Hi, Dianna...I'm not sure from your post, but it appears that you're already sidehacking with a VN750 as the power unit. I'd be interested in knowing what type of sidecar you're using with the VN750 and whether you've located a custom mounting kit for the bike. I know of one company, Texas Sidecar, that carries a custom mounting kit for the VN750.
With regard to the $10K price Eggnog is citing, probably depends on where you're located. Here in Sacramento, CA, the closest URAL dealer is in Modesto, about 90 miles away. Price for the 2007 Patrol 2WD is $10,299 and for the Tourist (1WD), the least expensive of the URAL sidecar rigs, is $9295. The most expensive URAL rig is the military-style Gear Up, which is listed at $11,295...
Would sure like to know if anyone else here is running a sidecar rig using the VN750 as the power unit...anyone??
