I was talking to Pete at Side Effects and he is going to have a kit for the Burgman trike ready for next spring. It is called Leading Legs which you can see on the web site on the Yamaha Royal Star. He does a lot of work for the GW trikes and everyone likes his products. I will be getting the first one to test and give him feed back. He does not make them for the Voyager kits for bigger bikes because of the back wheel lifting in turns, and it may act as a bike rather than a trike, but may make them for Voyager on a Burgman .  Wayne
