I'm kind of embarrassed to admit how many bikes we have. Started out on a pair of Honda Rebels, then Pete got a Triumph Bonne America and I got a Honda Shadow Aero.
Next came the Guzzi's. Cali EV, 750 Breva, Nevada.
Then the R45 and the C. Then Pete decided a baby Ninja would be a cheap, fun bike to have. Nevada got damaged when Pete hit a coyote one dark, overcast night. Guzzi dealer in Seattle made him an offer he couldn't refuse on a new Nevada, so now there's two. Harley mechanic had to trim the herd and so the R80 joined the group. Really like the 650GS's and heard that the last shipment was on its way here, so we picked up a pair. Last Valentines Day, he surprised me with a little Honda CRF230L, (and a new CZ 550 varmit gun). And most recently, a friend of ours decided he is no longer able to ride on two wheels, and he's had his R100 since it was new. And he needed the $$, so we bought it and his other bike, a 1998 Guzzi V11 EV. Didn't really need the EV, but now I have one of my own, to go with the Cali EV that Pete rides.
I know that if one of us wasn't interested in riding, there would only be one bike in the garage.
For some reason, we just can't seem to part with any of them. The Aero hardly ever gets ridden, even though it is the most comfy long distance bike we own. But its worth more to me sitting in the garage than what I might get for it, if I decide to sell it.
I like all the bikes, each of them has a purpose (well, MOST of them have a purpose, a couple were just...because....)
If it came down to being able to own only ONE bike each, it'll be a choice between the pair of GS's or the pair of Rebels. GS's can do more and have more power, but the Rebels get 85+ mpg when commuting and they are almost maintenance free. And I took my Rebel from WA to MN and back this summer. 5,000 miles and she rode like a dream.
I'm really looking forward to getting my 3 wheel endorsement, and I'd like to remove the useless(to me) fiberglass sidecar and replace it with a custom built 'crate'. So I can haul stuff. I'm already thinking about a refurbishment of the bike, it was an almost daily commute rig for its previous owner and is looking tired.
If I have the weekend off, the R45 will be heading to the Vintage Motorcycle Assoc yearly gathering at Vashon Island. Its going to get ridden a lot more, instead of being the garage queen she is now.

So many bikes out there, I'd REALLY like to have one of the new Guzzi V7 classics. purdy.......
