ONG titanium clutch retaining screw

This new ONG clutch retaining screw has been made from grade 5 Titanium due to its better thermal expansion characteristics compared to steel. This will make it possible to unscrew/screw without problems, even with a hot engine. It has a total length of 9mm, of which 6mm are thread, and a protrusion from the crankshaft of only 3mm so as to avoid collisions with the tank in case of excessive flex of the chassis. The new geometry eliminates any rubbing between bearing/bell, while the additional external diameter protects the bearing from dust and foreign debris.
