Wisconsin Department of Transportation officials say 2012 will be one of the deadliest years on record for motorcyclists.
So far, 102 people have died in motorcycle crashes this year, compared to 85 for all of 2011.
The figures show the average age of the victims has increased to 48, from 30 two decades ago.
State motorcycle safety manager Greg Patzer said older riders think they can just pick up where they left off as a younger rider, but that's not a good idea. He said returning riders may have rusty skill in operating their bikes.
The Milwaukee Journal Sentinel reported 21 people lost their lives in motorcycle crashes in September, making it the deadliest September of the decade.
