Wolff revealed he was unaware Hamilton was testing a Yamaha R4 on December 1st at the Jerez de la Frontera circuit alongside Michael Van de Mark and Alex Lowes, both IWATA centaur Superbike instructors.
The Englishman was enthusiastic following the tests and admitted to loving two wheels more than two.
Speaking to La Gazzetta Dello Sport Wolff said on the matter: “When the news spread, I tried to call him, in vain.
“So I called one of the three engineers who was with him. "Where are you?". "Er, um, we're on a track." "Are you turning all three on the motorbike, then?" "Yes, but ... we're done ".”
Hamilton did, however, suffer a small accident during the session after turning seven seconds after the official drivers and Van der Mark felt he showed a bit of recklessness.
Despite this Wolff joked about the whole thing: “We all had a liberating laugh.
“But it is clear that for Christmas I will not give him a bike!”
