To be honest with you, my only personal experience was with a 748 that was admittedly perfectly reliable for the six months I owned it, including several rides in the rain.
OTOH, I know several long term owners -- although again, not Monsters -- that experienced electrical difficulties with less than 20,000 miles on the clock.
Myself, I think the Duc reputation for balky electrics is probably deserved. I'd love to own one of their modern retros, but I don't believe I'd ever fully trust it. As far as I'm concerned, when the word "reliable" is mentioned, the conversation begins and ends with Honda.
< edit > Oops, I didn't realize you were the one who started the thread. Goofball. Honestly, I second (or third, or whatever) the motion to buy the VFR. I'd like one myself. Second vote would be for the 600RR. Not nearly as practical, but might be better at scratching the sportbike itch you seem to have, eh?
