i know my 480 is at more than 47.5 to the wheel...they were at 51 stock and i got a .80 over bore in it with a couple other mods...id say its got about 60. i know the 90's 500's put out somthing like 61HP stock...if i had to guess i'd say its somwhere from 55-60.

Good luck riding the 86 500 as fast as the bozos on newer 450's! Other than drag racing. On a track, that newer frame and suspension will walk away. Hence the Service Powersports AF bikes!
