'OL Zuke 4 out of top 10 at Red Bud M1

Most of the recent "advances" in other bikes don't really seem to make the bikes better. That RMZ 450 is still a pretty solid baseline.

Because motocross is 90% rider. Remember the short red headed kid from Florida that rode green, red and then yellow bikes. He did pretty well on all of them. If your fast, your fast. If your wild and out of control, a bike won't change that. If your really fast but inconsistent, different bike won't change it. And lastly, if your a head case known for crashing, well, that's just what you do. Change bikes all ya want, the rider is still the determining factor every time.

I KEEPD SAYING TO YOU GUY OVER AGEN THAT SUSZUKI MAKE THE FASTIST BIKES

Because there are not bikes off the showroom floor...common sense isnt it?

What are the differences aside from suspension?

Fucked if I know, I dont work for the Suzuki race teams, I was replying to the OP... (in reference to his slow and heavy comment)

I think it's mainly because Dungey, Anderson, Canard, Seely are out.

Factory race motors.
Titainium and other light weight parts.
Geometry changes.
Factory suspdnsion.
Great testing program.
Great riders.
Buckets of money.

Yeh I noticed all the Suzooks up there.

Anyway ..... who in this world races a 'showroom' stock bike ...... NO ONE!
