Gentlemen, I have been wanting to get back into trail riding (it's been like 20 years!) and I recently bought a 2003 YZ450F for the amazing price of $2000. I know that it may not be the perfect trail bike but the price was right and since I'm 6'5" 240lbs I thought it was a good choice. I know this thing is a beast and geared for MX rather than trail. So my question is... could I or should I make a sprocket change to help me manage the bike? Would it be a bit safer or smarter to start out this way since I'm just getting back into this? I'm not planning on being a maniac out there, but I just wanted your expert opinions. Thanks!
