America / Speedy with a Big Bore is.....Magnificent and out run/haul only the most tricked out HD....or at least that is my experience



I don't think the big bore will get you into the 12s for 1/4 mile times. Stage 2 on that HD will get it to 12.5 or so. Its a size, stroke = torque thing.

The 1200 Sportsters are already just over 13.0 out of the showroom. We are in the mid to high 14s stock.

That bike is why they built the T-bird.
