I need some feedback on gearing. I have a 500EXC which came with 15/45 gearing. First gear was about the same as my last Honda motocross bike, while sixth gear was so high you have to be going 65 mph, to shift into it an cruise at 80. I put on a 14 tooth countershaft and it really feels lower. First gear is low enough for must stuff so far, and 6th gear seems about right for 55 mph cruising without over- revving the motor in the highway between trails. My question is this: I keep reading that everyone with a 350/450/500 off road model is using either a 14/48, 13/48, or 14/50 combination. I can't see how 6th gear doesn't end up the same as a close ratio 5 speed with one of these combinations. Remember, I have NOT tried any of these, so I'm reaching out for some feedback?
