Big Denny, the trike kit decision is going to be a "what you like and what you believe suits you the best." All of us have our own preference. Me?....Well I love the MotorTrike kit on my GoldWing, and this is my third one. My husband has MotorTrike on his Harley Ultra... BUT he had a Lehman conversion on the previous three Ultras. As for weight...my Tommy is also a 300++ guy and he has not had any problems. We have ridden our trikes to Alaska, (twice, once all the way to the Artic Circle), twice to Nova Scotia and Newfoundland, and we've been to almost all of the lower 48 states. When we travel we look like two gypsies going down the highway. Besides his own weight, he usually has at least 50-75 pounds of luggage loaded on his trike. We have talked to a lot of "heavy weight" Trikers who ride other conversions and it seems the story is the same...they don't have any problems either. Again, I believe it will be what you think looks and feels good for you. If you have the chance, then you should test ride as many different conversions as possible. That's my two-cents...may not be the answers you were looking for, but I hope you have fun looking for what suits you best, Ride Safe!!
