54G Gear-Driven Cam

Gear drive uses less engine power to operate and improves valve timing accuracy over stock chain drive camshafts. Dynamometer comparisons show gains of 4 horsepower over chain drive camshafts.

• Can be installed on both carbureted and fuel injected models
• Sold as cams only, inner and outer gear kit and installation kit must be purchased separately.
• 12G: Similar timing to earlier stock 88 cams but gear drive cams are used instead of chain; No engine retuning necessary with this timing
• 21G: Bolt-in cam first introduced in 2000; More torque for all around riding with stock comp
• ratio and heavy bikes; Similar to #23 cam for EV80; (1700-5200rpm)
• 26G: Bolt-in cam for lower RPM torque, FLT, etc.; For two up touring, this cam will add torque and HP at lower and middle speed ranges; 1800-5500rpm
• 31G: Smooth idle, broad torque band; 2200-5800rpm
