Fred Launchbury rode the Todd BSA Bantam but only finished once in 20th.

Ariel Arrows started in 18 Lightweight races only three ever finished.

Mike O'Rourke 7th 1960
J.G Horne 16th 1961
Albert Moule 16th 1963

O'Rourkes performance was brilliant he was only beaten by by six works machines.

Hocking MV
Ubbiali MV
Provini Morini
and three works Honda's

Just shows how good the Arrow could be if you could keep it going. Don't forget those 250 races were six laps not like the Micky Mouse three and four lappers of today and O'Rourke averaged over 80 mph 45 years ago.

Hocking and Ubbiali did a race average of nearly 94 MPH.and the course was nothing like it is today
