There is no new gears. What they do is regrind the dog gears with 4-6 degree angle rather than 'em being straight and slipping at first bit of wear.
Below are photos of the gears before the fix.

As you can see the dog gears are rounded on 2nd gear and they are very flat on the rest.
They should have never built a gearing like this on a bike with this much torque.
