Hi Hennie,

Road speed depends on several factors, the fixed gear ratios being only
one.  The others are the rpm you're comfortable turning the engine, the
rolling radius of your tires, the quality of the road you're bouncing
over, and your estimate of the stopping power of your service brakes :-)
I run small tires and estimate my brakes conservatively (although they are
much improved with new drums) so I rarely run above 80 km/hr.  With larger
tires some of us run 100 km/hr.

I don't have the gearbox ratios to hand, but the axles should be 4.70's.
