"The 54-year-old rider was particularly upset about having his licence suspended for 28 days and blamed police for 'ruining' his life," Ms Grace said.
"Instead he should be thanking our officer for potentially saving it."
There were too many similarities to the fatal bike crash the day before, she said.
"In the weekend's two incidents we had two male riders the same age on bikes of the same cc rating who were both breaching their learner licences.
"Unfortunately what my staff are finding is a lot of new or returning riders are overly confident and riding bikes that are too far beyond their experience and capabilities and coming to grief on our winding Coromandel roads."
Last year, 14 motorcyclists died on Waikato roads.
This year five people have died on Waikato roads in three crashes.
"That's the same number of fatalities for the whole month of January 2015 and we've still got Auckland Anniversary Weekend to go," Ms Grace said.
"We'll be maintaining a highly visible presence on our roads over the coming holiday weekend and what we're asking is for drivers and riders to know their limits.
"We've already seen that riding to impress can lead to a lot of stress -- or even worse. So know your limits and stick to them."
