i 've read that roof of perisopic series one is lower, not all LP 400's,factory modified it after few carspeter_k said:Guys, go back and check out the C/T measure thread. I think the inside cockpit of a Series One is actually shorter. I've heard that the roof/rollbar/cage itself is lower. It's getting interesting.
i have personally seen lp 400 and 25th side by side in the museum and i think is true but i can't prove it
