!9" for MX and 18" for enduro.
More rubber in 18" and more traction, you can have less air pressure in it. Softer ride in the woods.

As others have said, there is no difference in the ride height between the wheels. If you run a Tubliss system, you won't have to worry about flats, and you can run a lower pressure.
Bushie,
How on earth do you get a 150 to fit, i have a 120 on mine and had to move the exhaust as it was getting hit, stock exhaust.
Sure a 150 would kill it, and also wouldn't the swing arm be too narrow ?
Obvious there is a way, how ?
