For slow wheelies the 400ex is better I think, but at a fast pace the Z's front end is very light and well balanced. On the Z I averaged a 40mph wheely down a mile and a half road until it curved. The hardest part for a lond a$$ wheelie is leaning left or right so u don't float off the road do to curvature or light turns. The 400ex is fun for doing 1st gear wheelies for a very long distance picking up cans on the way!
