Harley Dyna by Kraus Motor Co.

Nick saw a Dyna that I had built for myself a couple years ago and liked it.  He asked if I would build him up one with a similar styling; Aggressive and made to ride hard.  

The bike isn’t flashy or colorful but it looks clean and simple.  My Dyna had an aggressive supermoto style to it.    With Nicks bike I wanted to do something that would still appeal to Harley rider since one of Nicks favorite bikes is his FXR.  So thinking along the lines of minimal and to the point we stripped a stock 2000 FXDX down to the frame and motor. 

Through out the stock front end, bars and controls, wheels, brakes…  All the crap that sucked.  Basically everything except the frame motor and trany.  We even scrapped the heavy closed wet primary.  The only mods to the frame were to cut off the battery box mounts, the electrics box on the left side and trim the rear fender horns down to less than half their stock length.  We built up a new battery box and mounted it between the leftover fender horns.

The custom aluminum side panels perfectly follow the stock frame curves and house all the stock electronics in the triangle under the seat.  We built an aluminum tail section that rests on the new battery box and embedded the taillight and blinkers in a strip across the back. 

The tank has a flat bottom that gives the bike a low look.  We gave the top of the tank a nice molding and through on one of our Large Moto gas caps.  I stopped by my friend Sandy Kosmans shop and searched through some of his old goodies to find a set of Kosman trees with a similar offset as the stock Dyna ones.  Had to do a little machining to get them to fit our application but running parts made by a motorcycle legend is all worth it.

The front forks came from a GSXR1000.  We shaved the right caliper mounts and are only running the left side Tokico brakes up front.   Coupled with a 320mm PM Floating Rotor the bike stops nice and fast.   We grabbed a set of PM wheels and fitted them up with some Metzler rubber.   We built the headlight out of Aluminum to give the bike a little streamlining and carry the Aluminum through to the front end.  Also added some trick fork covers down on the bottom of the forks. 

The rear brake setup on this bike is pretty trick.  We mounted a 4 piston Tokico caliper on the left side of the rear wheel just in board of the sprocket.  Made a hub spacer that separated the brake rotor and sprocket so the brake is between the sprocket and wheel. It hides the brake nicely allowing for a super clean right side and also keeps from relying on a sprocket brake.  This gives us the opportunity to change rear spockets for optimum gearing and allows for a performance rear brake with out the greasy pads.  We took off the 10 pound passenger foot peg mounts and mounted some clean aluminum pegs directly to the swingarm. Taking weight off in every way possible helps make a Dyna a whole lot more fun to ride.  It becomes agile and responsive.  We cut up a motor plate for a softail BDL open belt drive setup so that it would mount up to the Dyna.  Mounted the primary and made up a small aluminum belt guard to protect Nicks fancy jeans. 

We went ahead and dressed the engine up a little, through on a K&N air filter, and made a set of 2 into 1 pipes with a stainless reverse cone.  Unlike some others these pipes allowed us to run mid foot controls.  The mids are Custom and just simple and clean. No need to get to fancy, but they work great.  We also left the forward control mounts on the frame so if Nick ever wants to mount up some high way pegs for a long haul he easily can. 

To complete the riders ergonomics we bent up some 1 inch tubing for a set of bars that are just about right.  We called up Gard at LA County Choprods and got a pair of ISR hand controls sent over.  On my bike I used Acerbis plastic hand guards that are very functional but for this we fabbed up some custom aluminum hand guards that will help keep the wind off and protect Nicks fingers and levers from making contact with mirrors while splitting lanes.

Nothing worse than having a cars mirror grab a whole lot of front brake for you.  We scrapped out the big heavy stock gauges and setup a digital Trail Tech Vapor.  It’s light and functional.  The bikes blinkers are super bright LED’s tucked away out of sight.  Nicks Dyna is all about function with good looks, a Harley the way we build them.   He is planning to ride the hell out of the bike and I hope he doe
