What was Peter Hickman's 2023 outright TT lap-record average speed?

Peter Hickman’s 2023 outright TT lap-record average speed was 136.358 mph.

Hickman set the mark during the second Superstock TT race at the 2023 Isle of Man TT. Riding a BMW M1000RR for FHO Racing, he completed the 37.73-mile Mountain Course in 16 minutes 36.115 seconds. Because it was the fastest official race lap in any class, it became the outright course record as well as the Superstock record.

The speed is an average over the full lap, not the motorcycle’s top speed. The Mountain Course combines fast open roads, villages, jumps and tight corners, so the figure represents extraordinary pace maintained across a demanding public-road circuit.

Hickman had previously held the outright record from his 2018 Senior TT victory, when he averaged 135.452 mph. His 2023 performance therefore improved the benchmark by nearly one mile per hour. A common mistake is to substitute the three-lap race average, which was lower than the record-setting single-lap speed.
