ok now i am actually apologizing, i was in a bad mood
i must say, if youve been working exclusively with E50s so far, working with something variated will be a breath of fresh air. i was pretty much exclusively an E50 kinda guy from like mid-2008 till mid-2010 and i was getting SO fucking sick of working on them. now i have basically two hobbits, a motron (V1), a robin (G2), a moby (AV7), a pacer (M01) and a Si, so i have lots of exciting new engines to play with and its pretty exciting to get your hands into something new. its like starting all over again, but with enough logic and skills gained previously where the whole learning process is just a matter of taking the engine apart and putting it back together again, then making it fast.
the hobbit is a great engine, as are all the other ones. ALL the variated bikes can be made insanely fast, like SUPER fast. aside from vespas ive seen pretty much all of them break 70. (is there a 70+ vespa moped yet?) and ive seen all of them wheelie off the line.
variated bikes are pretty much the end of moped tuning. if you wanna have a bike that is satisfying throughout the entire range, go variated or go home. 1 and 2 speeds can be made to be really fast, but theres always comprimises. theres basically no comprimising on a variated bike.
that said, any of them are good choices. theres tons of performance parts available for all of them. they can all be made to do 40+ with almost entirely stock setups, and they get there quick too.
basically you cant go wrong, the choice is yours, youll be satisfied pretty much no matter what you go with.
