I gave an aluminum hitch rack and a 188 lb Honda Trail 90 that I carry on our 27 foot Tioga Class C. A can feel some difference in steering action but no serious affects. I think that cruiser weight bike would put too much load on the hitch and bumper and make steering too light. Also with bike in place, can't open rear cargo bay door. I have tried front mount carrying with same weight trail bike and didn't like lack of access to motor and damage to hood paint from hooks on steadying straps. If you have to take a cruiser with you, a covered trailer with anti-theft locks sounds like the best bet for a mid-sized Class C. It'll keep your bike clean and safer and carry extra "stuff"
