Quick Overview

Tech Pulley 20% Torque Spring for 250cc (BLACK)


Tech Pulley 20% BLACK Clutch Srping for 250cc and 300cc clutches. 

OD = 68mm

For most torque (clutch) springs after they are in use they lose force, strength and tension.  Most springs lose around 12% recession and sometimes more after 1000 kilometers (nearly 625 miles) of use.   

With the Tech Pulley 20% torque spring, after 1000 kilometers our torque spring only has a 1.5 - 2% recession, which is extremely unique and quite amazing!  The reason the recession on the Tech Pulley spring is so low is because these springs are made of high quality material AND before they are sold they are recessed in the factory.  These factors are why users cannot feel any loss of power as the loss was already made at the factory during production.     

From the take-off position the Tech Pulley spring works like +800rpm torque spring, but during re-acceleration 
it works like a +1200rpm torque spring.
