The Big-Speed automatic clutch system is especially developed to meet the high demands from our customers.

Since the engines become faster and stronger these days the clutch has to handle much power as never before.

With the Big-Speed system you get the best clutch system available on the market!

This new clutch has 4 shoes which can completely operate by your personal taste through adjusting the spring types.

You are now able to press 2 shoes earlier in the bell within the startup cycle by 700 to 2000 rpm.

When the engine has enough rpm to press all 4 shoes into the bell the spring preload is neutralized.

Reason for doing this is that the middle part is attached to the crankshaft, with ball bearings, and turns

30 degrees once every 4 shoes press against the bell, so also be pressed from below the shoes.

The result-better acceleration

There is no slippage occurring anymore and this will protect your clutch shoes for wear and damage!

When the throttle is released the springs are again activated within milliseconds.

With this new system the wear of the shoes is significantly reduced.
