Horse power? You can't be serious. Show me a Jap Bike that can turn in a 215 mph 1/4 mile run. Do you know why Harley was not around for the majority of the NHRA motorcycle racing? They were too large (displacement) the jap Bikes were averaging 160-185 1/4 mile speeds. Yes they have more HP but lower torque and smaller displacement. I have seen Harleys run 24 mph 1/4 mile @ 5400 rpm I have owned many motorcycles and as I said before I loved them all. Jap bikes are fun and quick, Harleys are fun and fast. There is a difference. Horse power vs torque, top end vs acceleration.
I knew a guy that ran top fuel and he told me he loved racing the Harleys. When the light turned green, they usually exploded...
Now, to be honest, when he said his bike was a “Kawasaki”, it was only loosely based on the design, but I’d be surprised if the V-Twins had any HD parts on them either.
