Gabrielle. A Harley Dyna Wants To Become A Tracker.

1pepodyna2pepodyna3pepodynaDuring 13 frenetic years, custom building shop “Radical Custom” created some of the world’s fastest and best designed custom Ducatis. But because of a too hectic professional life, the fun of custom building was gone for French/Spanish builder Pepo Rosell, After a one year break to rethink his life, he realized that his passion for custom motorcycles was intact and decided to start a new shop with a new philosophy: less business and more fun working on many different brand platforms.

4pepodyna4bispepodynaThis Dyna is his first work on a Harley. A client dropped it at his Madrid based “Extreme Pepo” new shop with only one specific requirement. Make it a two-up. For the rest Rosell remained in charge, and since he loves the 60’s and 70’s dirt trackers, this particular style of bikes influenced this build. Paying homage to the glory days of flat track racing by emulating the pared down look of a dirt tracker is not easy when you need to provide a road legal custom motorcycle.

6pepodyna5pepodynaOne of the most popular platforms for street trackers is definitely the Yamaha XS650, with its reliable vertical twin once used by Kenny Roberts on the track. In the Harley lineup, the Sportster is another hugely popular street tracker platform. In fact, you can just buy the XR1200 which is based on the legendary XR750. So, what to do with a Dyna to be ridden with a passenger?

6bispepodyna9pepodynaFirst, modifying the rear subframe now supporting a seat taken from a Mash 500, a small retro styled bike sold in France. Then to give this Dyna a tracker attitude, a few essentials were necessary. You’ve got to have the wide handle bars flat track racers use for better leveraging around the corners. Rose installed classic motocross-style bars, replacing the Harley factory switches with compact sets from Motogadget. Speedo and oil pressure gauges were relocated near the rider’s left thigh.

8pepodynaFor more of the tracker look, the big Dyna gas tank had to be replaced by a smaller version fabricated from a modified Yamaha SR500. For weight improvement the rear fender is gone with a small taillight and the license plate now bracketed to the end seat support. The front and side number plates contribute to the racing look. Performance upgrade includes engine, a custom mesh breather, a Gonelli quick-open throttle, Suzuki GSX-R forks, 40-spoke rims, Pirelli’ MT66 tires, Hayabusa 6-piston calipers, 320 mm rotors, high performance brake lines and a GSX-R lever assemblies.

    The Dyba & the FXR are both attracting the interest of custom builders again,

  2. 2 Sean Mar 28th, 2016 at 8:22 am

    Pretty good.

    Not sure about the way the exhaust is run.

    This looks great. Very cool and well-balanced I’m not a fan of number plates on street bikes, but that’s a tiny, nit-picky thing compared to how well everything else about this bike works. It even has real tires on it! To me it feels more like a cb750 with the heart of a Dyna than a street tracker, but either way I’d ride the hell out of it.

    This is a cool design!

    Very nice motorcycle Pepo … I really like your “new philosophy: less business and more fun” …

    Sometimes there are things worth more than money …

    This particular bike I like,,also pedal controls are strait down instead of far forward..I’m 5 ft 3in,in my late 60’s,,I can handle this ez….

    Looks like the passenger’s right leg is going to get cooked…. for a 2up, don’t think that is right place for a exhaust

  11. 11 BobS Mar 28th, 2016 at 10:51 am

    My first thought, “Ooh, I’d like to ride that”. Well done.

    Best bike, to appear on this site, so far in 2016.

    Bare knuckle stripped down Dyna – what is not luuuuv?!? This is such valuable formula.

    If you can strip 40 – 50 lb from a Dyna, I reckon, the Moco will increase its target market by 50%

    Oh man, that is soooo tasteful! Looks like a ton of fun as well as a real beauty.

  14. 14 James just another crazy kiwi Mar 28th, 2016 at 1:54 pm

    Looks very smooth and aggressive, what does it weigh now .

    Remember when King Kenny rode the most crazy flat track MotorCylce the TZ 750 .
    Absolute insanity and total brilliance

    Nice bike. I would love to see Dynas go this direction, instead of the cookie cutter club bike. Very cool.

  16. 16 Most Hated Mar 28th, 2016 at 2:21 pm

    Very nice

  17. 17 Melinda Mar 28th, 2016 at 5:16 pm

    Really beautiful bike! Looks like it can pick up some serious speed. Thanks for the post.

  18. 18 NoH2oh Mar 28th, 2016 at 5:21 pm

    Very cool, and I think a good number of size challenged riders would give up their Sportsters for a more nimble Dyna. They really don’t need to weigh 700 freaking pounds.

    That seamed tank really makes one appreciate HD does not do them that way.

    Fairly sure someone else built a Dyna almost identical to this in the last year or so. Featured on this page as well.
    Note to the “designer”, flat board seats with no rear mudguard is no longer in fashion.

  20. 20 mkviz Mar 29th, 2016 at 12:34 pm

    Looks like an overgrown sportster 1200
