xc -Cross country (basically woods, trail riding)
mx - Motocross (basically racing)

 

xc it hairscrambles through the wood's.mx is on a track with alot more jump's.

 

K I thought so but wasn't sure I need two front tires making sure which ones to see about. Going to post in wanted for a used set f xc something extremely cheap

 

ok now let me confuse you some more.......if you have stock arm's and want to race xc i would go with some 4.1's.they make you wider,BUT it will give you mare bumpsteer.as for kind of tire's,razor's are a good alaroung tire.

 

I think you have it backwards. +3+2 will make you wider since the 3" is to the inside and 2" is to the outside. +4+1 is narrower by following the same measurements.
I have two sets of hiper fronts (+4+1 and +3+2). I have +3+1 long travel arms and I also ride XC. This is the reason why I'm selling my +3+2s.

Adavis, check atvmaniacstore. I picked up my whole set (22" front/20" rear) of GBC XC Masters for $263 shipped. That was the cheapest I could find until I saw that sam's club online had them for about $220 shipped. I just don't have that membership. Basically the Masters are the same as the X-Rex, just changed name due to legality reasons (what I've heard).

Anyways, here's a post explaining the offsets. Even though it's about a different quad, it helps explain it better than I can. Opel has it right about bumpsteer and all of that. There are advantages and disadvantages in going with different offsets, as per anything you choose. http://www.atvriders.com/articles/atvwheeloffset.html

 

For XC don't rule out GNCC. You see that acronym thrown around a lot while relating to XC. I'm still trying to fully understand what the full difference is between them but I'm slowly picking up on it. Somewhere I've read that harescrambles are XC but at a dead engine and where you have to run to your quad and start it. I could be wrong.

Please someone spread a little light on this matter. Meanings of different types of racing:

XC
GNCC
Hare Scramble
Supermoto
MX
FMX
etc.

I know what some of these mean but for GP, it'll be nice for someone to spread their knowledge so others will know as well. I just don't want to lead someone on the wrong path if I don't know 100%.
