This may have been answered on the forum somewhere already but I'm not having much luck finding it. Does a 1974 RD250 motor bolt up into a 1970 DS7 frame or are there mods needed? Thanks!
direct bolt in. r5/ds7/rd250/rd350(73-75) all direct bolt in swappable.
for posterity 400 fits bur rear mount is different but doable, and charging system different.
Good to know. Thanks!
