Help needed

Im asking a bit of a morbid favour but i will explain.

With my tattoist i am trying to design a memorial tattoo for deceased motorcycle racers, included in the design will be the logos that they were known for.

So far i have,

Sheenes No 7
Katohs No 74
The initals DJ (Dave Jefferies) which will somehow include a map of TT circuit
Joey Dunlops helmet design

I would appreciate if you guys could think of any others that could be included and if possible some pics of the actual logo they were known for.

I want to include Steve Hislop but am not sure if he had a logo, i only know of Hizzy ???

Any other general ideas about the whole design would be useful.

Thanks in advance.
