Limp Mode causes the trike to have a RPM limit of I think if I am rmrmbering right 3700 and it immediatly goes to that RPM regardless of where or how you may be riding. Even on the highway where I was with no one around me it is earth shaking to say the least. I sure think it is a safety hazard that can as noted above kill a person! What can be done about it? Not much I would guess as it is just another case of Big Brother is watching over you! Bill PS That other post is spam to what I see of relavancy to the post?
