there's 3 bikes in the garage, out of the 3 the Deauville is worth the most and is the one for sale.
V-strom 650 k6 - 36k miles
Deauville 700 K7 - 5kmiles
CX-500 - 1983 - 56kmiles
The Cx is in bits but was a laugh to ride and cost sod all is now a project I've been enjoying.
The strom is my everyday bike... I mean it gets used every day, to go to work, to go on holiday, to go offroad, to go to the shops, to scrape a few pegs. I love the thing, the engine's a peach. A good all round bike. Does everything OK and still puts a smile on your face every time. I'm sure you can inform him of the Strom's virtues.
The Deauville's concept is as a fuel efficient tourer/commuter. it's big to commute on and the steering is fairly heavy at slow speeds. Comfy for long periods. fairly upright sitting position. my legs (33" inside leg) are a bit long for the cut out sections along the bottom of the tank, but is OK. I put 25mm bar risers on it as I found the slight forward lean killed my bad back. Panniers are a tidy size and can be fitted with larger lids but are not removable apart for servicing. Shaft drive is low maintenance unlike chains. good clock layout (700 model) Good brakes and combined braking and ABS on Later models. Power is about the same as the strom but she's a fat bird doesn't pick up speed the same way the strom does. The mrs prefers pillion on the Deauville than the strom, but the strom is still comfy. Lots of options available.
there's a section on the Uk owners forum - SAD = Stopped And Dropped. when loaded with fuel she's quite top heavy and with a fairly lumpy engine (low low speed) many owners drop them. If buying second hand look for obvious damage to plastics. Don't get me wrong it's a great bike for what it was designed for, but I fell in love with the Strom.
