I'll try to get them in the order of ownership, however that may be alot to ask;
1973 CB350 (4 cylinder, first street bike. Rode it for 2 seasons and about 15,000 miles. Sold it for the same $800 I paid for it)
197x CB450 (2 cyl. high pipe model, the 350 I thought at the time was faster, but this was bike #2 and 20,000 miles more experience)
1979 CB650C (fully dressed in Vetter, and a CB and a radio w/cassette player...lol and for some reason I still did wheelies on it and dragged the bags~yes they pulled off if dragged too hard~ and pipes on cloverleafs. but 75,000 miles of being a squidly on this bike. The engine finally rattled so bad I ran out and bought the Sabre)
1982 VF750 Sabre (Last time of allowing a friend to ride one of my bikes ever, ran over by a tow truck at an intersection jumping the light)
1982 GPZ550 (racebike 2:10+ lap times were "fast" but inconsistant)
1982 CB750C
1983 VF750F
1983 CB900C
1983 CX650Turbo
1984 GPZ550 (racebike #2 2:07 lap times were more normal and far more consistant)
1984 Seca550
1985 Ninja 600R (3 of them...1 was totalled racing in an endurance race ~not by me~-the other 2 were raced, 1 in production(doubled as a street bike), 1 in SS classes for 4 years each...both of these had over 30,000 miles on them when sold..finally broke the 2:00 mark at BIR)
1986 Ninja600 RX (aluminum framed . 50,000+ miles on that before selling in 92?)
GPZ750 turbo
1987 Ninja 250R (racebike #6)
1987 Ninja 250r (had given this to my brother for his 16th B-day. but he wheelied it into the principals car, so I took it back)
1982? Seca 920
1988 Ninja 600R (kept this bike for 19+ years and 256,000 miles and 2 Deer hits wihtout falling down)
1988 GSXR750 (racebike #7 never got this bike sorted for me but ran 1:52 lap times )
RD400 (owned for less than a month, got it in a basket, rode it for about 1000 miles)
1989 Ninja 250R (Racebike #8....Kept this bike for 21 years, it only ever saw the track....28,000 miles when I sold it last Feb...This bike I ran 2:00-2:015's at BIRs long course even with the then new turn 9....after attending CSS. I dropped several seconds per lap and was very consistant)
1989 EX500 (racebike #9&10)
1989 ZX7R
1989 FZR1000
1989&90 FZR600 (racebikes #11,12...finally pacing in the low 1:54's)
1990 ZX10
1991&92 CBR600F-2 (racebikes #13&14, finally broke past the 1:50 mark and could run 1:48 when really pushed)
1993 ZX11 (58,000 miles and broke the crank in half, rode it home from Topeka Kansas on 2 cylinders in '95...it never ran again)
1993 CBR900RR (owned maybe 3 weeks, raced 1 race weekend on it and sold it...but #15 nonetheless)
1985 RZ350
1982? Katana 1100 (the old silver one with a partial upper fairing)
1997 ZX6R
1998 GSXR600
1984 Venture Royale (a fixer upper project that ran well when done but looked terrible)
2001 ZX6R (in 2 years I had 65,000 miles on it when I sold it)
1992 Katana 750 (there was nothing about this bike I liked after riding it, likely I did not even put on 300 miles in the 3 months it took to dump it)
2003 R1 (Really didn't like it much, nor did it get ridden much, sold it in 2004)
2007 ZZR600, (pretty much a 2002 ZX6R)...currently the only bike I own, 68,000 miles on it, a Deer hit 2 years ago and again no fall down. Plan on breaking that 256,000 miles mark on this bike faster than I got there on the 88'. Lets see I started riding this July 2, 2008, so 4 full seasons average is only 17,000 per, so 15 years time.
Just about everyone of these was bought new except the CB350, Seca 920, RD400, FZR1000, Katana 1100, Venture Royal, Katana 750. The list does not include a few dirtbikes I owned before I was legal to ride on the street; XR80, XL125, YZ60, XR250R.
After the 900RR in early '93, the only racing I did was on the 250 Ninja until 2003 and even that was only at 1 or 2 Endurance events each year. That also happened to be the year I widdled down from the typical 6-10 bike garage to typical 3-4 at a time.
That '88 Ninja 600R and that '89 Ninja 250 were the longest kept bikes by far. Looking at the list, I must of had lots more disposable income than I do now, or perhaps it was my priorities, or both.
