SPUR GEAR DRIVE Motor Mounts can run using Helical or Straight-cut pulleys.
Helical Motor Pulleys give a gear ratio of 1:5.8 when paired with the 58 tooth Helical Slave Pulley. The Helical shape allows for more surface contact between the Slave & Motor Pulley Teeth, creating a quiet & efficient drive.
Straight-cut Motor pulleys pair with a 59 tooth Slave Pulley, giving a ratio of 1:5.9 – meaning there will be a tad more power when accelerating in comparison to the Helicals. However, due to less surface-contact between the gears, Straight-cuts are much louder when riding along (although we’ve found some mad people who like/prefer the noise!).
Made using Hardened Steel.
