I just bought a used 450 and I use it for woods riding and need to change the gearing on it cause its way to tall right now. I ride the hills in south KY all woods trails firetrails and some rocky sections and thats where the problems are its a pain in the *** to have to hit those rocks with a little speed instead of just letting the bike lug over them in first gear. I dont know what the stock gearing on these things is front I think the front sproket has been changed. I also need to get some good belly and swingarm armor any good suggestions? Also is there anything else to worry about with these bikes this is my first sport quad after riding my prarie for the last 2 years so this thing is blowing my mind away with the kick *** power and handling. I dont need any more power till I get used to this thing in stock form.

 

The stock gearing is 14/38.

 

Either go down 1 tooth in the front or go up 1 tooth in the rear....this should stop the lugging and help you crawl better although I don't think the 450 was meant to crawl...it was meant to whoop some a$$.
