Set of 8 Titanium Retainers for your Honda CB 750 Four SOHC up to year 1977 - two valve air cooled engines. Does not work with 78+ F2 cylinder heads.
 
Made of best grade titanium - Grade 5.
 
The original retainers weight 13,3g and the titanium retainers weight 9,3g.
 
These retainers have a smaller profile/height (less 0,5mm) to allow for more valve lift without contact with oil seal and without requiring valve guide modifications.
Using lightweight titanium retainers allows for more aggressive camshaft profiles (lift and duration) without losing control of the valve and increased rpm limits - a must for any performance / race engine.
