Which good brands are still producing a tyre with this dimension?
The front tyre is MM90-19. Is this obsolete numbering identical to 100/90-19?
The tubes for both tyres are originally having a rubber valve stem.
Apart from at V-twin mfg, I cannot find these anywhere and would prefer a
good brand for the tubes. Anyone who knows where to find this?
Are the rubber stem tubes better or worse than the metal ones or does
this depend only on the type of rim you use? Thanks in advance, Hans.
