Lightening the load. 

Dealing with power challenged motorcycles.

As motorcycles get more advanced they also need more power for themselves.  This can leave less power  for the rider to add the accessories we like.  We will examine the priorities and needs of a long distance rider and attempt to help you get the most you can from what you have.

Why?  Where does the power go?

Current motorcycle electrical load includes the normal lights and indicators.  Newer motorcycles made for touring applications will often have the added loads of electric fuel pumps, electronic fuel delivery, abs sensors,  the computer tying these together.  Some motorcycles are now fly by wire, and must have correct voltages to deal with all the input the computer receives.  Some motorcycles have electric assisted braking, electric center stands, electric windsheilds and self adjusting suspension.

Priorities

In the long distance community, the normal priorities are:

  Safety
  Comfort
  Riding accessories
  Routing accessories

Safety Items

When upgrading safety items the largest consumers of power are lighting.  Recent tecnological advances on low power high out lighting have become available through HID (High-intensity discharge) lamps.

You can save about 25 watts and get better lighting by going to a HID lamp.

HID Cautions
  High beam
   HID should not normally be used for high beam lamps because of the start-up time.

  Focusing
   Focusing can be a problem.  Putting HID bulbs into a standard headlamp can be a problem.  The pattern and cutoff needs to be the same as original.

  Temperature
   Use 4300k-5000k

LED Lamps

  Most LED lamps are designed for replacement of turn and brake lamps.  A typical 1157 bulb can chew up 25 watts while the equivalent LED 3 watts.

Emergency beacons

  Spot
  SARLink™

Comfort

Riding long hours in all kinds of weather requires that the rider be prepared for hot and cold weather.  In cold weather we often resort to heated clothing.  This includes jackets, pants, gloves and socks.  Using a rheostat   (Potentiometer) will waste precious watts.  Instead, these should  be controlled with an electronic switch, like a heat-trollertm or Gerbing’s  Portable Temp Controller.  These use very little power, passing it on to the controller item digitally.  You can use them for:

  Heated Grips
  Heated Seats
  Heated clothing

If you are getting short on available power,  the following are the first items to either not install or the first to turn off.

Riding accessories

  Radar detectors
  Communications
  Entertainment items (radio, ipod, etc)

Routing accessories

  GPS
  Laptop

Installation

Tight connections and large wire will help you get the most power to the device that needs it and not just heating up the wire that delivers it there.
