I agree, I rode my buddies modded shee, piped, jetted, airbox lid punched full a holes, ect... it goes alot faster than you can take it offroad... but so do both of my 4 strokes... on the street you can see where bikes top out easier. or in dunes and such. to me that is more the type of riding where a shee shines. in twists, jumps or any real offroad stuff, it seemed like it was suspension limited... so any bike with plenty of power, that's usually the 1st place to start building.. but it's expensive so I didn't do anything on any of my bikes lmfao bought them as they sit suspension wise...
