My old SX-650 had " double leading shoes " big ones . One night I was cruising about 70 on a two lane Florida road (dark night). Ya know how most roads have a big yellow and black where a road "T's" into another one --- well the road I was on didn't have one. So , I'm ridding double , overnight camping gear on the rear rack , and hit both brakes as hard as I could.
(and girl-friend starts screaming).
We got stopped just short of the ditch on the cross-road , but it's a good thing nothing was coming on the " T " road.
But there was no locking up of either wheel , by time we got slow enough for them to lock they were too " HOT " to be powerful.
