So, in our new park we are next to a bunch of suthern boys, great guys, even better cooks. But they do give me a hard time about my "lawnmower". Does harley make anything stock that can outperform a new 600? both on the strip and in the hills?
HD's got nothing in there lineup that would still be in front of your F4 after 30mph. Their big bore cruisers and the V-rod have a load of torque and jump off the line pretty well, but you'll be passing them before you get to 5k rpm.
I have an 82 yamaha XJ650 (maxim, not seca) that will get up and run with or in front of any stock Harley with the exception of the V-rod and the previously mentioned Destroyer.
A new 600 is no contest. An R bike is almost comical.
