Not everyone needs an expensive touring bike. You can use any bike for touring.
When I was staioned in Japan I took leave and rode a Nishinki road bike. This was back in the eighties when people weren’t taking off on bikes to see the country or the world.
I remember going from Knob Noster to Warrensburg on a bike in the eighties and people thought I was crazy. Also dodging flying objects. Back then a person stopped riding bikes in high school. Go get a car.
Today plannning a bike tour is easy. Some people hop on the bike they got and go for. Some people stress over what bike. Some people pay big dollars for their bike.
Why spend big money if it is your first tour. You may go and survive and decide no more long tours. Maybe just overnight tours or commuting or just riding around town is enough.
If you love touring and can’t wait for the next adventure maybe a more touring exclusive bike and paying more may be worth it.
Just ride and enjoy the adventure.
