S&S Cycle 910-0205 97" Big Bore Kit Black Twin Cam

The S&S Cycle 910-0205 is a 97" big bore kit in black for Twin Cam engines, designed to add displacement and performance while keeping the factory look. Often searched as a big bore cylinder kit, it increases the bore size from 3.750" to 3.927".

Key Features:

• More displacement and performance: the larger bore increases engine displacement.
• Better heat dissipation: increased fin area helps the cylinders shed heat.
• Larger bore: bore size goes from 3.750" to 3.927".
• Easy installation: no machining or rebalancing required.
• Close to stock appearance: 11 fins and a full fin pattern on the cam side closely resemble the OEM shape.
• Subtle branding: the S&S logo and part numbers are less conspicuous, for a better overall appearance.

A practical way to gain displacement on a Twin Cam without a noticeably different look from stock cylinders.
