Didn't look to be.
Actually, Maurice didn't have a bike till he was twelve, it seems, and didn't come from a racing background at all. He spoke of the difficulty of getting into clubs in the late 60s/early 70s. He was a rider for VCL, as was Russell Williams a few years later, as it happens.
Maurice's son has got into racing in the last couple of years, and has ridden ten races, of which he has won four (the other six, he only came second). Jermaine Burton is a name to look out for, I suspect.
