APE TOOL STEEL SHIFT SHAFTS

APE has designed a tool-steel shift shaft. We initially designed these shift shafts for use in Hayabusa powered Radical road racing cars. These cars weigh more than twice as much as a motorcycle and put tremendous stresses on the transmissions with constant up shifting and down shifting.

The problem..... Both the oem and currently available high performance shift shafts were bending and flexing which wallows out and oblongs the shift shaft holes in the cases which eventually scraps the cases.

The solution...... It is well known that APE builds the strongest, no flex, tool steel wrist pins in the industry. The very same pins that Spiderman McBride uses to run those five second ETs. So why not use this expertise to build a no flex shift shaft. And that is just what we have done. Tool steel shift shafts, just like McBride's wrist pins, now available for your Hayabusa.

SUPER DUTY HAYABUSA TRANSMISSION OUTPUT SHAFT

One area that has been found to be a weak point in modified Hayabusas is the stock transmission output shaft. Under extreme loads the stock shaft can break resulting in engine case damage. The Super Duty output shaft from APE is machined from super high strength aircraft alloy steel. The vulnerable sprocket spline area has been enlarged from 25 mm to 30 mm and takes the output sprockets listed below.

This shaft is a complete bolt in with no modifications necessary.

BILLET SHIFT FORKS

Made from 4140 Chromoly Steel, Heat-treated and micro polished.
These forks will spring back close to the original position if you must chop the throttle, wheelie, spin the tire, leave gas valve in the off position, or have any other emergency with an automatic transmission. The main advantage being that you would not have to change a shift fork between rounds and possibly miss a round OR a chance to Win.
Don't spend all the money to drive to a race and miss out on winning because you don't have time to change a compromised fork between rounds.
