The Rapide isn't a huge issue as it has a magneto but the Egli has a battery coil. In short, Shorai batteries and vintage bikes are not the best idea.
The energy density of the LiFePO4 batteries is higher than a conventional battery, and the issue you're speaking of really only has to do with the Ah of the battery. You could probably fit 16 cells into a hollowed out battery case and have 30+ Ah vs 16 Ah on a large convential MC battery. Or maybe I'm not totally understanding the problem you're speaking of, but I've had an 8-cell on my Ducati for 3 years and it's been great (unless it's under 40 degrees out, but I'm guessing you don't need to ride the Vincents in that. The best part is that it starts even when I leave it for 2-3 months at a time while I'm at work.

It's an issue of load vs generator output. Much like the Shorai, the battery you reference needs a healthy voltage and wattage supply to maintain its charge. Seeing as the Alton only puts out 100 watts on average (150 peak) it falls on the inadequate side. Your Ducati puts out roughly 500 watts as comparison.
In the end, I temporarily ditched the case and added a similarly sized AGM (14ah) that I painted with black crinkle paint. An hour in the machine shop and I was all set with a suitable mount. The AGM should be forgiving enough for roller coaster loads and charge rates even if it is a little big and heavy.

Ah I see. Yeah the Li-polymers are much more particular about their inputs.

Having so much choice sounds awesome. Do you have pics of your garage?

Thanks for the pic. Looks like a nice job.

Just picked up a motorcycle jack off of Craigslist today for $20.

Let the mods commence.

Is that Billy Joel's garage?

Q for anyone- I recently sold my track car and want to take up moyorcycles. Thinking about one of those new 500cc honda cbrs to learn on. Any reason that wouldnt be a good move?

Saw this for sale on craigslist the other day, on 06 MV August Brutale 910.   Only $8k

 

 

Now this made my lil winkie stand up.

Conventional wisdom is that you should start on a smaller bike (125cc or 250cc) and once you're comfortable, then progress to a larger one. Don't forget that you're quite likely to drop the bike a couple of times when you're learning so you might want to do that on a beater bike and then sell it to another beginner when you're ready to go bigger.

The bike itself is good, but as TRINI points out, typically it's recommended that you start on a smaller bike. Overseas, you're legally stuck with 125cc for a year or two. New riders normally assume this is to prevent antics like speeding, wheelies, stoppies, and such. Really, it's to provide something of a reaction envelope while you gain experience with the controls - too much throttle or brake at the wrong time can have dire consequences with 500cc, while with considerably less horsepower you can back-off or correct before disaster strikes. And, imo, someone coming from a car needs to adjust to the sort of constant vigilance that riding a motorcycle requires - the pothole you missed seeing in a car could have you lying in the road on a bike.

Moving from a dirtbike to street, the uncle that taught me to ride insisted I get something bigger than the Honda 175 I liked, then bitched every time I had a close call on the 400cc bike I wound up with (grr!). We argued about engine size and horsepower requirements the rest of his life - to him, nothing less than 1000cc was worth riding, while the largest engine I've had is my Honda NT650 (which I've still got). If I were starting out now, I'd get a lightly-used Ninja 300 or CBR250R.
