Re torquey engines, it waa always fun the times I got to ride big 2 cylinder or big singles, just how neat it was with a low revving tons of torque engine.
I certainly was used to rowing a 6 spd gearbox, but clearly to me, having ridden motorcycles makes one very aware of gears and whatnot on bicycles because we're used to thinking and knowing what gear we are in always.
ps, I've always wanted to ride a Harley, but haven't had the chance. Have ridden big BMW 's a few times.
