The sad fact is that Ducati (and many others) used wire that is too small to do the job well. It works when brand-new, as many borderline parts and systems do, but will come to grief the first time anything is not 100%. Split hairs all you wish, but every Ducati out there, through early 2000s at minimum, has this inadequate wiring from the battery to ground, through the solenoid and to the starter terminal. If you have a brand-new, high-capacity battery and religiously clean everything in sight, you may get by for a time. In the end, replacing the wiring with the good stuff of your choice will save you from the need to wonder whether the motorcycle will start when you want to ride it. Michael's upgrades are worth buying for sheer quality and focus on value. Do what suits you, but don't knock the man for providing a great product that is badly needed, and at a good price.

Say Folks,
If anyone has questions about whether there is a big voltage drop,
please take the few minutes to view the Youtube videos on my site.
They both have a Fluke DVM shown in the image when the bikes are being
started. It is quite easy to see the big drops due to the excess
resistance in the OEM circuits. And to see that the big drops don't
happen with the HICAP in place.
I am now producing footage with a clamp-on DC current meter in the
image (along with the Fluke DVM) to show how the amount of current
demanded by the system fluctuates and hope to have some videos worth
viewing sometime in the coming week.
But the bottom line on starting a motorcycle is that if there is no
resistance in the starter circuit (as in - as little as can be
engineered - ) then virtually all motorcycles start up in 1-2 seconds
regardless of their compression ratio or other factors. That tells me
that the the starter circuit *should have* as little resistance to
current flow as possible. Because that quick startup reduces the load
and wear on the *expensive parts* in the circuit.
But cost considerations cause all manufacturers to use as low
performance components as they can to keep the final retail selling
price of the motorcycle as low as possible, so they are as price
competitive in the marketplace as possible.
The specification for the components state that they will work, and
when the bike is new they do start pretty quickly but as soon as a
little corrosion and use sets in they all start to have problems.
