Dyna Street Tracker by Kraus Motor Co.

Dyna Street Tracker

Kraus, based out of Santa Rosa, builds high-performance brake and suspension products for American v-twins, as well as complete customs.  Today we have the Kraus “Dynamite,” a Dyna-based street tracker that promises to run and handle as well as it looks.

Most Harley trackers we see are based on Sportsters, but Kraus took a different approach, focusing on the Dyna platform.  The base is a 2001 Harley FXD with a Twin-Cam 107 built by Dave Bozzie that revs to 8000 rpm.  Here’s what Kraus had to say of the motor:

We took almost 4 lbs out of the flywheel, polished, welded and balanced it.  Keeping the stroke stock Dave added displacement with bigger cylinders and pistons.  Feuling Parts provided one of their complete Bulletproof Geardrive Cam Chest kits, Beehive Valve springs and Titanium Keepers.  The Heads had about a weeks worth of work in them.  All the magic tricks!  The motor revs to 8000rpm with a very smooth climbing torque curve.  There’s a power band hit at 4,100 RPM than pulls your neck back.

Harley Dyna Custom

Up front, the bike is running the Kraus Dynamoto Inverted Front End Kit with Ohlins forks, a bolt-on kit that takes the guesswork out of USD fork swaps.  Out back is a custom swing arm machined out of 7075 aluminum that raises the rear height two inches for quicker turn-in.  The wheels are carbon fiber, coupled with four-piston radial brake calipers, and the bodywork is custom aluminum.  Of the riding experience, Kraus says:

I’ve done some big road trips on this bike already, usually making sure to find the windiest roads to travel on.  It handles the big open highways like a big bike should but also pitches into the corners with ease  and confidence.  It tracks very well, I have not found any ill handling issues.  The bike is tight and crisp and does not have any of the sloppy feeling of a Harley. 

It’s hard to imagine a better-handling–or better-looking–Dyna in existence.
