Title: How to fix torque problem with front forks
Post by: Who42 on August 07, 2009, 05:46:17 PM

Here is a torque arm that I designed its a one peace metal stamping that takes the place of one or two inner spacer washes using a metal hose clamp to secure the lever end to the lower front fork. Torque arm is required on light alloy forks and frames due to the low yield strength of the material is unable to withstand the motor torque without bending and eventually breaking or bending the axle slots  ;D
