How would these races turn out?

Were wanting to race a 2006 Honda Recon VS a 2000 Yamaha Blaster, The Recon engin is 50 CC's more. Wich would win? Also a 2004 Toyota Corolla with 110 horsepower VS a 1993 Ford Aspire 68 horsepower. And one more..A Honda Recon VS the aspire. The aspires top speed will be faster, but let's say accellerating from 0 to 40 wich would win? Thanks. Just clearing the results up to someone. After we c what you think we will race for real.
