First bike was an old Yamaha 50cc moped, not the FS1E I wanted but the V50. Great thing and put up with a lot of abuse over fields.
Passed my test and got a GSXR250, a 4cyl 4stroke import, very quick off the mark, but my cousin trashed it. He ended up like Barry Sheen and attracts magnets now.
Replaced it with a 1983/4 GPZ900R. That was a great bike, went all round Europe with it and I regret selling it, but wife and young kids sort of guilted me into it.
I'm currently between bikes and negotiating for a Honda CB600 with a guy down the road, he's retired and doesn't ride any more. My play is to convince him it's a shame to leave it standing, and besides he has several others to look at.
