Even though it is NOT the right oil, using it is not going to damage anything in your engine. The zinc and phosphorous package is a little light, compared to other motor oils (Zinc and phosphorous are important anti-wear agents in the oil formulation), but it is more than enough to provide the wear protection you are worried about.
The easiest way to tell if you got the right oil for your bike is to look at the back label. On the API rating shield, a motorcycle specific oil will say JASO MA/MA2, meaning that oil has been tested and found compliant by the API for motorcycle use.
When selecting non-tested or non-motorcycle-specific oils, you have to be careful and do your homework on what the manufacturer used when they blended the oil. Many use friction modifiers in place of high zinc and phosphorous packages, including teflon, molybdenum and a host of other substances to improve lubricity. While in an automotive engine, this reduces friction and improves efficiency, in a motorcycle engine, it will spell doom for your wet clutch. Those friction modifiers will become trapped in the clutch lining and it will start to slip. Once that happens, you have no choice but to replace the clutch.
The other thing to watch out for with non-motorcycle-specific oils is the oil's shear resistance. Because the bike uses a shared bath lubrication system, the transmission gears use the same oil as the crankcase, meaning the oil is subjected to substantially more heat, pressure and shearing forces than it may be intended for.
Did you screw up? Probably not. Would I use it in my bike? No. But that's just me.
