Yamaha R3 Undercut Transmission 2015/Current

Description

The Yamaha R3 undercut transmission will keep you in the game and not worrying about why the bike drops gears when it wants to.

As a lot of the current racers and a few of the new racers know that the little bikes do have issues with their transmission popping out of gear, these motorcycles are built as a commuter low budget bike that we, you want to take to the next level.

Being on the race track is a lot of fun and at the same time serious business, this is a common complaint we get at Spears Racing”I am in the top end of 5th gear and fully pegged on the throttle,all of a sudden it goes into 4th gear or a false neutral” Yes very common and this is why we have transmissions on the shelf for the fast exchange program  

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.
