My guess: spur shaft has a gear on it, turns another gear on the 'main' layshaft with 2 pulleys on it.
But that's complicated. Belt/Pulley main reduction with a pulley-ish spur and pinion would be the other option... Don't know if that actually works though, I can't see how you'd get sufficient belt wrap on small 'pinion' pulleys.

Kyosho tested a prototype Lazer with this style transmission several years ago - before the ZX5 was released.
