Stud bolt set FABBRI RACING made of high-strength steel incl. cylinder head nuts.
The set includes 4 studs in M7 with 160mm length and 4 cylinder head nuts in brass. The studs are extra long (20mm longer than stock on 125cc) to allow the use of crankshafts with 54mm stroke and more.
The studs are made of high strength steel and have a wrench flat 6mm for better de/assembly. This allows the stud to be easily screwed in/out with a standard open end wrench.
NOTE: Despite high-strength bolts, the tightening torque for the common aluminum cylinders should not be more than 14-15Nm.
