We’ve been making transmission pulleys for years, both aluminum and steel. In short, the teeth on the aluminum pulleys never hold up with miles. Deformed aluminum pulley teeth will lead to saggy belts. Saggy belts and saggy tits are not a good look. For a bike that gets ridden, steel is the only way to go as it relates to the belt running hard against the front and rear pulley teeth.
Steel is also the material of choice for the clutch basket. When a bike is launched hard, the clutch plates aggressively spank the reciprocal flanks on the clutch basket. Deformed aluminum flanks will lead to increased clutch rattle noise, grabby clutch engagement, and hard shifting 1.54 pulley ratio with a 28 tooth pulley on front and a 43 in the rear for a 7% increase in torque to the rear wheel on stock Softails from 1990-2006.
The Synchronous Belt Drive for Softail provided added support to your transmission main shaft too! More so than any available design in the market, the inner clutch hub reaches farther on the mainshaft towards the pulley nut. This reduces flex and stress on the mainshaft.
Motor plate and edge guard are made of 6061-T6 plate stock. Pulley caps and dog bone are made of 6061-T6 forgings.
10 plate clutch
2.4” wide belt 14mm large tooth belt for extra bite
Available with or without the outside bearing support (dog bone), however the dog bone configuration is highly recommended for those with Tourette’s Syndrome in the right hand.
Available in show polished or black anodized finishes
Anti-rattle hardware designed for silent operation when stopped idling with the clutch disengaged.
Available with 0" (zero) or 1/2" offset configurations.
I bet you're wondering what the hell "Synchronous" means in BAKER's dictionary.The answer is simple. Our pulley interface with the belt has full contact in the valleys and spurs. The result is the quietest belt drive available according to the tests. In addition, obviously, wear is minimized compared to all the other belt drives that make contact with the leading edge.
