My buddy had a 3 seater, mine is a 5D. We showed the mechanic how mine reved up 2000 rpm's going into 1,3,5,R, We were discussing with a mechanic that it possibly coud be differences in the two and the 5 seater clutching differently. For the record, I don't buy into that.
Here is a safety issue for the Honda Attorneys to think about: The 1st gear slippage caused shuttering in 1st gear, low, manual. My ramps were properly secure and the bike started shuttering and pushed the ramp from under the tire.
All is well, I had the bike in 4 lock, so I was able to drive it up the rest of the way thanks to my step bumper. I have since, built steel ramps that secure into fabricated channels on the back of the bed. This could have been a lot worse.
Lots of arguments can be made here and mods can be made to accommodate difficiencies but safety may become and issue at some point.
Someone mentioned sticking to facts back in the thread. I.e. driving experience, conditions etc, so feel free to ask away. I'm not mad at Honda. Contrary, I think they're the best.
Still love my P1K more than any other bike though.
