Newt are you talking all V-twins? I will tell you my air cooled Victory will run a whole lot more than 90 all day and not burn my leg. It does 90 in 3rd gear. I have spent money on tires, oil and brakes. JD Power rated it one of the best motorcycle motors in the world.
Now, my Triumph has killed two CDI units, two coils, rattled the chain guard to oblivion and warped a front rotor. The stock suspension was nothing short of garbage.
The Honda V-twins with liquid are about as trouble free as anyone could ask for.
If you don't like V-twins which is very clear, that is OK>
Every V-twin is not a Harley early generation block head. There are lots of flavors of V motors. They are not all created equal.
