I'm hoping it dont twist like a pretzel... lol The frame I have is all aluminum and so are the a-arms and steering stem. I can pick up the bare frame with one hand and place it over my head . It has been used for 300ft drags and never had a problem. But it has never seen some mean whoops on sand so I'm hoping it can take the abuse. But my rolling chassis weighed in at 83 lbs. That was with dirt tires and spindles on the front. So i figure my spindle mounts will drop around 10 lbs off of that. So unless the motor, carbs, pipes and chain weigh over 130 lbs i'll be under 200.
