PCB Hand Control Switches

2021 HDM re-invested to unsister the tooling and offer Right Hand Board only!  The right board is usually the one that fails the most as it's used the most for run/off & Start.


While we had 0 returns on the prior version with over 2500 sets sold, we had the engineers relocate the brake sensor connection from any contact with the PCB screw as that was claimed to have caused grounding issues by aftermarket wiring manufacturers.  We also changed the clocking on the brake sensor connection to ensure easier wire routing away from the throttle cables.

3D Printing/Engineering

Starting in 2020 and continuing into 2021 HDM has invested in re-engineering & using top of the line 3D printing capabilities for side covers that have been previously hard to find.  3D printing at production level standards offers greater tensile & shear strength plastic than the original legacy molds.


We started with the 05-07 Pitbull & 05-11 Ridgeback side covers, and was able to offer them with reinforced with a heavy-duty thick side cover insert (skeleton) which your mounting bolts directly into the threaded assembly.


Next In-Line was the right side only for 05 Bulldog side covers.  Seems this is the one that seems to fail probably due to exhaust heat.  Constructed with a high grade composite to last longer.


We are continuing to review and meet customers expectations and have more in-line for 2022 in this space!



Vance & Hines 300 & 330 Hardtails

Limited options for 300 rear tires and exhaust these days.  Luckily Vance & Hines still makes the big radius for the Mastiff & K9 models with the corresponding exhaust bracket.  The rest of the models were left out to the wind as they have long discontinued any other model options.


HDM engineered custom exhaust brackets to fit the Vance & Hines pipes for the 300/330 hard tail models specifically 2005-2011 Pitbull & Ridgeback models.  The brackets are made of 1/4" thick steel, proper bends with zero welds to eliminate breakage, proper bolt hole alignment for easy mounting and powdercoated for long lasting life.  


V&H never made the 2-2 big radius pipes for the 330 models however with our bracket it fits like a glove!
