Depends how far back you have the chain adjusters on your swing arm.

The 50 will add 5/8" to the circumference of the sprocket. Since the chain runs over roughly half of that, that means there is 5/16" more chain contact. Since this is divided between the upper and lower runs of chain, that means the axle will need to move forward 5/32", or about 4mm.

I don't see a problem, do you?

I run the woods map in my 2011, definitely helps. I also turned up the idle just a fraction. Even with this map you still have to ride the thing on the throttle, not surprising really considering it is a YZ. I like to ride like that anyway so no problems. If you wanted a civilised woods/trail bike the WR would have been ideal.

My gearing 13 x 51 , gives it a bit more snap out of corners.
