High-performance crankcase from the TPR Factory range, designed for Minarelli AM6. Developed specifically for racing use, this engine casing is suitable for big-bore 100cc cylinders.

The casing accepts 100cc cylinder kits with long standard type cylinder studs, without the need to machine the cases. It is fully compatible with the original AM6 gearbox, clutch, & ignition, making installation straightforward.

The cylinder base has the space and stud pattern to accept a flange mounted 100cc cylinder kit although You will need to modify the water pump outlet for these crankcases to accept a flange mounted cylinder, however, the possibility is there.

The intake has been re-engineered for larger flat-slide carburettors and is designed to work with a V-Force 3 reed block to improve airflow.
