I bought a Honda Forza 6 month old and 2000 km on the tachometer.
Unfortunately i forgot to check the service book. Now i noticed, that the
first service for 1000 km is not done.

In my home country, i know, if you fail the service for more then 200 km,
you lose the guaranty. But there was a rumour, that in Thailand it is not
so strict.

What is the reality? Any advice, what can i do?

Thank you for any helpful suggestion.

The best advice we can give you is to contact your dealer and make an 1000km service appointment, do not say that you're already past the 1000km on the meter...

It's very likely that they will do the service and you worried for nothing....

Thank you, this is what i thought first.

But in the service book is a line to wright down the current
mileage in kilometer.

But i think the best is to try and take my girlfriend with me
to explain. I doubt, that the repairmen at the garage will
understand me.

And for this one more question. Do i need an authorized
dealer for the service? Or is an ordinary garage okay?
