Installing a used 07 SV650 17 inch front wheel/fender on a 08 DL650 Vstrom experimental project.
Posted this on some other forums, too. Have a couple thousand miles on the conversion so far,
without any issues.
DL650 with original 19 inch front wheel:

DL650 with SV650 front wheel/fender installed before painting:


The original 08 DL650 front rotors would not fit the 07 SV650 front wheel due to the rotor mounting bolt circle being larger diameter on the 08 DL650.
07 SV650 wheel:

08 DL650 Wheel and Rotor:

Purchased a set of used 06 DL650 front rotors and they fit the 07 SV650 wheel. Before mounting the SV650 wheel, checked fit of 08 DL650 axle in 07 SV650 wheel/bearings and the 08 DL650 axle fit the same depth as it did in the 08 DL650 wheel/bearings. Also measured distance between original mounting surface of 08 DL650 rotors, compared to mounting surfaces on the SV650 wheel and both were the same. DL650 rotors are larger diameter than SV650 rotors, so 06 DL650 rotors were used to match the original diameter of the 08 DL650 rotors. The calipers are a tight fit removing/replacing the wheel/rotor and the caliper need to be "gently" rocked back & forth to expand the gap between the brake pads to remove.

Cuts made in SV650 fender as shown:





Gaps from 120/70/17 tire to fender front & back:
Rear:

Front:

The front mounting holes were drilled first about 11/16" to 3/4" from the center of the curve
above the hole to the center of the hole:

Left 1/4" gap as seen from the fender to the fork tube. Only drilled the front holes first to allow for tire clearance adjustment when drilling rear holes:

Purchased about $6 worth of mounting hardware from Lowes, material used: two 3/16"X1" fender washers, four nylon spacers 1/2"X.194"X1", two M6-1.00X30 bolts for the front, two M5-.80X40 bolts for the rear

Hardware from Lowes used as follows, cut the the front nylon spacers almost in half with about 25 degree angle on one end & drilled original ID hole large enough for front M6 bolts, used fender washers on inside of front fender and cut about 1/8" off of rear nylon spacers to use as washers on inside of rear fender, drilling not necessary for bushing ID for M5 bolts:

Installed a SpeedoDRD and reset the speedometer - 16.5% correcting original factory &
17" wheel error.
SpeedoDRD installation:
Found the plug to connect to in front of the air filter where
the screwdriver is pointing. This was a good time to change
the air filter, too.

The screwdriver tip is touching the plug to unplug and plug the
SpeedoDRD into.

This is the original plug separated and the SpeedoDRD plugs plugged in. The SpeedoDRD
cable is in the left side of the photo. The speedometer plug is not easy to get to, but
did not have to remove the bottom half of the air filter or radiator to get to the plug.
Had to be patient.

This is the button on the SpeedoDRD to press when setting up the - or + % needed to
correct the speedometer.

Secured the sealed SpeedoDRD on the fuel tank sending unit cable so it's easy to get to.

This photo was taken 3/10/12 on the Devil's Whip, NC Rt. 80. Running PRII 120/70/17 & 150/70/17,
with Sonic Springs & PJ10W oil in the front forks. The sonic springs firmed up the front
suspension replacing the original springs. The SV650 front wheel conversion has been
working great.
