A Direct Power Transfer in 6th Gear = Quiet and Efficient: With a direct drive system, there are less gears making connection when cruising in 6th gear. Power essentially comes in from the motor and straight out again to your back wheel. This is the gear the most time is spent in for highway riders, so it makes sense to optimize the power flow for this gear.

Power isn't lost by turning additional sets of gears through the gearbox and transmission fluid like conventional drive systems. In additional, that conventional method of power transfer projects unwanted gear noise too.

Helical 4th, 5th, and 6th Gears = Smooth and Quiet: A helical, or twisted, gear tooth form allows the gears to roll and slice into each other for a graceful gear connection. This design grants the smoothest feel and a quietest execution. The conventional slapping together of gears is noisier and vibrates more, but it handles more torque. That is why 1st, 2nd, and 3rd gears are still conventionally straight-cut. These are the gears that you typically rip though to get to the higher gears bear the most torque from take-off. At a certain amount of pressure, like unscrewing a bolt, helical gears put later pressure against your bearings, thus straining them. Using our dedicated drivetrain wisdom, we balance the use helical gears and straight-cut gears for optimum performance.
