I can get a good deal on 07 RMZ 450 and i was wondering if i could make it a good trail bike for cheap. I tried the bike in open field and i can say it has awesome power and i like the handling, brakes and bike in general but i'm worried about 4 speed gearbox for trails. Its not that tight all the time but sometimes we come to places where you must ride really slow and i'm worried about long 1st gear but on the other side it has the best bottom end power of all the 4 stroke bikes i rode so it might be a good combination. Bike is in really great shape, has all new on it and it is really awesome bike that i would really like to buy. I would like an opinion from someone who rides it. Is there a way to put a wide ration tranny in there?
