The 1995 Maryland Ride For Kids outpaced last year's fund-raising event by nearly $15,000.
The charity, founded 12 years ago in Atlanta, raises money for pediatric brain tumor research by organizing motorcycle rides for pledges in a dozen cities across the country.
A caravan of about 400 cyclists raised $69,120 Sunday on a ride from Columbia to Westminster.
Several children, who are coping with the illness that has surpassed leukemia in the number of victims, went along as passengers of the cyclists.
Participants collected pledges and made their donations at The Mall in Columbia before traveling 52 miles to the Carroll County Agricultural Center in Westminster.
"Once again, motorcyclists in the Washington-Baltimore area showed they care," said Mike Traynor, founder of Ride For Kids, which is sponsored by American Honda Motor Co.
"This program reflects the true spirit of American motorcycling," Mr. Traynor said.
