Does not look comfortable.
Tank bag will make the long ride in higher speed comfortable
Like down here, north Italy, just from Austria.
A friend sitting behind me sat as a king with arm rests.
No problem to ride >1000km/day on German autobahn.
Did 1850km without sleep when going back home. Started from Kitsbuhel, Austria the last distance.
Only rest (except gas refill with coffee/food) was a few hours on the ferry Germany-Denmark, 200 km ride and another ferry, 30 minutes max.
Badly crimped wires to coils started to show then. It healed after 30 minutes...
Mostly over 160kmh all the way after we left Austria.
Even faster in Sweden in the early morning keeping the sleep away.
Micro sleep happened ... My friend helped me to stay awake .. knocking my back .
My today blue K6, avatar bike. Then with 836cc.
