Stage6 Small End Bearing HQ silver 12-to-10mm Adapter 10x17x13mm, Minarelli.

We had this reducer bearing manufactured specifically for us; it allows for using crankshafts with conrods for 12mm piston pins on cylinders with 10mm piston pins. This way you can switch between high-end, sport and original cylinders without having to replace the crankshaft.

We recommend to replace the small end bearing whenever installing a new cylinder or crankshaft.

In addition to the common sizes, we also carry an extra-wide 10mm bearing. With some cylinder kits, the bearing has too much play and may wear unevenly. Also available - 13mm and 14mm bearings for all Stage6 R/T and Malossi BigBore kits.
