i am just wondering if these are worth the money, i have a 2004 honda crf450r and i do a little bit of racing, but most of the time i just ride some private tracks and some trail riding and playing around at the local sand pit, i just got this bike and dont know a lot about 450's yet, my last bike was a 2005 yamaha yz250f and this bike was great but i had to sell it for financial reasons 2 years ago, any input would be great
