Reach out to the Victory dealership in Murrell's Intel, SC. They have a website called "HotVic" and have probably done more variations on rakes on XC/Visions than anyone else out there. At the last MB rally, I counted 4 different approaches to raked front ends. look them up online and see what they have to offer.
As far as front wheels go...
21" can be done on these X-bikes without ANY rake at all. However, 23" wheels do look better but required a minor rake. If your going to invest in rake then you might as well go with a 26" wheel which looks the best IMHO after seeing SO many of them during last years rally. Some have gone to the 30" wheel but IMHO it looks "too big" and kinda makes it look like the bike version of the too-big-a-rim BMW sedans that ride around jack up in the air like a 4x4...
While all rims are expensive, the 30" rims are running $3,500 and up so it starts to become cost-prohibitive when you are spending $7K to put a front end and new tire/wheel combo on a bike. In contrast I have seen some SUPER NICE 26" front ends that guys spent less than $5K on (and one guy welded his own to bring it down under $3K)!
It's not just any victory.... It's MY Victory!
