14/47 is stock gearing and I still have some unexpected lifts! Can't imagine what a 50 would be like but I'm an off-road guy.

Depending on your weight. I can't run stock gearing. Am down to a 44 rear. I think a 43 would be perfect for me in the desert. First dropped to a 45 and it made the bike so much more controllable for me. Front wheel stays on the ground most of the time. I am about 165 or less with gear. Have 14/45 on my AF thats close to being finished. Planning to use it mostly for the MX track though. Hope to do 2nd gear starts and hang with the 450's. :roll:

You need a wider rear tire.

This is 14/47 in a desert wash a few days after this rare thing in Las Vegas called rain. No matter how much I try to stay off the gas and still move forward without traction loss it was still difficult. You can hear the engine start to work under load and then loss of traction and the engine says I won! It sounds like you're a track rider but I still can't imagine a 50 on the back even for motocross!
