Time or mileage for timing belt renewal

When I bought my Eunos 1.6 it had, had the timing belt, v belts, water pump, o ring and head cover gasket changed in December 2014 at 130164km.  It’s now only done 12000km (7456 miles) since then and as I’m not detecting any noise from the water pump I’m tempted to leave things be as I understand the change should be around 60,000miles.  At the rate I’m driving this might not be for another five years or so; is there a problem with that?

No.
