new found power!



Chris Bennett's 88ci XB Motor


Chris Bennett's 88ci XB Motor!

Chris wanted to make his Buell XB12 into a fire breathing monster, so he brought his motor to HAMMER PERFORMANCE to have it built. The result is what you see here, a work of art equipped with a HAMMER/Axtell 88ci engine kit and topped with a set of HAMMER Sledge CNC ported cylinder heads and ported throttle body. In a lightweight XB chassis this thing is going to be scary fast!




Madnss's 1992 Sportster (Ryan Dhabalt)!

Hear that wicked sound? Ryan's Sportster sounds that way because it's now equipped with a HAMMER PERFORMANCE 1250 Kit and CRUSH CNC ported XB heads! The 1250 kit he chose uses 15 degree Thunderstorm style Sledge Hammer Pistons and the chambers in his heads have been machined to match, giving the ultimate in chamber efficiency and breathing. An AIR HAMMER Air Cleaner feeds his Mikuni carb through a HAMMER ported intake manifold as well, ensuring this monster never runs out of breath. A set of SE .575 lift cams and Sledge Hammer pushrods handle the valve train duties. A Daytona Twin Tec Ignition and a Rich Products Thunderheader round out the combination. Yes, there's a reason it sounds like that, this is a POTENT combination sure to light up the back tire or lift the front end at will. Hang on tight Ryan!



Jerod McCarter's 2009 XL1200C


Jerod McCarter's 2009 XL1200C!

The reason Jerod is smiling is because his beautiful Sportster is now equipped with a HAMMER PERFORMANCE 1250 Kit and Smash CNC ported cylinder heads. Coupled with a set of SE .536 lift cams and Sledge Hammer pushrods, Jerod has a proven combination for making great torque and power with reliability and longevity. Great job Jerod, enjoy the ride!



Keith Goforth's Sportster


Keith Goforth's Sportster!

This sharp looking bobber-style Sporty runs as good as it looks thanks to the HAMMER PERFORMANCE Smash CNC ported cylinder heads and bolt-on 1250 Kit! A set of SE .536 lift cams and Sledge Hammer pushrods rounds out this potent combination. Congrats Keith!



Larry Gross


Larry Gross's 2006 Dyna!

Larry's ready to pound his competition! That's because his Dyna now sports a Hammer Performance 98 cubic inch bolt-on big bore kit as well as a set of Smash CNC ported cylinder heads! Toss in a set of S&S 585 cams and in Larry's own words: "This Dyna Wide Glide runs great, Iím glad I found Hammer Performance to do my engine work." Thanks and congrats on the great bike Larry!



Rejean Primeau


Rejean Primeau's XL1250R!

Rejean is the proud owner of this beautiful 883R. But it's not a mild mannered 883 anymore, as Rejean installed a Hammer Performance 1250 Kit! A TC88 ignition gets the curve just right for the bigger motor. Congratulations Rejean!



Dale Nillis


Dale Nillis' 125hp Buell!

Dale set out to pound his competition, and the result is a fire-breathing 125 horsepower Buell X1! He got that result using an 88 Inch Kit and Sledge Head Porting service from Hammer Performance. A set of S&S 600 cams handles the valve motion and a Force Big Bore exhaust handles the exhausting chores. Be careful if you challenge Dale to a race, you're liable to be crushed!



Dana Schauer


Dana Schauer's 101hp Sportster!

At first glance, Dana Schauer's 2010 Sportster might be mistaken for a mild mannered 883. But one twist of the throttle will dispel that notion when it puts it's 101.7 horsepower to the back tire! Dana's bike is equipped with a Hammer Performance 1250 Kit and Smash Head Porting service. He's also running a set of SE .575 cams and a Supertrapp pipe. Take a good look at the photo because with power like that in a Sportster, you'll be looking at this bike from behind it!



Dave Spetman


Dave and Patty Spetman and their 100hp Buell X1!

Dave and Patty brought their X1 to Hammer Performance for a 1250 Kit and Smash Head Porting service. Coupled with a set of SE .536 cams, a Force pipe, and a tune-up, they left with a 100 horsepower monster. Congratulations Dave and Patty!
