looks like its from dratv definitly quality stuff. It would work with a 49.5 crank or a 54mm crank.

49.5 stroke by 54 bore would equal a 114 "awesome set up its what i have on my scoot.

or 54 stroke by 54 bore would equal a 124 even better than a 114.

For 100 bucks thats a steal someone should pick this up.

Do you mind posting a pic of the piston out of the rapper??? I may want to scoop this.

thanks
