Lambretta Crankshaft, 60 x 110mm, GP, SIP
Probably one of the best simple crankshafts on the market, these are extremely tight on the crankpins unlike most cranks out there.
These are based on a standard Gp designed crank, no balance weights to come loose.
Comes in a 60 mm stroke with a 110mm con rod.
Comes with race spec con rod, race bearing and the all important crank shims as all decent cranks should have.
These SIP crankshafts are excellent quality and are manufactured by Primatist in Italy.
Supplied with:
• 1 x standard small end bearing (16x20x20)
• 1 x wide small end bearing (16x20x22)
We've come across some SIP crankshafts that are not tapped deep enough on the drive side hole, it's advised to run the special MBU0917 8 x 1mm tap down the threads so the drive bolt doesnt get damaged.
