Derek Minter, Senior 1960. First ever 100mph lap by a single cylinder machine, 22-24.2, 101.05.
The fastest anyone has managed since on a similar machine being Bob Heath in The Classic Manx at 21-12.5, 106.74, 1997.
No disrespect to Bob (fantastic lap), but 5.69mph doesn`t seem to be much of an improvement over 43 years considering the improvements that have been made over the years to: tyres, engine developement & the circuit is like a billiard table now, compared to 1960.
The best ever video, on board lap has to be Shaun Harris`s lap on this years TT review. So precise and fast, great commentary too! Well worth a look.
