Anyone seen an rpm to speed chart, with front and rear sprocket size as the reference.
ie. an atv has a 13t front, and a 38t rear and runs at about 6000 rpms as an example.
I guess you would need tire diameter also say 22in. perhaps

 

HPD and Aaen have charts on their web site's

 

Umm handycap, i have been looking for like 45minutes on their sites and could not find one on either site. Where should i look?
