I wouldn't worry about your weight being a problem with the SV650. I only had mine for a short time, but I did get the opportunity to ride one day with my son when we switched back and forth between the SV650 ,and my DL1000 V Strom. I out weigh my son by about 40 lbs, that puts him at 200. From 0 to 100 the two bikes were about as close as two bikes can be, and it didn't make any difference who was on what bike. In the twisties the 650 could always pull away from the V Strom, even with me on the 650, and he is a better rider than I am.
