yes it is the `Mk2 ridden by Dave Lecog
Clive Waye was trying to beat George Brown's (Nero) 1/4 mile record, only for Alf Hagon to dip into the nines, so he modified it into Mk2A (Above) with more boost, in 1969 went 9.815, then 9.68 in 1970.
In 1971 they took the world standing kilometer record with a 18.23 and the british 2 litre 1/4 mile record.
When Dave Lecog took over the driving (Riding) duties, he had the seat set higher for more control.
