After looking at their website, I would agree... Looks like a quality kit at a reasonable price... Unfortunately, they do not manufacture anything for a Goldwing or any other manufacturer other than HD and 2 different Yamahas as far as I can see... So the Frankenstein doesn't really enter into my equation... Even so, they are about twice the price of a Tow Pac, although they fall into the true trike conversion area...
Goldwing owners are limited to kits like Motor Trike, Hannigan, Lehman, Roadsmith, California Side Car, Champion, DFT, and perhaps a few others... Most of these kits start in the 8000 dollar area... Then add paint for another 1000, floorboards for another 1200, reverse brake at 400, aux fuel tank at 5-700, special anti sway suspension 1200, independent suspension add another 1000-1200 and then finally add 1200-2000 for labor... So it doesn't take long to get up into the 15,000-20,000 price range...
And finally, most of the above manufacturers do NOT retain the ABS and linked brake feature of the Goldwing, which to me is a complete show stopper... I believe Motor Trike and Hannigan do but I think that's about all who do...
Frankenstein products look good but the Wing is shaft drive and offers different challenges to trike builders... I'm glad you are satisfied with the Frankenstein kit but unfortunately it does not apply to the Goldwing... I was out riding on the TP again this morning and for the money spent, it does a really good job, especially with the 4.5 degree rake kit... Setup is all important on outriggers and I have mine dialed in to precisely satisfy my style of riding and that certainly makes a difference as well...
I never have claimed that any outrigger kit is superior to a real trike conversion, but I have consistently said that for the price/performance differential, they are a viable alternative...
Ya pays yer money and ya takes yer choice!!!
