To both the street and the track will tell you Justin and Jarrod Del Prado, the duo working as brothers and best friends at reputable DP Custom Cycles. A Sportster-based machine that they designed and tuned to excel in all aspects of street and track performance if in the hands of an aggressive and capable rider. As demonstrated by the past features I published, the humble bros have always produced very cool customs, and with this new creation stay true to their unique style.
To perform, no expense was spared. The motor was rebuilt at the shop with Revolution Performance polished and ported heads, performance cylinders, pistons, and hot Screamin’ Eagle high lift cams. The single fire ignition and coil are by Dynatek. The motor now breathes through a 42mm Mikuni carburetor, with Justin & Jarrod fabbing the tuned 2 into 1 exhaust. All the engine works to create a fresh and beautiful 1250 cc motor now shining in a bright aluminum ultra-thin coating commonly used on firearms.
Every single piece of this bike has been fabricated and engineered to the highest standards. Starting by the rear subframe and the race inspired steel tail section. Correct stance was achieved by lifting the rear with Ohlins shocks and lowering the front with shortened Ohlins inverted front forks. A one-off triple tree, a set of clip-ons and of rear-sets are works of art fabricated by the Del Prados’ pal Shane at Chainsikle. An increase in bike trail and a Scott’s steering damper neatly engineered to be mounted with the arm mounted out of sight contribute to improved riding stability.
During the build, the bros obsessed with reduction of weight anywhere possible. First using a lightweight Lithium Ion Ballistic performance battery placed in the tail section. Then, by fitting the Mack with a lightweight aluminum swingarm that they designed at the shop and ordered to be produced by Trac Dynamics, and using carbon fiber BST wheels rolling on Pirelli Diablo Supercorsa (suitable for use on the racetrack and on the road for motorcycles with a top speed of more than 168 mph or 270 km/h)… Both front and rear brakes are Brembo mono blocs activated by ISR master cylinders on Brembo rotors. The adjustable hand controls and turn signal mini switches are also from ISR.
For details, twin headlamps and turn signals are LED’s. The diamond stitched seat is upholstered in Alcantara, an artificial substitute for suede leather and the ultimate material for aircraft, custom cars, jet and yacht interiors.
Paint by Walkers Way is Porsche’s Carbon Effect and Voodoo Blue on which was sprayed a matte finish clear coat. And if you wonder why this dual street and track Sportster racer is called Mack, it’s because the client is so happy with his DP ride that he swore to never sell it and instead give it to his son nicknamed “Mack”.
The Del Prados kept their original passion for what they do for a living. And it shows. With for consequence that all their clients, without exception, became good friends… DP Custom Cycles (photography @ DP For Cyril Huze)

Great machine
Sweet and it actually has real suspension and brakes too!
Love it. Belongs on the street where we can all play ☺
looking great and I bet riding great
Should belong to my garage!
Nice but you still have a Sportster motor and gearbox.
Sportster motor, dependable, simple, plenty of power if modified And CHEAP! 2003 and previous engines have a trap door to remove the gearbox which hasn’t been changed a lot for over 35 years,Fairly strong. Nice bike!!!! ..Z
These fabulously talented brothers and I live in the same community. To say that they assemble fine, sculpted and well machined instruments is the understatement of the Century.
Way to go guys, another iconic machine hits the road from your shop.
Great work the brothers.
That is a VERY nice bike…really well thought out and executed.
Very good looking machine. Bravo!
Form following function, as it should.
Very excellent indeed…… 🙂
-nicker-
Very well done. I luv it.
Yes, I’d ride it…might get back ache but I’ll suffer gladly
Come to think of it, its a ‘Ride to Work’ bike.. the long windy, hilly and fast way to work….
A and B roads as we have here in southern England..
Very Nice, for that kind of style !!!
Be a blast on the twisties
But not for my old rear end !
LOL !!!
Needs a front fender if not only for looks, and I’d change the oil “bag” to one like on the Buell S2, and while I am on a Knob Creek induced tirade I’d change the over specified forks to a traditional Ceriani or such, but overall I like it. Sad HD will not make a sporty Sportster. Good thing pre-hipster ones are so cheap now.
I like it!!! Good job guys.
