Tourex News!!

Tourex Bigspeed Automatic Torque system.

Get your 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.
This clutch is especially designed for models with high power engines such as the heavy Losi 5ive-T. You can off course use this new clutch system in all models. And yes, you can personalize the characteristics of the clutch by changing the spring strength and shoe combination!


Available in spring 2015 pre order now.
