Balz Renggli of Moto Forza in Escondido, California, provided us with a rare 1992 Ducati 888 SP4S, the model Doug Polen won the 1991 and ’92 World Superbike championships on. After the first two corners of Chuckwalla’s fun layout, we knew why. The power is right there, right now, and the brake feel is outstanding. Just as we started to really hustle the bike, the worn Bridgestones let us know the limits were quite low. I pushed the front pretty good and Spencer tucked it completely, showing me the scuff on the knees of his leathers. “Even with the carbon tank, this bike feels pretty tall and really loads the front, so having that old tire on the front is probably the worst combination,” Spencer commented. With better front grip, this Duc would have been a joy on the racetrack.
