 M3-Mad Monkey Motorsports Race Swing Arm Isolators.


This is for the elite.  1/2 inch drop in your pivot shaft.  Resulting in 1/2 of clearance at the frame for rocker box clearance.  But at teh same time correcting the positive pivot shaft height.  


This is a completely new design that is ONLY available from M3 directly.  This is NOT the same race isolator from the past.  We have found more information during this season testing with our bikes and customers bikes.  Better 60 foot numbers, less wheelies, and more traction.  There is NOT a part like this on the market.  The photo is not of the part as we want to keep this information for only the racers that want the best and that extra edge on the competion in 2021


We have completely changed the gemoetry AGAIN.  ALl becasue you racers deserve the best. We will keep this design in house to see when we are copied.  There is a Patent pending for geomtry only.  


The M3 Isolators remove unwanted chassis and swing arm flex. Great upgrade to replace worn or stock rubber swing arm pivot isolators. For use with or without a spherical bearing kit for the ultimate in rear swing arm control.


We were first introduced to the design when we were racing Buells in the late 1990s. They were provided by Don Tilley owner of Tilleys Harley Davidson. At that time is was a race only used part. Since working on newer FLH performance bikes we saw the need for them to be used there also. There are many variations of this part that has been made for over 30 years. This is the M3 take on them.


Most of the FLHs  being built now are purpose built. This will drastically improve handling.
