To make sure that the engine behaves itself at ultralow rpm, the gear-driven counterbalancer has been upped in mass substantially to net a 25-percent increase in the engine’s flywheel effect. Relative to the basic Vulcan 1500 from whence it sprang, the Classic has taller ratios for the top three transmission gears. For the ’97 model year, all 1500s will adopt the Classic’s gearing. Besides the functional changes, the Classic’s engine has also been extensively restyled. It’s now basic black, with recontoured chromed outer covers and polished cylinder finning. The new cylinder heads have a much more traditional proportion too.
