On a positive note---I at 73, DAV/stroke, may someday have trouble walking----but not at this point, solo scooter ok, even to put on lift alone.
Rather than put/waste $6000 plus on trike kit, why not try sidecar----Texas Sidecar has done SilverWing hookups @around $3500. Somebody in western Canada makes proper steering dampener, I think.-----now difference between sidecar outfit (I drove them for 40 yrs) and trike good set of driving skills required for sidecar---trike appears to me...just plop on and hope inside wheel stays down. I have near 75,000 mile trike experience----2 Messerschmits in the 50's...so know inside wheel in air.----once bike is converted right to sidecar use,not much good solo---I don't know if anybody makes different trail fork tree(maybe trike maker should), fork springs available, lower final drive gearing??smaller OD rear tire might work----and now for the car tire nuts, perfect chance to put car tires on as normal sidecar outfits don't lean----car bead and mc bead mix scares me a bit with side forces. I expect drive belts to be eaten up in sidecar use---about 20 years ago German magazine did Helix/sidecar test...they ride them hard---4,000km belt life.
Last I feel sidecar outfit behaves better on ruff roads...and of course fun, like "flying the sidecar wheel"
Last point---I think with unbraked sidecar wheel, stock ABS might work.....don't think that is case with trike.
