Hi guys we will be a bit ahead of you but we are travelling very slowly so may cross tracks yet ... hopefully!!
Great advice above, Insurance is mandatory in Mexico, cancel ANY insurance you have north of the Mexican border as the paper is useful for the toilet.
Mexico - Mandatory - $124 US min.
Belize - Mandatory - $15 US From memory
Guate - Optional - Nil
El Salvador - Optional - Nil
Honduras - Optional Nil
Nicaragua - Mandatory $12 US.
Same process every border, clock yourselves out then cancel your bike TVIP, cross to new country border, clock yourselves in first then clock in the moto and get a new TVIP, same every border, you will have to do varying amounts of unnecessary photo copying at each border, not much but they want it.
As noted above, kingpin of the situation is smile and keep your cool, have LOTS of water with you.
