metric allen wrench set, 6 way screwdriver, adjustable crescent wrench, some 1/4 inch drive sockets (8, 10, 12, 13 mm) and ratchet some metric gear wrenches, battery tender or some way to get a jump. and some straps. thats pretty much what I carry, enough to get the seat and tank off, tighten chain, pretty basic stuff and it all fits in my fork bag
