The "specs" mean nothing other than the recommended maximums the manufacturer thinks are "safe". With decent packs it is easy to pull well over 100 amps from that motor given a large enough prop. Example, the NAMBA speed record for a 4S rigger is 138 mph, the driver used a 36mm motor. Amp draw was north of 300 amps.
But a decent conservative setup can give great performance and not burn up your equipment. Try an m445 prop, speeds should be in the mid-50s with pretty low amp draw. Step up to an m645 and you should see 60s still keeping amp draw below 100.
