Here is a well written paper about oils and motorcycle oils.

There is also decent information on break-in there which I followed with great results. I changed out the initial factory fill at 700 miles and my 4-cylinder 1200cc does not use any oil or require topping off after 3000 miles or more driven each season.
There is also a First Edition of AMSOIL's Motorcycle Oil Analysis that is worth downloading but I was unable to find a link to it. You may come across it while researching the internet.
To make a long story short,
stick with a JASO MA oil. However the Heavy Duty Engine Oils (HDEO's) for diesel trucks are very popular for motorcycles.
Substituting anything else has to be done on the basis of solid knowledge. Be aware that your motorcycle will shear all but the most expensive oils rather quickly and change out will usually be needed within 2000-2500 miles. More money will buy a longer lasting lubricant.
Valvoline "Dino" oil for motorcycles in 10W-40 regularly retails at $3.99 per qt. but I've seen it on sale for $1-2 less.
I paid $7.50 a quart for Mobil 1 Racing 4T 10W-40 on a walk-in Manager's Special. It normally goes for $9.50 to $9.99.
AMSOIL has a "preferred customer" offering that will entitle you to a competitive price about -20% lower than retail.
Walmart is a good source of several motorcycle oils and several other oils decently priced.
Autozone and Advance Auto Parts are places to buy when oil is on sale.
I suggest you read up to determine what you want and then look around to pick up an oil when its on sale. Most motorcyclists keep a "stash" that is one or two oil and filter changes ahead.
Initially you may want to stay with a petroleum base oil so that break-in will not take several years longer.
Nice bike, BTW.
