Your right Ian virtually every commentator complained about not being about to see the numbers not only the front but the side numbers because of the angle of the bikes.

We also have a variety if different coloured and styles of numbers in the same class.

The ACU always isued standard oval numbers with matt backgounds for the TT with each class being different, 124s Black 250s Green 350s Blue 500s Yellow Production Red and 750s/1000s white. riders also had tp have maching cploured numbers on the backs of their leathers as well.

The background and number colours for classes were used universally all of standard fixed fixed dimensions to comply with FIM regulations.

Some of the ridiculous numbers today are almost impossible to read when they are stood still never mind when they are moving.

When were the regulations changed..
