New to this forum and Spyder. Recently upgraded from 2005 Harley Road King with Champion IRS rear end to 2015 RT SE6 with ISCI hand brake. Hand brake was installed by local, reputable Spyder dealer with top Spyder mechanic in our area. Rode standard RT (foot brake only) once, have incomplete paralysis in leg so very difficult to use. After less than 100 miles have the distinct impression that stopping distance on RT is farther than prior trike even when I use full force on hand brake. Could be that I'm decelerating more (i.e. initiating stop from higher speed?) but expected the RT with ABS to have significantly shorter stopping distance than previous trike. Wondering if the ISCI hand lever activating the foot lever is part of the issue? Assumed "or" operation of hand and foot brake but understand from sales guy the ISCI brake is serial?
