Spears Racing has decided to specialize in the lightweight transmissions with what we call the “Race Cut” this is essentially our way of doing the process of undercutting Transmissions( in the engagement direction only)

Once the undercutting process has been achieved, we then begin to work within the particular application to complete by blasting all of the transmission gears to maximize the surface area for cleanliness and inspect that the gears spacers, washers are ready to assemble back onto the shafts.

Undercutting is one of the most highly regarded modifications for race motorcycles. Many manufacturers do not undercut their transmissions at the factory. Undercutting involves the modification of the drive dogs and slotting to precise angles. Creating an interlock of the gears under acceleration, virtually eliminating the occurrence of an involuntary gear jump. Most drive dogs from the factory posses a 0 degree back cut, producing rounded gear corners under normal wear, in turn creating involuntary disengagement. Mach Modified under-cutting service can precision cut your transmission to perform at its most accurate and true level of performance.
