I've read and read unsuccessfully trying to determine how much trail is needed for a (rear eng VW) trike. I've read that as little as 2 inches is correct. Is less trail required for a trike (any) than for a two-wheeler? If so why?
I have access to a good rake and trail calculator and know how to adjust frame rake, offset, triple tree rake, etc to change the trail but I just don't know what trail I should be adjusting for.
