I'd love to own a V-twin. But The Guzzi just doesn't do it for me. Besides I have a BMW R65. The old BSA's are just way too expensive. The Harley I test rode had too small a fuel tank, the front rotors were warped and the bike was just too heavy. On a slight incline it almost rolled off the sidestand because I didn't leave it in gear. Oh and there was no center stand!!!!
The Ducatti is just too uncomfortable for me to ride. I thought Yamaha was going to make the beautiful XS-V1 but it didn't happen.
(sigh)

Another beautiful bike I can't have. The Dick Mann BSA Y13 750cc...

There was a Harley I wanted years ago. I saw it in Cycle World about 1978ish. Somebody took an XR dirt racing frame and put a big bore motor on it at about 1100cc, alloy wheels, tripple disks and a small headlamp. They claimed it would go 170 mph and I was in lust. Of course this bike was light, simple, nible and very very fast. Harley despite its long racing heritage will not even consider such a machine. The XR1200 street trackers that they make now are just so big and clunky looking that I find myself just walking away. The only real part of Harley that I would consider would be one of Eric Buells machines and Harley just amputated them. Unfortunately there is nothing Harley about a late model Buell.
My buddy Fast Ron Mass and his Buell 1125R liquid-cooled v-twin (purpose built Rotax motor) - the fastest motorcycle I have ever ridden.

Unfortunately I'm too tall for the Buell.
