TUNING PRODUCTS FOR EVERY USE

STAGE6 R/T

CRANKSHAFT

Stage6 improved their R/T long-stroke crankshafts and redesigned the crank webs. The 16mm crankpin was replaced by a 18mm one for improved durability. The webs are reinforced, the thrust washers are silver-plated, the 90mm connecting rod is forged.

Originally developed for use with Stage6 R/T 95cc cylinders, but it can also be used with other large displacement cylinders.

HPC CRANKSHAFT

HPC (High Primary Compression) crankshaft by Stage6.

Full-circle crankshaft (no plastic inserts), suitable for up to 16,000rpm. The use of top quality materials and excellent workmanship and engineering allows for use with very powerful racing and “Hyper Racing” engines. Full-circle webs provide increased primary compression in the crankcase; rotational inertia at high rpm is increased and engine response is improved.

CRANKSHAFT BEARINGS

When it comes to high-performance engines you should not be too stingy when it comes to buying crankshaft bearings. Scooter-Attack collaborates with leading European and Japanese manufacturers of bearings and oil seals such as SKF and Corteco.

These high-quality crankshaft bearing kits come in 2 versions, with metal cage or with polymer cage. Both types can, according to SKF, be used up to 20,000rpm and have of course the necessary bearing clearance (C4). Sufficient lubrication and proper installation of crankshaft and bearings are of course essential for long life.
