Sizing It Up: Is a Bigger Motorcycle Better?
|
This dyno sheet tells only part of the story of how large and small displacement bikes make their power. The Vulcan 1500 FI gets its bottom end grunt from the big slugs in the cylinder, but those pistons also limit maximum engine speed. The 500, on the other hand, has to be revved to make power. Compare the 500's 5250 rpm peak torque with that of the 2750 peak of the 1500. Keep the little Vulcan's rpm above 5000 rpm for maximum scoot. The Classic works just fine at any speed above 2000 rpm. If the 1500's making so much torque down low, why does the 500 whip it off the line? With smaller pistons, the engine can rev quicker to get into the meat of the power band--and there's the 250 pounds of excess weight the 1500 carries. View Related Article
