I changed my stock gearing last night to a 15 countersprocket and the difference is amazing.. It really feels like it hauls ass now to about 80mph , then if you open wider .. 100mph comes quickly The reason i changed was for dual sporting rides. I did dirt earlier too and 3rd gear wheelies feel like they have more traction now ... Im not sure if i actually like it tho... the 14 front was quiet snappy. anybody else run this setup? what you think?
