Looking for a monster

Hi, my names mike, im 23. Im mostly into cars but i've always had an interest in getting a bike to ride and mess around with.

I really liked the look of the monster and it's what ive got my mind set on now.I have mostly been looking at 600s.

Im basically after something that might need a little work to a full rebuild, as i'd like to learn about rebuilding one. I haven't taken my test yet so im not in a rush for it to be finished.

What i wanted to know though is would a 600 bike be suitable for someone who is a new rider? Also, is there an advantage to the new injection bikes over an older bike? I would only be riding it during the warmer months to work and at weekends.

Any input is appreciated.

Thanks
Mike
