Clutch Basket, Clutch Friction Plates, Steel Plates, Clutch Springs
MDR Clutch Basket
supplied with screws and rivets
Well we could say that it saves weight, which is true, but the honest answer is that it makes them easier to to produce and so reduces the price. There is simply no need for full depth splines. If a kickstart gear is going to spin, it must shear the splines at the root. This will happen regardless of how deep the spline is. Remember that this gear is only used by the Kickstarter. Obviously it is vital that these splines are strong enough to withstand the kickstart pressure. Would they be stronger if they were deeper ? No they would not. The strength of the splines in shear is dependent only on their width, not on their depth. Our splines are 0.5mm deep. O.E. splines are about 3mm deep. If they were 10mm deep, it wouldn't make them any stronger !
The splines on these baskets, being made from 7075 alloy, will withstand more than twice the kickstart force of O.E. ones !
This diagram illustrates how the forces act on the kickstart gear splines.

As you can see, the depth of the clutch basket spline has no effect on its ability to resist the force of the kickstart gear.
Clutch Friction Plates
Can be used with OE Stock Baskets, inner hubs & pressure plates.
Developed and recommended to enhance the performance of your clutch basket.
Provides optimum hook-up with minimal heat build up.
Exceptional production tolerances & flatness.
All fiber plates use organic non-abrasive materials to avoid damage to the rest of the motor as plate materials break down and are circulated throughout the motor.
Manufactured to OE specs using hi-spec materials.
A high quality replacement and a lot cheaper than the genuine.
