DF25E

Suzuki’s V-Twin DF25E is loaded with high-tech features, like an onboard computer that monitors engine temperature and rpm and instantly sets ignition timing for peak performance. And a new ignition system that’s lighter and sparks hotter, making pull starts easy. Suzuki 70-defree twin cylinder aluminum block maximizes power while reducing vibrations – without a heavy counter balance. These light-weight design features and a sturdy handle makes it easier to carry.
