i do....in the woodsman class ;)
get 18's...its that simple. unless of course you cant and then 20's will do fine

You can do OK with 20s

[YFZ450Ridr]

what is the reasoning behind mx racers running 19s or 20s up front and 18s in the rear? to lower the ride height or be less bouncy with big tires?

[hardkoratvmxr]

one reason is to lower your CG and another is to make the ride height lower

also less spinning mass equals better performance

another is less sidewall flex

Or you can always go for the 19";)

18 and 19 for MX, 20 and up for everything else...I think.

18" best for mx. 19" best for sandy or rutted mx.
